? printf("x%%y=%d\n",?? x%y? );
y前面需要加一個% ，因為%y被當作特殊字符了（參考%d）

#include <stdio.h>
int main()
{
??? int x,y;
??? x = 10;
??? y = -3;
??? printf("x+y=%d\n",? x+y?? );?
??? printf("x-y=%d\n",? x-y?? );
??? printf("x*y=%d\n",?? x*y? );
??? printf("x/y=%d\n",? x/y?? );
??? printf("x%%y=%d\n",?? x%y? );?
??? return 0;???
