how we make a c++ header file?

You should consider buying a good C++ book before asking basic and inane questions here. We love to help, but a question like that leaves us worried what we can say, and hope you will understand it.

If you are using Visual Studio

Right Click Project -> Add New Item -> Header File -> Add header file Name -> OK

and here is your new header file using MSVC


If in case you are using turbo C or GCC, use notepad

open notepad and save the file within inverted double quotes as "filename.h"

you can save it to any path as required.

Then in you cpp file, you can include this file as using include statement


Here is an example...




#include "headerfileName.h" //including the header file you created

int main() {

//code

return 0;
}

Best of Luck..! :)
