I've studied C++ as a college course. And I have been working on it for last three years. So I kinda have a fairly good idea what is it about. But I believe to know a language is quite different from using it to full potential. My current job doesn't allow me to explore much.
I have seen you guys suggest studying a open source project and perhaps contributing to one too. So my question is, can you suggest one(of both?) to start with that is simple and doesn't overwhelm a starter.
I was in the same situation 12 years ago when I got my first programming job out of college. I didn't do any open source but I managed to gain a lot of practical and advanced C++ knowledge by reading books (the dead tree kind).
In particular, there was an excellent series by Scott Meyers which I feel helped the most in turning me from newbie to professional:
Effective C++: 55 Specific Ways to Improve Your Programs and Designs
More Effective C++: 35 New Ways to Improve Your Programs and Designs
Effective STL: 50 Specific Ways to Improve Your Use of the Standard Template Library
The topics in these books range from beginner to advanced. It took me about 2 years working in C++ to understand every chapter in these books, so don't be disheartened if it goes over your head at some point... just try reading it again later :)
If you're willing to climb the very steep learning curve, I would think that you could do worse than studying parts of the boost libraries. I don't think there is another similar body of C++ code out there that is pushing the boundaries of what can be done in C++.
re project selection: you'll want to hack on something that has some relevance to you, otherwise it's just unpaid work. i might suggest eg. Pure, but will you find enough interest?
re advanced code: see Boost
Obviously learning something like this does not happen overnight; You can study existing open-source projects like other posters suggested. However, I have one more suggestion: I suggest joining one of the big IRC c++ channels (for example #c++ on efnet or freenode). Of course most of the questions / discussions going there are basic; however quite often interesting discussions and questions come up. Over the several years I've learned quite a bit just by participating in channel discussions.
My main advice would be that you do not need to stick to C++ to learn technique.. Study Erlang, Lua, and Haskell (lots of others). You will learn so much from these language that you can apply in C++.
Google protocol buffers is a very well written C++ application that sticks to the features of C++ that are proven in the industry -- i.e., they don't go over the top with features that cause headaches for using the code.
In terms of learning to use C++ to its full potential, well the full potential is often hidden. There are very few exceptional C++ programmers, even in the open-source community. So I suggest you read some books. Like the books from Scot Myers and Herb Sutter (all 6 of em).
Boost is an amazing library and has a lot of good code, ranging from simple techniques to very advanced techniques. It definitely touches all of the bleeding edge of C++ idioms. The problem with boost is, it doesn't work well with modern IDE features (code-completion being the main problem), and it has a LOT of symbols :D. It is the place to learn about generic programming and template meta-programming, the former represents the most advanced and immediately-usable idioms, and the latter you can skip for the immediate future.
Apart from the Scott Meyers books DSO has already suggested: Participate on SO and try to answer other people's C++ questions. If you don't know the answer, wait a little until some good answers are posted. You will probably get some idea where the gaps in your knowledge are and you could do some more reading to fill those afterwards.

I am an undergraduate student and I recently was hired for a co-op for this summer and next fall. From what I understand I will be writing a lot of C++ which I am comfortable with but I don't have a huge amount of experience actually writing C++ in particular.
I wanted to take the time to really dive into C++ and become much more proficient with it. Does anyone have any particular resources that I could use to get some more experience before I start my job?
TopCoder was featured on This Developers Life recently and the algorithm challenges are a great way to hone your skills in various languages including C++
Getting involved in Open Source projects is a regular suggestion.
Good books from many authors are listed conveniently in many places including Amazon.com
To really deeply understand the language and learn some best practices I would recommend to read Herb Sutter's books, in following order:
C++ Coding Standards
Exceptional C++
More Exceptional C++
Exceptional C++ Style
The first one is very useful if you don't have experience with industrial development in C++.
Read The C++ Programming Language by Stroustrup cover to cover, and then read it again and again. Then, as you work with C++ programs, keep referring back to that book to remind yourself of the details of various topics.
It is, by far, the best book on C++ available, and since the author invented C++, you will get a good sense of the intentions and rationales of the various language features.
Once you have mastered the contents of that book, the next step is to familiarise yourself with the C++ 03 and the upcoming 0x standards. Reading a language standard can be hard, but once you get used to the style, standards are invaluable resources.
It is very important to be familiar with the authoritative resources and not get lead astray with possibly incorrect or out-dated information out on the web. I've seen programmers make really dumb mistakes because they just searched on Google to find out how some language feature works.
You need to practice and read manuals (tutorials) for c++.
Else you can try to look at internet website who are not protected and look at the source code.
Everybody work hard for what they learn and apply.
Good luck!

I'm something of a new, reluctant convert to C++ from a Pascal, Ruby, and PHP background. I haven't worked with Pascal since a few months of torture with "Delphi Turbo;" since then I've practically been eating and sleeping Ruby and PHP. I'm already well acquainted with object oriented programming and many various subjects.
My main trouble is that I already know the rudiments of C/C++ programming, less the actual experience of working with C++. I worked with C for long enough to realize that even without macros, etc, I didn't want to work with it. (Some of the disgust was from maintaining a CGI application in C, when accustomed to Pascal's automatic string management.) I know just enough C++ to be dangerous to myself and anyone else unwitting enough to use my "code."
I'd really like to work up to a good enough understanding of C++ to use libraries like Crypto++ and Boost without major problems or in-depth knowledge of the language's intricacies. I just need to figure out how to work with C++ without killing myself (either with C++, or with the long-standing dislike that I'm already battling).
What are effective resources that will teach me C++ without assuming that I must be retaught all basic programming? I'd rather not relearn concepts that I already know, unless the paradigm in C++ is significantly different. I'm also learning on my own time, so don't recommend me a book complex enough to need a guru to explain to me, please! And I have an effective budget of $0 for learning C++, so please keep suggestions to quality online resources or books common enough that I could likely find them at the library.
Read Effective C++ by Scott Meyers - it's a good guide for getting past the basics of C++ and showing how to write and use "correct" C++ code
The C++ FAQ Lite is a great resource.
I highly recommend Stroustrup: The C++ Programming Language (Third Edition). As the author of C++ he is the authority on the language, and the book is useful as a reference as much as it is for learning the language. It's common enough that most good general purpose libraries will have a copy. He goes into quite some depth on all the features of C++, including explanations of why certain design decisions were made in the language. Personally, I think this is the best book around for programmers to learn C++.
Once you have a good grip on core C++, David Abrahams and Aleksey Gurtovoy's book, C++ Template Metaprogramming, goes into further depth and provides many examples of how C++'s template system allows you to perform complex compile-time programming, a highly valuable skill these days. This one is a little less common but you can probably find it at a university library.
I can give you a couple of keywords you might want to research in more detail:
RAII (Is pretty much the technique that ensures you don't have to worry about memory leaks. Very convenient)
Generic Programming (The STL in particular. Experiment with iterators and the standard library algorithms, and see just how powerful these abstractions are. They're a key part of what I like about C++)
Functors (Perhaps too simple on their own, but the way they can be used instead of function pointers with the algorithms mentioned above is interesting)
And just get familiar with templates, and "mild" forms of template metaprogramming. (Traits classes, for example, and (partial) specializations.
And just keep an eye on the C++ questions here on SO. A lot of interesting topics are regularly brought up.
But the best advice is probably to keep it completely separate from C. Forget everything you learned about how to use C. It either doesn't apply in C++, or leads to inferior code that is harder to read and maintain.
It's an interesting language in its own right, and has a number of unique features. Leverage those, and it can actually be fun to work with C++. Treat it as an overengineered Java, PHP or C, and it'll just make you want to throw up.
You need to write code. A lot of code in C++. There is no substitute. You also need to read good code.
I agree with the suggestion for Scott Meyers' books though. Those are pretty good.
Part of your learning will be the leap from procedural programming to OO.
I would highly recommend the book "C++ Common Knowledge" by Stephen C. Dewhurst. Don't know if it's common enough to be found at the library (it's not at mine, but my library sucks for computer books that aren't 5-10 years out of date), but it does an excellent job of taking the complex aspects of C++ and making them easy to understand, without dumbing anything down for beginners. Definitely worth the investment.
To quote from the back of the book:
This book is for you if
You're no "dummy," and you need to get quickly up to speed in intermediate to advanced C++
You've had some experience in C++ programming, but reading intermediate and advanced C++ books is slow-going
You've had an introductory C++ course, but you've found that you still can't follow your colleagues when they're describing their C++ designs and code
You're an experienced C or Java programmer, but you don't yet have the experience to develop nuanced C++ code and designs
You're a C++ expert, and you're looking for an alternative to answering the same questions from your less-experienced colleagues over and over again
C++ Common Knowledge covers essential
but commonly misunderstood topics in
C++ programming and design while
filtering out needless complexity in
the discussion of each topic. What
remains is a clear distillation of the
essentials required for production C++
programming, presented in the author's
trademark incisive, engaging style.
Here is a link to a question with answers that should help you.
https://stackoverflow.com/questions/1227764/i-need-to-improve-my-c-skills-fast-is-this-realistically-possible/1227805#1227805
For effective stuff you can find online Cplusplus.com has a pretty good reference and information.
If you can find the book "C++ Common Knowledge" (Stephen Dewhurst) at the library or cheaply online, I would add that to the list posted on the StackOverflow link above as well as "The C++ Programming Language" (Stroustrup). Going through the questions under the C++ tag right here on SO should give you some good pointers and code examples to get you on your way.
Here's a list of good C++ books which teach you C++ rather than basics of programming.
Sit down and write some C++ code.
I am very interested in c++ and want to master this language. I have read a lot of books about c++. I want to read some library source code to improve my skill, but when I read the boost library source code, I find it is very difficulty.
Can anyone give me some advice about how to read boost source code and before I can understand it what kind of books about c++ should I read?
If you're starting out in C++, the boost source code is probably not the best place. It's where the wizards hang out and they deal in template magic. I think a better starting point are Scott Myers and Herb Sutters books (in that order).
Some versions of Scott's book can be a bit out dated but they are still strong in the fundamentals. Herb's books are worth reading many many times and are an invaluable tool. Once you've gotten through both of those authors, then would be a good time to tackle the boost source code.
Scott Myers: Effective C++
Scott Myers: Effective STL
Herb Sutter - Really I would go for anything with Effective and C++ in the title from this list.
I can't give advice on how to read boost code, but I can offer some other advice.
Stop reading and start writing :) Reading is valuable, but you won't learn anywhere near as much unless you start writing code yourself. Start with the basics. Read the beginners books and type out the samples (don't copy and paste). You'll learn by having to fix the errors that are the result of you mistyping. Play with some of your own ideas for simple applications and go from there.
Starting off by reading boost source code is a sure fire way of scaring yourself off the language and/or ending up very confused with a lot of questions.
Start small, work your way up.
Since you mention that you want to learn the dark art of meta programming then I would recommend "Modern C++ Design" by Andrei Alexandrescu.
Meta programming is a very complicated area and is not required most of the time. Once you learn about it, it is very easy to think that it can solve all your problems. It becomes your new favourite hammer.
I would also recommend becoming a very proficient user of libraries based on meta programming like boost and loki before you add it to your own code.
Two different programmers used meta programming in parts of the code base I am responsible for. While they were skilled programmers a commercial product should not be treated like a playground. These are probably the worst area's of our code base now, very complicated and very brittle esp when you add support for new compilers. If I was responsible for the code when they were written they would not be here, now they are too expensive to replace.
In short you very rarely need meta programming unless you are a library writer. And you cannot be a library writer without being a very accomplished library user.
I imagine boost uses a lot of advanced c++ features like templating etc. Boost libraries tend to be very complicated as they try to follow strict programming standards and styles for them to be compatible with things like the STL.
Quite simply, if you don't understand it, you are probably in over your head. and if you do understand it, you don't really need to be reading it anyway. Don't jump into the water if you don't know how to swim... You've essentially tried to swim up a waterfall.
Yeah, there is some truly awful stuff in some of the boost libraries. If you want to read some very nice source code, try checking out WebKit or some of the Google open source projects (like Chrome or Protobufs).
Id suggest you start off with something like Lipmann's Premiere(other begginers books of
your liking). Then, when you're comfortable with the code, you can move on to Herb Sutter,
Alexandresku to broaden your horizons, acquire a more complete view on the soft dev. And
MOST IMPORTANTLY - to be able to cede well one has to code A LOT, as it is a skill just as
any other and it takes practice to master.
P.S.> If you're confident you can pick up Stroustrup right from the start along with other
book(s). I don't think that theres another source on C++ just as complete as the authors.
For learning anything, i mean, there's a principle which is very important. To fill the belly we have to learn how to cook, to chase a girl we have to learn how to flirt with, to resist the beast we have to learn how to make fire. So finally we find that we learn and master a thing in the process of solving a specific problem.
In my perspective, it's best to learn and master the c++ language with diving into a specific problem waiting for solving. You analyse it, stick with it, try it, many times, with facing various difficulties, and solve it, finally, and bravo. With the delight of success you will find that the C++ language has been conquered, by you.
I've been doing C++ for 3-4 months in a local college and I'm doing extra reading / learning using Accelerated C++ and so far, I've "finished" it. Now, I'm wondering which book to get next that'll help me code better in C++.
I've looked around and found this: The Definitive C++ Book Guide and List
I'm sorry if this question may seem stupid for most of you here but I'm a bit tight in cash and I would really want to invest in something that's "right" for me at this time.
Right now, I only know the basics of stuff like (classes, templates, STL, iterators, dynamic memory management).
Do you have any suggestions? Should I focus on STL or templates..? Or should I read something like The C++ Programming language?
If you haven't yet read Stroustrup's books, they are definitely a good read. There's nothing quite like reading about the language from the person who designed it.
Whenever I learn a new language, I always try to find the canonical reference material written by the language designer or somebody very close to them.
In addition to reading Stroustrup's books (suggested by another answer here), I'd suggest his two FAQs as a great starting point:
Bjarne Stroustrup's FAQ
C++ Style and Technique FAQ
They both link to further reading material.
These two, along with the C++ FAQ Lite, are required reading for new programmers at my workplace.
Once you're even a bit more comfortable, consider jumping in to the community: subscribe to something like the boost mailinglists, watch the blogs of big name figures like Herb Sutter, read Alexandrescu's Guru of the Week articles. You may feel like you're in over your head (I still do often after many years of reading the lists) but you'll learn a ton, especially watching the language grow and evolve. (And this stuff is free!)
You can get more understanding from watching how a language changes over time, and how people actually use it, than you can from a million hours of memorizing the standard. (Not that shelling out a few bucks to have a copy of the ISO/IEC standard around is a bad idea, mind -- great for reference from time to time.)
As for books:
after the Stroustrup books,
start with the Meyers ("Effective") books.
I'd also recommend C++ Coding Standards -- a great amount of work went into gathering the "common sense" of the users of the language in this book.
Then if you want to blow your mind you can look at Modern C++ Design or some of the fun template metaprogramming resources...
Above all, just stay connected and interested. Mailinglists, blogs, websites, academic papers, magazines, whatever -- choose what suits you best, don't expect to follow everything all the time, but keep your ears and eyes open; find aspects that interest you and follow them!
The C++ Programming Language would give you the best overview of the language. It sounds like you have that but the section on object oriented programming is worthwhile. I'd probably spend more time learning about object oriented programming at this point than more specific C++ features.
A book like "Code Complete" might be a good choice for you.
I feel like you can probably make more progress learning to program by tackling real programming problems, rather than reading another book.
I certainly don't discount the value of books as a programming resource but I do think there is no better way to learn a programming language than writing real code. Given your financial constraints, you have the additional motivation that writing code is free.
Concentrating on a particular part of the language or a pattern for programming might be interesting, but a specific problem to solve will give you context that, in my opinion, is a more powerful learning mechanism.
Of course, you can't write code in a vacuum. You have already read Accelerated C++ which will probably give you more than enough to get started writing code, but there are also a whole pile of resources on the net that will help (StackOverflow is a great place to start).
Tutorials for Win32

These are my favorite:
Effective C++ - Scott Meyers
C++ Standard Library Tutorial and Reference - Nicolai Josuttis
I might suggest a library card, or hanging out and reading Border's, to make sure the books are helpful for you.
a Good book for templates - C++ Templates by David Vandevoorde, Nicolai M. Josuttis
Learn STL more and more, there is a
lot more to learn.
learn Boost. This would change how
you think about programming in C++.
If you want to go very deep, read Stroustrup's papers. Select a paper now and then, print it, read it carefully. Stroustrup is an excellent writer. reading his papers would make you a superior C++ programmer for sure.
My favorite list is :

If you don't want to spend money, you should learn multi-threaded programming. The basics are already in the books you have, and described in API documentation. Try to actively create a program with many threads that communicate back and forth, and then multiply the number of threads to see if you've made a good design.
You'll want to read up on Semaphores, Mutexes, and Critical Sections.
I take three approaches to multi-threaded programming:
Use a PostMessage style communication between threads
Pass thread-safe objects between threads through which data is stored and relayed
Initialize a thread on start-up, let it run on its own, and then retrieve the data at the end of the run
If you're ready to spend money, I would recommend Design Patterns as a good next-read. It's more generic, and you'll find some of the ideas make sense.
I think you started out with just the right book! For those who didn't know, this book starts with STL at the beginning and leaves pointers for the end. Most programmers learn C first, and consequently have a forever distorted view of what C++ can be.
It might be really interesting for you to now read 'The C Programming Lanugage' by Kernigan & Richie at this point. This is probably a necessity if you want to understand the mindset behind most C/C++ code in the world today.
But more important than your next programming book is to find a medium-sized program you really want to write, and go after it. Use all kinds of reference materials for the project. Incorporate a boost library or two in your program.
If you are tight on cash, read How to Think Like a Computer Scientist. Also read the FAQ lite.
I have been learning C++ for three months now and in that time created a number of applications for my company. I consider myself fairly comfortable with C++ / MFC and STL, however I don't just want to be an OK programmer, I want to be a good programmer. I have a few books on best practices but I was wondering if anyone could suggest reading materials that helped them and any disciplines which should be encouraged?
Thanks!
I would start with the Pragmatic Programmer, Code Complete, Refactoring and Design Patterns.
For C++, Scott Meyers books are very good, and will help take you to the next level.
If you don't already have it C++ by Bjarne Stroustrup, 3rd Edition
Uhm... Teach Yourself Programming in Ten Years (Peter Norvig)
3 months into c++ and you're already comfortable with it? Sheesh, I've been learning c# for over a year and have taken numerous Microsoft courses and I'm nowhere near comfortable with it.
That being said, you'll hear Code Complete tossed about as a very good book. I'm in the process of reading it now.
Marshall Cline's C++ FAQ Lite.
Herb Sutter's Exceptional C++.
Large Scale C++ Software Design by John Lakos gives guidance on design methods that will make your C++ more maintainable. It is pretty hefty but you can dip in and still get some benefits.
Somewhat off-topic: rather than suggesting books to learn, I'd like to mention some broad topics to consider.
Threading. This one is not much in demand if you use MFC, but in many other areas it's indispensable. The mechanics of threading APIs are easy to pick up, but learning all the corner cases takes a lot of time and practice.
Closures, Map-Reduce and other lisp-like techniques. Find out what they are, why they are not supported in C++, and how they are imitated in C++ (functors, and many other cases of stateful callback objects). For this I actually have a book: "Structure and Interpretation of Computer Programs".
Command Line. This gives you an idea on when not to code your own programs. Command line would be Unix command line - I don't know about MS's latest experimentation in this are, but cmd.exe is awful. Get Cygwin and start experimenting.
Scripting languages. This gives you an idea on when not program in C++. My favorite is Perl, but many people say Python, Ruby and whatnot. Hey, learn XSLT if you're so inclined!
I am sure I left out other areas. I'll mark this as Community Wiki - feel free to add.
Good blogs:
Guru of the Week, and all the books by Herb Sutter. Those will give you quite a lot to chew already.
Modern C++ Design by Alexandrescu if you want to get a good feel for what you don't yet know, and probably don't want to know.
Code Kata's for practice!
I have read several (not complete but some parts) of oreilly books on VB.net they are quite good, but if you want to be pro and have the time...
You can try out MSDN forums, help other people and discuss with them hard and complex problems, I think it's the best way..
learn another language. even if you won't use it, it's great for mind-opening.
I'd advice Lua, Scheme and Python. but almost anything else would do. (the most different from C, the best)
Josuttis and Vandevoorde - Templates: The Complete Guide
As I see, nobody mentioned Bruce Eckel brilliant books "Thinking in C++". IMHO, it`s one of the best books to start your C++ development from. From my point of view, first volume is more helpful that the second, but both of them worth reading.
http://www.amazon.com/Thinking-C-Introduction-Standard-One/dp/0139798099/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1227890306&sr=8-1
I lot of folks can suggest more modern, up-to-date books. But I still recommend The Annotated C++ Reference Manual by Margaret A. Ellis & Bjarne Stroustrup.
The ARM was published back in '90. It's become somewhat outdated with respect to templates. STL is (obviously) absent. (Though the website at sgi.com does a good job of covering STL!)
However, the ARM is dirt cheap (used). (Shipping will exceed the cost of the book.) Its signal-to-noise ratio remains off the scale. It's very good at digging into C++'s dirty areas, explaining what was done & why.
I still use it as a reference. I rank it up there with K&R.
Dietel/Dietel "How to program C++"... I still have this book on my desk (10 years in).. Every once and a while I re-read a chapter. I'd definatly get the Code Complete, as other have suggested. Infact read that first.
To get a better understanding of object orientation, spend some time in a Smalltalk. Squeak is a free download. Then read Richard P. Gabriel's Patterns of Software and thereafter his Objects have Failed.
Thinking in C++ - Bruce Eckel
Symfonia C++ Standard - Jerzy Grębosz
If you do nothing else, program.
When you are not doing that read about programming and when something strikes you as interesting, go implement something with that knowledge. I've found that this is the only way to really set the principals.
Staying up to date on blogs can be fun, but it is scattered knowledge. It seems to distract more than help. But combined with google and a desire to research something specific can really cough up tons of information. But dont' just subscribe to alot of rss feeds and expect to get better.
I think really studying specific topics helps expand your ability. Research topics that intrigue you, meet people doing things like you (conferences, user groups, irc, facebook, stackoverflow, etc) and above all practice your art.
You can check out the Boost library and a number of the books written about it. While this may not have been what you had in mind, IMO, the Boost libraries are examples of well-designed modern C++ libraries that use the features of the language in pretty much the way they should be used to create among the most effective solutions for their problem domain. Granted of course, there are bizarre libraries like preprocessor and MPL which make you wonder if you'll ever have any use for them, but they're all round quite good. From my own experience, exploring the library and its literature has given me insight into how C++ can be used effectively.
