這兩種是不是都是對的？都能得到同樣的結果，有沒有什么區別？
#include <stdio.h>
int main()
{
??? int 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;???
}
======================
#include <stdio.h>
int main()
{
??? int x,y;
??? x = 10;
??? y = -3;
??? printf("x+y=%d\n",7???? );?
??? printf("x-y=%d\n", 13??? );
??? printf("x*y=%d\n", -30??? );
??? printf("x/y=%d\n", -3??? );
??? printf("x%y=%d\n", 1??? );?
??? return 0;???
}

習題是讓人體會一下算術運算符的用法。自己把答案算出來，那你讓程序干嘛。
