Chapter 5, Problem 5.32E

Program Plan Intro

Program Plan:

1. Include Header files.
2. Declare class DollarAmount.

• Start declaring public member functions.
• Declare “DollarAmount(int64_t value)” constructor which puts pennies in variable “amount”.
• Declare “DollarAmount(int64_t value1, int64_t value2)” constructor which takes two arguments to take value in dollars and cents. These are then converted to pennies and transferred to variable “amount”.
• Define function add to add amount to variable “amount”.
• Define function to subtract an amount from variable “amount”.
• Define member function "divide" to divide "amount" with an argument "d" passed in the function using rounding technique used in addInterest member function.
• Define function addInterest to calculate interest on variable “amount”.

• Use conditional operator to pass value to constructor of class, calculating value using Banker’s rounding.
• Define function "toString()" to return a string representation of a DollarAmount object for display purpose.
• Declare private members:

amount to store dollar amount in pennies.

3. End of class.
4. Start the main function

• Declare two objects of class DollarAmount "d1" and "d2" by passing amount in pennies, which will invoke single argument constructor;
• Display result of adding amount of d2 to d1 using "add" function modifying object d1.
• Display result of subtracting amount of d2 from d1 using "subtract" function modifying object d1.
• Display result of subtracting amount of d1 from d2 using "subtract" function modifying object d2.
• Ask for the interest rate and divisor in "rate" and "divisor".
• Create object "balance" of class DollarAmount with initial balance 100000.
• Display initial balance of "balance" object.
• Display headers of the table as "Interest Year Amount on deposit"
• Use for loop to run for 10 years

• Call function addInterest using "balance" object, with "rate" and "divisor"
• Display values of Interest Year and balance amount
• End of for loop
• End of main function
