outputing change in denominations

[rated]

Hi, I have to write a program that will output a receipt showing purchased price, taxes, total, amount paid and change. I did that part.

But what do I have to do so that my program will output the change in denominations (e.g. change is $8.04 - output exact dominations, that is to say, one $5 bill, a toonie, quarters.etc)?
How do I do that using the modulus %operator?

thanks!.

I did this last year. It was pretty complicated. Basically, you find the greatest denomination the total can divide into, use div to find out how many of those bills/coins are needed, then subtract that number times the bill value to get your remainder (you can't use mod here). Then repeat. Very long project.

You can use modulus to tell you right away how much is left.

For example, says you have $8.32
Biggest money denomination would be a 5 dollar bill.

8.32 mod 5 = 3.32
