Chapter 15, Problem 37RQE

Write the declaration for class B. The class’s members should be as follows:

• m: an integer. This variable should not be accessible to code outside the class or to member functions in any class derived from class B.

• n: an integer. This variable should not be accessible to code outside the class, but should be accessible to member functions in any class derived from class B.

• setM, getM, setN, and getN: These are the set and get functions for the member variables m and n. These functions should be accessible to code outside the class.

• cal c: a public virtual member function that returns the value of m times n.

Next, write the declaration for class D, which is derived from class B. The class’s members should be as follows:

• q: a float. This variable should not be accessible to code outside the class but should be accessible to member functions in any class derived from class D.

• r: a float. This variable should not be accessible to code outside the class, but should be accessible to member functions in any class derived from class D.

• setQ, getQ, setR, and getR: These are the set and get functions for the member variables q and r. These functions should be accessible to code outside the class.

• calc: a public member function that overrides the base class calc function. This function should return the value of q times r.

Provide a constructor that enables an object of this class to be initialized when it is instantiated. The constructor should contain default values in case no initializes are provided. Provide Public member functions for each of the following operations: set the time, print the time, increment the time by one second, compare two times for equality, increment the time by one hour, determine if one time is “less than” (comes before) another time, and final print the time in format 12 hours. Include any additional operations that you think would be useful for your class.
