Before I knew that C was faster than C++ I was able to write some simple code where C executed faster than C++'s speed.
So my question is: please explain then reason behind this.
If this has already been explained elsewhere on this site or the internet, please share a link.
The reason behind this is your poor test.
C is not faster than C++ because C++
is a superset of C.
Here it is!

I am trying to figure out the complete code as explained at:
http://www.drdobbs.com/windows/microsofts-c-amp-unveiled/231600761?pgno=2
I am trying to find out how to generate the complete code examples with of Simple C++ AMP Version? How do I define the grid object? Which header do I need to use direct3d? It seems my Visual Studio 2012 flags these as undefined.
Thanks
I've never seen restrict(direct3d) before. I suspect it's supposed to be restrict(amp).
You'll also need to #include <amp.h>

I'm sorry, I'm lost.
I program microchips, and I primarily work in assembly, but I have much more experience in C and C++. I know that there is a way to embed C++ into the microchip, I just need to know how. If I need to make a clone of C++, I am willing, if someone will tell me how.
Thanks in advance.
1) Write program in C or C++.
2) Compile program.
3) (Optional) Test program on an emulator.
4) Burn program into desired microchip.
If you give us specific chips, we can give you more details of how each of the steps works.

I am looking at ways of creating my own DBMS from scratch in C++ (just for fun and educational purposes). I am stuck with the place to start it. Can anybody tell me how I should begin (design) this. Will postgresql code and the architecture be of any help?
Thanks in advance.
Have a look at SQLite and its doccumentation. it might be a good point to start.
Start by reading "Transaction Processing: Concepts & Techniques" by Gray and Reuter. It goes through all the major components of a DBMS. Following the references is very interesting.
It is almost 20 years old now, but still very relevant.

I am currently learning C++ and now understand things like classes and pointers, etc.
Anyone have an idea of what programs I should practice writing when teaching myself C++?
Try reading books that have exercises at the end of every chapter and try making them.
You can check Thinking in C++. The books are available online and they have exercises at the end of each chapter.

As you know, C++ allows multiple inheritance. But, would it be a good programming approach to use multiple inheritance or it should be avoided?
Thanks.
In general, it's not needed and can make your code more complex.
But there are cases where it's useful. As long as it's useful and isn't causing your code to become unmanageable, I see no reason to avoid it.
