Question

How to divide a given amount into different bills (banknote) and coins in C

Answer 1

#include <stdio.h>

int main(void) {
    int bills_coins[9] = {1000, 500, 100, 50, 20, 10, 5, 2, 1};
    int amount = 9725;
    
    int tmp = amount;
    for (int i = 0; i < 9; i++) {
 	    printf("%d = %d\n", bills_coins[i], tmp / bills_coins[i]);
 	    tmp = tmp % bills_coins[i];
    }

    return 0;
}





/*
run:

1000 = 9
500 = 1
100 = 2
50 = 0
20 = 1
10 = 0
5 = 1
2 = 0
1 = 0
