Pseudo code for lab 3 – the change calculator program

To determine the steps necessary to solve the problem I usually use real numbers and solve it manually first and keep track of the steps it took to solve the problem. I have included the “real” numbers in blue. They are NOT part of the pseudo code. It is my attempt to show you what I am thinking as I go through the problem solving process.

Step	Variable Needed	Data Type
Get the Total Due from the user and store in numeric variable (Floating Point) Imagine $7.26	Total Due	Floating Point
Get the Amount Paid form the user and store in a numeric variable (Floating Point) Imagine $10	Amount Paid	Floating Point
Calculate Change Due by Subtracting Total Due from Amount Paid, store result in numeric variable (Floating Point) 2.74	Change Due	Floating Point
Calculate the Amount of Change in Cents by multiplying Change Due by 100, store result in a numeric variable (integer). 274	Amount of Change in Cents	Integer capable of holding a very large number. $35 * 100 = 35,000
Determine the Number Of Dollars by dividing the Amount of Change in Cents (274) by 100 and ignoring the remainder, store result in integer variable. 2	Number of Dollars	Integer
Determine the Amount of Change in Cents remaining by dividing Amount of Change in Cents (274) by 100 and storing the remainder back in Amount of Change in Cents. 74
Determine the Number Of Quarters by dividing the Amount of Change in Cents (74) by 25 and ignoring the remainder, store result in integer variable. 2	Number of Quarters	Integer
Determine the Amount of Change in Cents remaining by dividing Amount of Change (74) in Cents by 25 and storing the remainder back in Number of Cents. 24
Determine the Number Of Dimes by dividing the Amount of Change in Cents (24) by 10 and ignoring the remainder, store result in integer variable 2	Number of Dimes	Integer
Determine the Amount of Change in Cents remaining by dividing Amount of Change (24) in Cents by 10 and storing the remainder back in Number of Cents. 4
Determine the Number Of Nickels by dividing Amount of Change in Cents (4) by 5 and ignoring the remainder, store result in integer variable 0	Number of Nickels	Integer
Determine the Amount of Change in Cents remaining by dividing Amount of Change (4) in Cents by 5 and storing the remainder back in Number of Cents. 4 This is the number of pennies
