C program to calculate change -

i trying write program calculate change, doesn't seem work. think problem owed 1/ paid 1; when tried print there values got nothing (0). ?

#include <stdio.h>  int main() { double owed, paid; int  dollars, quarters, dimes, nickels, cents, remainder, owed1, paid1; printf("how did customer have pay ?\n"); scanf("%f",&owed);  printf("how did customer pay ?\n"); scanf("%f",&paid);  owed1 = owed * 100;   paid1 = paid * 100; int change = paid1 - owed1; dollars =  change / 100; remainder = change % 100; quarters = remainder / 25; remainder = remainder % 25; dimes = remainder / 10; remainder = remainder % 10; nickels = remainder / 5; remainder = remainder % 5; cents = remainder; printf("%d",dollars); printf("dollars:%d, quarters:%d, dimes:%d, nickels:%d, cents:%d", dollars , quarters , dimes , nickels , cents ); return 0; } 

you're using %f in scanf, format specifier float, variables doubles. should use %lf instead:

scanf("%lf",&owed);  

same thing paid. should getting warning compiler that.
