Question 1: Money dispenser calculator (5 marks)

Write a function that produces the list of NZ notes and coins required to give change for a user-entered amount up to $1000.The amounts are whole dollar amounts (there’s no need for 50c, 20c and 10c coins), so the variables used should be integers.

 

If the amount is $47, you could pay this with 47 $1 coins but you would normally use a selection of larger notes or coins.In your function you are to use the largest possible notes or coins at each step.So for the example of $47 you would recognise that $100 notes are too big and so is a $50 note so you would move down to $20 notes and so on.

 

The function must prompt the user for an amount.This becomes the initial balance and as you dispense notes and coins this balance decreases.For example a function may produce the following output:

Enter the initial amount in dollars: 348

$100

$100

$100

$20

$20

$5

$2

$1

 

A more advanced solution might display something like:

3 x $100

2 x $20

1 x $5

1 x $2

1 x $1

 

Note that either of these solutions is sufficient to obtain full marks for the question.
