Consider the classes class cashRegister and dispenserType given in the Programming Example “Juice Machine” in Chapter 10. Write a program to test the classes designed in parts 20a and 20b.

Define the class bankAccount to implement the basic properties of a bank account. An object of this class should store the following data: Account holder’s name (string), account number (int), account type (string, checking/saving), balance (double), and interest rate (double). (Store interest rate as a decimal number.) Add appropriate member functions to manipulate an object. Use a static member in the class to automatically assign account numbers. Also declare an array of 10 components of type bankAccount to process up to 10 customers and write a program to illustrate how to use your class.

1. The class boxType is defined by extending the definition of the class rectangleType. In this exercise, derive the class boxType from the class rectangleType, add the functions to overload the operators +, -, *, ==, !=, <=, <, >=, >, and pre- and post-increment and decrement operators as members of the class boxType. Also overload the operators << and >>. Overload the relational operators by considering the volume of the boxes. For example, two boxes are the same if they have the same volume.

2. Write the definitions of the functions of the class boxType as defined in part (1).

3. Write a test program that tests various operations on the class rectangleType.

a. Redo Programming Exercise 1 by overloading the operators as nonmembers of the class rectangleType. b. Write a test program that tests various operations on the class rectangleType.

In previous chapter, the class dateType was designed to implement the date in a program, but the member function setDate``` and the constructor do not check whether the date is valid before storing the date in the member variables. Rewrite the definitions of the function setDate`` and the constructor so that the values for the month, day, and year are checked before storing the date into the member variables. Add a member function, isLeapYear, to check whether a year is a leap year. Moreover, write a test program to test your class.

Chapter 9 defined the struct studentType to implement the basic properties of a student. Define the class studentType with the same components as the struct studentType, and add member functions to manipulate the data members. (Note that the data members of the class studentType must be private.) Write a program to illustrate how to use the class studentType.

Consider the classes class cashRegister and dispenserType given in the Programming Example “Juice Machine” in Chapter 10. The class dispenserType, in the Programming Example “Juice Machine” in Chapter 10, is designed to implement a dispenser to hold and release products. In this class, add the functions to overload the increment and decrement operators to increment and decrement the number of items by one, respectively, and the stream insertion operator for easy output.

In this chapter, the class dateType was designed to implement the date in a program, but the member function **setDate **and the constructor do not check whether the date is valid before storing the date in the member variables. Rewrite the definitions of the function **setDate **and the constructor so that the values for the month, day, and year are checked before storing the date into the member variables. Add a member function, isLeapYear, to check whether a year is a leap year. Moreover, write a test program to test your class.

A firm is considering two mutually exclusive projects, X and Y, with the following cash flows:

The projects are equally risky, and their WACC is$12 \%$. What is the MIRR of the project that maximizes shareholder value?

Solve the matrix games using a geometric linear programming approach.

$$\left[\begin{array}{rr}{2} & {-3} \\ {-1} & {2}\end{array}\right]$$

Chapter 9 defined the struct studentType to implement the basic properties of a student. Define the class studentType with the same components as the struct studentType, and add member functions to manipulate the data members. (Note that the data members of the class studentType must be private.) Write a program to illustrate how to use the class studentType.

Suppose an exception is thrown in a function. What are the three things the function can do?

Which catch block catches all types of exceptions? (3)

Find the error(s) in the following code:

class mystery // Line 1
{             // Line 2
    friend mystery operator+(const mystery &a,
                             const mystery &b) const; // Line 3
    // Returns the object containing the sum of
    // corresponding members of objects a and b.
        .

        .
private :           // Line 4
     double r; // Line 5
