#include<stdio.h>
int main()
{
	int x,y;
	char c;
	scanf("%d%d %c",&x,&y,&c);
	switch (c){
	case '+':printf("%d",x+y);break;
	case '-':printf("%d",x-y);break;
	case '*':printf("%d",x*y);break;
	case '/':
		if(y==0) printf("Divided by zero!");
	printf("%d",x/y);break;
	default:printf("Invalid operator!");
	}
	return 0;
}

在自己的编译器可以运行，提交会RE，应该怎么处理，谢谢
