Question

I know how to define a class method inside of the same file with which the class is in.

For example:

class Robot
{public:
 int location;

 void Moves(); //Class method to be defined
}

void Robot::Moves()
{//Method definition here }

I do NOT know hot to define a class outside of the file in which the class is in. I tried creating a .hpp file and defining a class method inside of it, but my compiler signified that it could not load a class definition from a file other than the one the class was created in, or it would be as though I was placing a function’s definition before the include directives.

Please note: The original class file is also in a .hpp file, as I have yet to learn how to use .cpp files other than the main one.

This is done using C++/Win32.

Answer 1

Create a .cpp file along these guidelines

• Include your class header file in your .cpp file
• Include all necessary headers you would use in main.cpp
• use the scope operator for your class

#include <iostream>
#include "foo.hpp"

foo::foo()
{
//    code here
}

void foo::OtherFunc()
{
//    other stuff here
}
