哪里运行错误了?
#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;
}
运行成功,输出错误
hello.c: In function 'main':
hello.c:11:15: warning: unknown conversion type character 'y' in format [-Wformat=]
printf("x%y=%d\n",x%y );
^
x+y=7
x-y=13
x*y=-30
x/y=-3
