本题的详尽解析

jimmyzzxhlh 网友已经贴了一份解答,我的想法与他稍有不同,但最后推出的公式是一样的:

我并没有从The Money customer gets = The money James lost这方面来想,而是:

(卖价)M + (找给顾客的钱)C = 收到的钱

收到的钱 - (假币)P - (成本)N - (找给顾客的钱)C = 商人赚到的钱

因此,商人赚到的钱 = M + C - P - N - C = M - P - N

由于题目要求的是商人损失的钱,只要取相反数即可: P + N - M

由于这题的编程难度跟A+B没什么区别,所以我贴代码应该不会有人有意见的~哈哈,满足一下贴码欲。

参考代码(C++)

#include <stdio.h>

int main()
{
	int n,m,p,c;
	scanf("%d%d%d%d",&n,&m,&p,&c);
	while((n|m|p|c)!=0)
	{
		printf("%d\n",n+p-m);
		scanf("%d%d%d%d",&n,&m,&p,&c);
	}
	return 0;
}
