class CRectangle {
    int x, y;
  public:
    void set_values (int a,int b);
};

This is an example of a class definition, that you can define in a header file. Do notice that we currently have no implentation of set_values. So therefore we make a .cpp file and put this in there:

#include "HeaderfileName.h"

void CRectangle::set_values (int a, int b) {
  x = a;
  y = b;
}

The reason for doing this is that your code gets a lot more organized, especially when you have hundreds or thousands of lines of code.
