#include Header files location

Where are iostream library files as i see in my program written as #include <iostream>?

You need to check the folder in your local disk where Dev C++ is installed, For example in my case it is located on the following mentioned path.


C:\Program Files (x86)\Dev-Cpp\MinGW64\lib\gcc\x86_64-w64-mingw32\4.9.2\include\c++\iostream

As a programmer its time wasting if we write this code again and again in each program and that’s why compilers save this code in file name as iostream. and this file works like a library of code.

A programmer simply use this library by writing a simple line of #include <iostream>
