1) You have a class called Sheep that wants to keep track of how many Sheep have ever been created. Where is a good place to put that variable? 2) When an h file mentions another class, what is that called? (When a cpp file needs to use a class, they include it. This is an h file just mentioning a class, like it has a pointer of that type. You are promising the compiler that the class is in another file.) 3) What is a good guideline for deciding you must write a copy constructor, an assignment operator, and a destructor? 4) void Rock::Func( const Rock & X){} What is that argument type called and what does it do? 5) We saw overloading the = sign. How do you declare a class wanting to override the parenthesis operator?
