说是必须在else后加个;我加了后可以运行了，但是结果不对

Question

#include <stdio.h>
int main( )
{
float x,y;
printf("输入x和y的值：");
scanf("%.2f%.2f",&x,&y);
if(x>0 && y>0)
printf("(%.2f,%.2f)在第一象限!\n",x,y);
else if(x==0)
printf("(%.2f,%.2f)在y轴上！\n",x,y);
else if(x>0 && y<0)
printf("(%.2f,%.2f)在第四象限!\n",x,y);
else if(x<0 && y>0)
printf("(%.2f,%.2f)在第二象限上!\n",x,y);
else if(x<0 && y<0)
printf("(%.2f,%.2f)在第三象限上!\n",x,y);
else (y==0)
printf("(%.2f,%.2f)在x轴上!\n",x,y);
}

Answer 1

else (y==0)
应该是else if(y==0) 啊
scanf("%.2f%.2f",&x,&y);
改为
scanf("%f%f",&x,&y);
