So basically they are asking me to write a program that calculates the number of bills of 100, 50, 20, 10, 5 to breakdown a quantity entered. But calculates the least quantity of bills of each type to make the quantity entered.

Any help appreciated.

Before I proceed, I would like to thank everyone who greeted me this day. Very well-appreciated. :)

You can learn from it, at the same time, you could build your own understanding from the simple tutorials I've made from it.

Happy Coding! :D

@geralddevera: how about helping the op?

@rgmartino: you will probably want to use the / and % operators to do this. Is it going to be in C or C++?
Also, do you know how to break down $87 by hand?

Yeah, knowing how to do a task is part of making a program do that task.

Let's say the number is 126.

(integer) 126 / 100 = 1
so it's 1 times $100.

126 % 100 = 126 - (126 / 100 * 100) = 126 - (1 * 100) = 126 - 100 = 26

26 / 50 = 0
so it's 0 times $50.

26 % 50 = 26

26 / 20 = 1
so it's 1 times $20.

26 % 20 = 6

6 / 10 = 0
so it's 0 times $10.

6 % 10 = 6

6 / 5 = 1
so it's 1 times $5.

6 % 5 = 1
then we have $1 left over.

So the answer would be one $100 bill, one $20 bill, one $5 bill, and remaining $1. That's sort of the idea, I think.
