Question

5.19 LAB: Exact change - functions

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)

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.
