Question

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?

Answer 1

The counter variable for the sheep count should be declared and initialized before the constructor in the class. The extern keyword should be used to declare the class in the receiving C source file. A constructor is defined when there is a need to instantiate an object with an argument and an assignment operator is used to initialize a variable. The const keyword is used to specify a variable whose value should not change during the course of the program execution.

Step-by-step explanation:

The C programming language is an object-oriented programming language and has variable specifiers to define variable scopes in a program.
