I'm trying to write a simple addition program in c++ using ubuntu that takes two numbers from a class in the header file and simply adds them up and displays them in the main file. Here is what I have so far:

header file: header.h

#ifdef MYHEADER_H_

#define MYHEADER_H_

using namespace std;

class myClass {

private:

int x, y;

public:

addNums();

int addNums(x , y);

};

#endif

I am not sure what to write in the source or main files to get this to work. Thanks for the help!
