4. 15 Exact change (College level not sure why it says middle school)

Write a program with total change amount as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies.

In python:

def print_change(total_change):#this is also total cents, because integers don't have decimal points, so I can't use dollars as my unit

dollars = int(total_change / 100)

remaining_change = total_change - dollars * 100

quarters = int(remaining_change / 25)

remaining_change -= quarters * 25

dimes = int(remaining_change / 10)

remaining_change -= dimes * 10

nickels = int(remaining_change / 5)

remaining_change -= nickels * 5

pennies = remaining_change

all = {'dollar': dollars, 'quarter': quarters, 'dime': dimes, 'nickel': nickels, 'penny': pennies}

for num in [0, 1, 2, 3, 4]:

coin_type = list(all.keys())[num]

amount = all[coin_type]

if num < 4 and amount > 1 or amount == 0 and num < 4:

coin_type += 's'

elif num == 4 and amount > 1 or amount == 0 and num == 4:

coin_type = 'pennies'

print('\n', amount, coin_type)

while True:

total_change = int(input()) #in cents

print_change(total_change)

Had fun making this one... hope it helps. :)
