Running Normal Functions inside of a class

I've been working on a big project and I'm trying to call a function from inside a method definition in a class. The function is outside of the class file entirely but in another source file. The compiler says I'm making a call to an undeclared identifier. So how do you call functions from inside class methods? Thanks.

you'll have to include the file that has the prototype, which should be in a header file. If you have this function in your main cpp file, just make an h file for it, and put the prototype in there
