Latte no sugar

用do while 寫;

#include<stdio.h>

#include<stdlib.h>

int main(){

int pay , change , change1 , change2 , change3;
int coin , coin1 , coin2 , coin3 , k;
coin = 50;
coin1 = 10;
coin2 = 5;
coin3 = 1;

do{
printf("How much to pay:");
scanf("%d" , &pay);

change = pay / coin;
printf("50 coin has %d\n",change);

change1 = (pay%coin) / coin1;
printf("10 coin has %d\n",change1);

change2 = (pay%coin1) / coin2;
printf("5 coin has %d\n",change2);

change3 = (pay%coin2) / coin3;
printf("1 coin has %d\n",change3);

k = change + change1 + change2 + change3;
printf("Total coins has %d",k);
printf("\n\n");
}
while(k != 0);
return ;
}

似乎又更快了點
