You can write the program on dev c++ or turbo c which can be easily download from google search .but from my opinion dev C++ is the best one .

after the dev c++ install go to the file and then new and after that source file after this a new page is open the you can write program on that page.

I taught u how to write the program .

first very easy step

Write a program to display hello on output screen.

#include<stdio.h>       //#include is an preprocessor 

                                   //stdio.h is an library

int main()                     //int main very all the work will done on the scope

                                    //scope open

                                     //printf is defined on stdio.h library

{

 printf("Hello");        // ;(semicolon) is very important after the end of the line

return 0;                     // it will return  value

}                                   //scope closed

after writing this program u type  f11 for compiling.
