WA里说的是第一行错了但是我不知道错在哪求各位帮忙看看谢谢了

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