Question

Describe how you would create a Python program that calculates the exact amount of change to give a customer in denominations of quarters, dimes, nickels, and pennies. For example, if the change is 79 cents, how many of each coin would be needed to give change?

Answer 1

As we know :

• 1 quarter = 25 cents
• 1 dimes = 10 cents
• 1 nickels = 5 cents
• 1 penny = 1 cent

So if we divide the change by -

• 25 we get no. of quarters
• 10 we get no. of dimes
• 5 we get no. of nickels
• 1 we get no. of pennies

In python, we will use the modulo operator to achieve this -

//(Floor division operator) = Divides and returns the integer value of the quotient. It-dumps the digits after the decimal.

%(modulo) = Divides and returns the value of the remainder.

#to get the input from the user
c=int(input('Please enter an amount between 0-99:\n'))
# //(Floor division operator) = Divides and returns the integer value of the quotient.
# It-dumps the digits after the decimal. 
# %(modulo) = Divides and returns the value of the remainder.
print(c//25, "quarters")
c = c%25
print(c//10, "dimes")
c = c%10
print(c//5, "nickles")
c = c%5
print(c//1, "pennies")
