开心一下-换汽水问题

10块买5瓶汽水，5瓶汽水5个盖子5个空瓶。。。
好麻烦，写个程序吧

#include <iostream>

/* run this program using the console pauser or add your own getch, system("pause") or input loop */

int main(int argc, char** argv) {

int bottle=0,bottle_cap=0,empty_bottle=0;
int num=0,money=0;
printf("Please input your money :\n");

while(scanf("%d",&money)==1)
{
printf("Now the money you have is %d $!\n",money);
bottle = money/2;
int temp=0,temp_cap=0,temp_empty=0;

bottle_cap = bottle;//5个盖
empty_bottle = bottle;//5个瓶子
num += bottle;//喝了5瓶

while(bottle_cap/4 >0 || empty_bottle/2>0)
{
//处理瓶盖 bottle_cap
temp_cap += bottle_cap/4;
bottle_cap=bottle_cap%4;
temp_empty += empty_bottle/2;
empty_bottle=empty_bottle%2;
temp = (temp_empty+temp_cap);
num += temp;

empty_bottle += temp;
bottle_cap += temp;

temp_cap = 0;
temp_empty = 0;
temp=0;
}
printf("According to your money...\n");
printf("you can buy %d bottles'drink\n",num);
num = 0;
}
return 0;
}
