How to create function in separate files

Question

Ok now we have learned we can create class in separate file but what about creating function in separate file.
Like I mean mentioned the header file then use all the user defined function in any cpp file

Answer 1

Don't forget to include your custom header files in your main cpp file and link all cpp files in order to compile the whole thing

Answer 2

You need the main function for a program.

Answer 3

The same way, you do it with classes:
.h

void func(int);

.cpp
#include "a.h"
void func(int a)
{
std::cout << a;
}
