# Splitting money.

Hello,
i want to make this program but i dont knwo where to begin ...

the program should ask for an amount (money) en then it should give me the given amount  in the shortest possible way

for example : 105,20 euro

the program should say
1X 100
1x 5
1 x 20 cent

here is what i have already

``````using System;

Looks OK - whats the issue?

Something like this might work:

private string GetCurrency(double Amount)
{
if (Amount == 0) {
return "";
}
if (Amount / 100 > 1) {
return string.Format("{0}x100{1}{2}", Convert.ToInt32(Amount / 100), Constants.vbCrLf, GetCurrency(Amount % 100));
} else if (Amount / 10 > 1) {
return string.Format("{0}x10{1}{2}", Convert.ToInt32(Amount / 10), Constants.vbCrLf, GetCurrency(Amount % 10));
} else if (Amount > 1) {
return string.Format("{0}x1{1}{2}", Convert.ToInt32(Amount), Constants.vbCrLf, GetCurrency(Amount % 1));
} else if (Amount > 0.19) {
return string.Format("{0}x20 cent{1}{2}", Convert.ToInt32(Amount / 0.19), Constants.vbCrLf, GetCurrency(Amount % 0.19));
} else {
return Convert.ToInt32(Amount * 100).ToString() + "x01";
}
}

Sounds like a special case of this problem:

http://projecteuler.net/problem=31

You want loops for each amount of each coin that will satisfy the answer and store the number of coins.

Taking the above link as an example:

200 pence would require these loops:

0-1 x 200 pence
0-2 x 100 pence
0-4 x 50 pence
.
.
.
0-200 1 pence

You then just need to output all permutations that have the minimum coin quantity.

Thanks , now i have something like this , but i get this error when i try to do this line of code
``````while (Bedrag >= 0.50) {

Modulus doesn't work with integers.
I think you need something like this (for your homework!?):

``````using System;

decimal kopie = Bedrag;
decimal geld;
geld = 500;
while (Bedrag >= geld) {
Nr500++;
Bedrag = Bedrag - geld;
}
geld = 200;
while (Bedrag >= geld) {
Nr200++;
Bedrag = Bedrag - geld;
}
geld = 100;

Bedrag = Bedrag - geld;
