# Help with codes...

### Question

• I'm working on a problem that states: Write a program to make change for an amount of money 0 through 99 cents input by the user. The output of the program should show the number of coins from each denomination used to make change.

I've already created my form, I'm just unsure of what codes to use to make the program run efficiently. Can anyone help?

• I suggest you start by thinking of you you would make change in the real world, then try to write code that does the same thing. If you have to give someone 88 cents in change, how many quarters would you need? How did you come up with that number (try to think of a general method rather than one that only works for 88 cents)? Next, how would you decide how many dimes.

• Is this a school-related question?
First write out an algorythm on paper. try this a few times till you come at something that looks right, next translate this in coding, it might take a few times but you'll find it eventually.

Hi,

You could take a look at my code in this thread:>>

it has code which would show you the change given a certain amount.

You could maybe adapt that code to suit your question here.  :)

• I agree with the gents above. This sounds like a school problem, and while there aren't rules against helping with school projects (not on the forums anyway, rules from your teacher? That's another story...) it would probably be best for you to work things out yourself.

As others said, try to reason through it. In the real world, you would start with the biggest coin and work your way down to the smaller ones. How many quarters can I give without going over the amount? Okay, now how many dimes can I give? Okay, now nickles, and pennies. Good luck!
