Question

5.19 LAB: Exact change - functions
Write a program with total change amount as an integer input that outputs 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.

Ex: If the input is:

0
or less, the output is:

no change
Ex: If the input is:

45
the output is:

1 quarter
2 dimes
Your program must define and call the following function. The function exact_change() should return num_dollars, num_quarters, num_dimes, num_nickels, and num_pennies.
def exact_change(user_total)

Answer 1

Answer:

def exact_change(user_total):

    if user_total <=0:

         print("No change")

    else:

         num_dollars = int(user_total/100)

         user_total = user_total % 100

         num_quarters= int(user_total/25)

         user_total = user_total % 25

         num_dimes= int(user_total/10)

         user_total = user_total % 10

         num_nickels= int(user_total/5)

         num_pennies= user_total % 5

         if num_dollars >= 1:

              if num_dollars == 1:

                   print(str(num_dollars)+" num_dollars")

              else:

                   print(str(num_dollars)+" amountdollars")

         if num_quarters>= 1:

              if num_quarters== 1:

                   print(str(num_quarters)+" quarter")

              else:

                   print(str(num_quarters)+" quarters")

         if num_dimes>= 1:

              if num_dimes== 1:

                   print(str(num_dimes)+" dime")

              else:

                   print(str(num_dimes)+" dimes")

         if num_nickels>= 1:

              if num_nickels== 1:

                   print(str(num_nickels)+" nickel")

              else:

                   print(str(num_nickels)+" nickels")

         if num_pennies>= 1:

              if num_pennies== 1:

                   print(str(num_pennies)+" penny")

              else:

                   print(str(num_pennies)+" pennies")

           

user_total = int(input("Enter user_total Here:  "))

exact_change(user_total)

The explanation is long. So, I added it as an attachment.

Answer 2

Answer:

Written in Python:

def exact_change(user_total):

   num_dollars = user_total // 100 #convert to dollars

   user_total %= 100 #get remainder after conversion

   num_quarters = user_total // 25 #convert to quarters

   user_total %= 25 #get remainder after conversion

   num_dimes = user_total // 10 #convert to dimes

   user_total %= 10 #get remainder after conversion

   num_nickels = user_total // 5 #convert to nickels

   user_total %= 5 #get remainder after conversion

   num_pennies = user_total

   return(num_dollars, num_quarters, num_dimes, num_nickels, num_pennies)

if __name__ == '__main__':

   input_val = int(input()) #prompt user to input an integer

   num_dollars, num_quarters, num_dimes, num_nickels, num_pennies = exact_change(input_val) #recall exact_change function

   

   #define output statements to output number of exact_change variables:  

   #num_dollars, num_quarters, num_dimes, num_nickels, num_pennies  

   if input_val <=0: #if amount is zero

       print('no change') #print output

       

   else:

       if num_dollars > 1: #if number of dollars is greater than one

           print('%d dollars' % num_dollars) #print number of dollars

       elif num_dollars == 1: # if number of dollars equal 1

           print('%d dollar' % num_dollars) #print dollar in singular

       

       if num_quarters > 1: #if number of quarters is greater than one

           print('%d quarters' % num_quarters) #print number of quarters

       elif num_quarters ==1: # if number of quarters equal 1

           print('%d quarter' % num_quarters) #print quarter in singular

       

       if num_dimes > 1: #if number of dimes is greater than one

           print('%d dimes' % num_dimes) #print number of dimes

       elif num_dimes == 1: # if number of dimes equal 1

           print('%d dime' % num_dimes) #print dime in singular

           

       if num_nickels > 1: #if number of nickels is greater than one

           print('%d nickels' % num_nickels) #print number of nickels

       elif num_nickels == 1: # if number of nickels equal 1

           print('%d nickel' % num_nickels) #print nickel in singular

       

       if num_pennies >1: #if number pennies is greater than one

           print('%d pennies' % num_pennies) #print number of pennies

       elif num_pennies ==1: # if number of pennies equal 1

           print('%d penny' % num_pennies) #print penny in singular

It's really long, but it's necessary to get all the correct answers.
