Hi, I am kind of new to C programming and I got two different files. One is my main .c file which I am using to make my main program and I got another file with an extension of .h. The .h file has some some functions built in as well as declared variables. I am trying to make use of these functions in my main .c file.

I included this line on top of my main .c file

#include "file.h"

This line should include the .h file on my main program and also give it all the functionality and variables, but I am still unclear on how to make use of them. Can anybody point me in the right direction?

Thanks
