Easter sunday in C++ - c++

Is there any library that will help me to get date for easter sunday for given year in C++? I'm looking for something like easter_date or easter_days in PHP. It can be Linux only.

Here is codeproject example

Most PHP functions are actually implemented in C.
If you have an SVN client you can get the source code for the PHP easter_date and easter_days functions here:
https://svn.php.net/repository/php/php-src/trunk/ext/calendar/easter.c
I have no idea what the ethics of using this to create your own function is.

http://www.dateofeaster.com/ has an algorithm. It seems to match the PHP implementation.

C++ export into HTML with dates

I have probably simple problem for u. Hello.
I´ve written a function to count exact date of Easter in the year which someone will put in. So for example somebody puts in 2016 and he will get out sentence like "Easter will be 26.03.2016" .. If he will put in more years, like "2016, 2017, 2020 - 2024", he will get exact days of Easter in these years. But what I need to do is get these dates from C++ to HTML file dates.html .. Can somebody give me advice how to do it? Thanks very much.
Open the file (using for example ofstream), and write the html to that.
Show us some code and what you have already tried. Also take a look at this. It is a simply guide about if/ofstream and file-handling in C++.

Mapreduce in MPI

I want to use word count on this dataset :
http://snap.stanford.edu/data/web-Movies.html
I can't find a program on the internet which will help me to do so.
Please suggest something ?
This is something that is pretty amenable to MapReduce. If you're a python guy, you might like mrjob, which actually uses a word count example in a lot of their documentation:
http://pythonhosted.org/mrjob/guides/writing-mrjobs.html
Have a look at easyLambda. It is a C++ and MPI library based on data-flow and map-reduce. It has a word-count example as well.

Is there a search engine for C++ commands?

I do C++ and R programming since last 3 years.
I wish to know is there a search engine for C++ commands where I can find all the details regarding the command.
This is the example of what I am looking for:
This is a search engine for R commands:
http://www.rseek.org/
Google works pretty well.
If you only want C++ hits, use the site: restriction, as in "site:cppreference.com emplace_back"
Perhaps "site:cppreference.com pow" is a better example, since pow by itself would normally come up with many unrelated hits.
Of course, keyword search works also, try "site:cppreference.com natural logarithm"
I use this often: http://www.cplusplus.com/. It has a search box.

Netbeans: C/C++ file-template variables documentation needed

I'm looking for a faq or overview on C/C++ template-file variables in Netbeans (7.0).
(Not to be confused with the template technique). Those you see under Tools > Templates > C++ templates.
e.g.
%<%CLASSNAME%>% %<%DEFAULT_HEADER_EXT%>% %<%DATE%>%
which are automatically filled when you create a new cpp/header file out of that file-template.
The help for the Java template-variables with Freemarker is very extensive, but I found nothing for the C++ equivalent.
When I did a search on CLASSNAME DEFAULT_HEADER_EXT, google gave me 5 results... which were not helpful. So if there is a reference or api, it seems to be hidden somewhere... Not even the netbeans site had any information about that.
And if there is nothing, maybe someone can at least tell me if there is a way to format the %DATE% variable (like this in Java's Freemarker format: ${date?date?string("yyyy")} ).
Still no luck... can't believe that such a feature is not documented... Any help would be appreciated :)
Thanks
I know it's an old question but just stumbled on it and think it's good to have it mentioned:
The documentation of all predefined template variables including the date formatting may be found here: http://wiki.netbeans.org/FaqTemplateVariables

Parsing iCal/vCal/Google calendar files in C++

Can anyone recommend a ready-to-use class/library compatible with C/C++/MFC/ATL that would parse iCal/vCal/Google calendar files (with recurrences)? It can be free or commercial.
there is a parser in PHP for iCal, you can downloaded and check the code to suit your language.
for vCal/vCard parsing there's a C Library.
for Google Calendar I couldn't find any exact answer, so, try to Google it.
For vCal you can try the CCard project on SourceForge:
http://sourceforge.net/projects/ccard
It's a C library but it states Windows as a supported platform.
*Edit: balexandre already linked to it :)
The only problem with the CCard project is that it's a generic parser (similar to what I already have implemented myself) - what would be really valuable to me is something that "understands" all varieties of recurrences and such. Those differ between vCal and iCal as well, adding to the complexity.
