Can someone help me do this program???

The program reads a whole change amount in dollars and prints how many 500 dollars bills,200 dollars bills,100 dollars bills ,50 dollars bills ,20 dollars bills ,10 dollars bills 5 dollars bills ,and 1 dollars coins should the cashier return to the customer.
for example,if the cashier enters 2789 dollars,the program should print:
amount entered:2789 dollars
5-500 dollars bills
1-200 dollars bills
1-50 dollars bills
1-20 dollars bills
1-10 dollars bills
1-5 dollars bills
4-1 dollars coins

the program should read many positive values and calculate the change for each one. the program should stop when you enter a 0 or a negative value
I want to use function, array and loop.

I will appreciate your help.

Post what you have tried so far.

Basically what you need to do is divide by 500, take the remainder of that with the modulus operator, divide by 200, take the remainder of that, divide by 50, and so on. As for stopping at 0, or a negative number, you could use something like this:

(Toggle Plain Text)

int x;
scanf("%d", &x);

for(x;x>0;)
{
     printf("You need %d 500-dollar bills", x/500);
     x = x % 500;
     printf("You need %d 200-dollar bills", x/200);
     x = x % 500

     /* code the rest of it*/

     scanf("%d", &x);
}

I did not know you could get a negative number with modulus.

Sara, show us what you have done so far... and where you are having errors. I would hate to do the assign for you, as you will not learn anything and it will do more harm than good. Mjordan2nd is right in regards to the use of the modulus operator.
