This function should return the value in the member variable area. Parameterized constructor—Initializes area member. Defualt constructor— Empty body calcArea. This function should be a incomplete function.Next, define a class named Triangle . It should be child of Shape class. It should have the following members:Protected Member Variables: base, a integer used to hold the base of triangle.Height, a integer used to hold the height of the triangle. Public Member Functions: constructor—Initializes values for base, height.

The class’s purpose is to store a value that represents a number of work hours and convert it to a number of days. For example, 8 hours would be converted to 1 day, 12 hours would be converted to 1.5 days, and 18 hours would be converted to 2.25 days. The class should have a constructor that accepts a number of hours, as well as member functions for storing and retrieving the hours and days. The class should also have the following overloaded operators: • (+) Addition operator. When two NumDays objects are added together, the over- loaded + operator should return the sum of the two objects’ hours members. • (-) Subtraction operator. When one NumDays object is subtracted from another, the overloaded − operator should return the difference of the two objects’ hours members. Part 2: Design a class named TimeOff. The purpose of the class is to track an employee’s sick leave, vacation, and unpaid time off. It should have, as members, the…arrow_forward
