3. Write a program that prompts the user to input an integer that represents cents. The program will then calculate the smallest

miss Akunina [59]

Answer:

The program in Python is as follows:

cents = int(input("Cents: "))

qtr = int(cents/25)

cents = cents -qtr * 25

nkl = int(cents/5)

pny = cents -nkl * 5

print(qtr,"quarters,",nkl,"nickels,",pny,"pennies")

Explanation:

This gets input for cents

cents = int(input("Cents: "))

This calculates the quarters in cents

qtr = int(cents/25)

This gets the remaining cents

cents = cents -qtr * 25

This calculates the nickel in remaining cents

nkl = int(cents/5)

This calculates the pennies in remaining cents

pny = cents -nkl * 5

This prints the required output

print(qtr,"quarters,",nkl,"nickels,",pny,"pennies")
