Implementing Regular Expression in C++

I want to make a c++ program to match particular regular expressions, I used DevCpp and the library

#include<regex.h>

. It's not working, I don't know why.

It's showing: [Error] regex.h: No such file or directory

The headers from the C++ standard library don't have .h on the end. In this case the correct include is:

#include <regex>

You also need to ensure that your compiler supports c++11. In the case of GCC you need to be careful that you are using a recent version (4.9 or newer), libstdc++ provided a regex header long before they had provided a working implementation.
