Explanation / Answer

1. Each and every class in a C++ program (by convention) are defined in how many files?
Answer: 2(.h and .cpp files)

2. Which of the following goes into a header file when you write a class?
Answer: a. the class specification(consists of the class variables, methods, friends function names etc).

3. :: is a scope operator that you use to designate which class a function/method belong to.
Answer: True

4. Hoa many bytes of memory is set aside/reserved by the following class declaration? (enter a number, 0-1000)
Answer: 0
Reason: The definition of a class does not set aside any memory. Memory is set aside for variables of a class(objects) when they are declared.(If you are askking that, the answer would be 12(there are 3 int type variables in the class))

5. You have to #include a particular class's header file in which of the following files?
Answers:
b. all other header files that use the class
c. the class's cpp file
