I'm trying to create some classes that work together via Operator Overloading. I have the main.cpp and the Distance.h files exactly how I want them, and now I just need help properly setting up my Distance.cpp file to link properly and run accurately with them. Here's a look at what I've got so far. Any help and tips would be GREATLY appreciated. Again, the main.cpp and the Distance.h (header file) do not (CANNOT) be changed, so the focus is on the Distance.cpp file. Thanks in advance for any help!!

public:

Distance(int initialValueInInches);
// used for int x = dist1;

}As you can see, I haven't filled in all the operator void functions yet, but thats also part of my struggle. Let me know what you guys think!!
