Compilation of a header file in c++

[krishna mohan]

Hi..am just learning c++...i have a doubt..

Suppose you have a header file and you include it in your main program by using the #include directive..then do you have to compile the header file separately? Or does it get compiled with the main program?

Or does it get compiled with the main program?

Yes, all the #include does is copy the text of the header file into the .cpp file before passing it to the compiler

I guess your yes means that one does not have to compile a header file separately...and it gets compiled with the main program..?
