我想半天了 就是不知道为什么不执行语句 求帮助
#include<stdio.h>int main()
{
int x,y,t,a,b;
scanf("%f,%f",&x,&y);
if (x<0) x=-x;
if (y<0) y=-y;
a=(x-2)*(x-2);
b=(y-2)*(y-2);
t=sqrt(a*b);
if(0<t<=1) {printf("the height of the bulding is 10 meters");}
else printf("the height of the bulding is 0 meters");}
不管输入什么数字 结果都是the height of the bulding is 10 meters
求高人指点
