Question

Overview

This checkpoint is intended to help you practice the syntax of operator overloading with member functions in C++. You will work with the same money class that you did in Checkpoint A, implementing a few more operators.

Instructions

1. Begin with a working (but simplistic) implementation of a Money class that contains integer values for dollars and cents.

Here is my code:

/*********************

* File: check12b.cpp

*********************/

#include

using namespace std;

#include "money.h"

/****************************************************************

* Function: main

* Purpose: Test the money class and practice operators

****************************************************************/

int main()

{

   Money account1;

   Money account2;

   // Get the input from the user

   account1.prompt();

   account2.prompt();

   cout << endl;

   cout << "The original values are: ";

   account1.display();

   cout << " and ";

   account2.display();

   cout << endl;

   // TODO: Add code here to add account2 onto account1 using the += operator

   cout << "After doing account1 += account2, the value of account1 is: ";

   account1.display();

   cout << endl;

   Money account3;

   // TODO: Add code here to add account1 and account2 together

   // and put the result in account3

   cout << "From account1 + account2, the value of account3 is: ";

   account3.display();

   cout << endl;

   // TODO: Add code here to apply the ++ pre-increment operator to account1;

   cout << "After ++account1, the value of account1 is: ";

   account1.display();

   cout << endl;

   return 0;

}

{

      dollars += cents / 100;

      cents = cents % 100;

   }

   // These could be done in a smarter way to add cents to dollars if more than 100 etc.

   // but we're trying to keep it simple for this assignment...

   void setDollars(int dollars) { this->dollars = dollars; }

   void setCents(int cents) { this->cents = cents; }

2. This class has the following class diagram:

Money

-dollars : int

-cents : int

+Money()

+Money(dollars, cents)

+getDollars() : int

+getCents() : int

+setDollars(int) : void

+setCents(int) : void

+prompt() : void

+display() : void

-handleOverflow() : void

3. You need to overload the following operators as member functions (in other words methods contained inside the class). This means that you should put the prototypes in your class in the Money.h file, and the bodies of these functions should be in the Money.cpp file.
4. Assuming two Money objects, m1 and m2, implement the following:
   • m1 + m2 (Addition) - Add the dollars and cents of two money objects and return a new one.
   • m1 += m2 (Add onto) - Add the dollars and cents of the item on the right (the parameter) to the item of the left (the current object) and return a reference to it.
   • ++m1 (Pre-increment) - Add one cent to the provided money object (and return a reference to the current object).
5. Note that if the value of cents ever exceeds 100, that amount should roll over into the dollars. There is a function handleOverflow() provided for you that contains this logic. You should call it where appropriate.
6. Fill in the main function (in check12b.cpp) to use your operators as noted.

Sample Output

The following is an example of output for this program:

Dollars: 10

Cents: 67

Dollars: 11

Cents: 67

¶

The original values are: $10.67 and $11.67

After doing account1 += account2, the value of account1 is: $22.34 From account1 + account2, the value of account3 is: $34.01 After ++account1, the value of account1 is: $22.35

Another example would be:

Dollars: 10

Cents: 85

Dollars: 1

Cents: 14

¶

The original values are: $10.85 and $1.14

After doing account1 += account2, the value of account1 is: $11.99 From account1 + account2, the value of account3 is: $13.13 After ++account1, the value of account1 is: $12.00
