How can I swich out int with double or float to produce the right results?

[Rukris]

My program is as follows

#include <stdio.h>
 
int countchange(int q, int d, int n, int p) ;
 
 
/* Don't change the main() function! */
int main () {
   int cents ; 
   int quarters, dimes, nickels, pennies ;
 
   printf("This program will compute the worth of your change.\n\n") ;
   printf("Enter number of quarters you have: ") ;
   scanf("%d", &quarters) ;
   printf("Enter number of dimes you have: ") ;
   scanf("%d", &dimes) ;
   printf("Enter number of nickels you have: ") ;
   scanf("%d", &nickels) ;
   printf("Enter number of pennies you have: ") ;
   scanf("%d", &pennies) ;
 
   cents = countchange(quarters, dimes, nickels, pennies) ;
 
   printf("Your %d quarters, %d dimes, %d nickels and %d pennies",
      quarters, dimes, nickels, pennies) ;
   printf(" are wort %d cents.\n", cents) ;
 
   return 0 ;
}
/* end of main() function */
 
 
 
/* Function countchange
  
   Computes the worth of the given number of quarters,
   dimes, nickels and pennies.
 
*/
 
 
   /* The function */
 
int countchange(int q, int d, int n, int p) {
        int qu;
        int di;
        int ni;
        int pe;
        int cents;
 
                qu = q * .25 ;
                di = d * .1 ;
                ni = n * .05 ;
                pe = p * .01 ;
                                        cents = qu + di + ni + pe ;
 
        return ;
}

When I execute my program I know why I am getting the wrong results because the integer value counts everything that is less than 1 as 0 (basically it rounds) therefore skewing my results. I know double/float will accept decimals but when I try and make qu, di, ni, pe, and cents double/float I still get wrong results.

Any help would be great!

You program claims to output the total number of CENTS, yet you are computing (or trying to compute) DOLLARS.

The total number of cents is just 25*quarters+10*dimes+5*nickels+cents.

Woah thank you so much I didn't even realize that! It works perfectly!
