Question

c语言:输入10个点的坐标（设坐标为整数值），输出距原点最远的点（设唯一）的坐标及该点距原点的距离

Answer 1

#include <stdio.h>
#include <math.h>
int main()
{
    int x,y,l, max=-1, maxx, maxy;
    int i;
    for(i = 0; i < 10; i ++)
    {
        scanf("%d%d",&x,&y);
        l = x*x+y*y;
        if(max < l)
        {
            max = l;
            maxx=x;
            maxy=y;
        }
    }
    
    printf("%d %d %lf\n", maxx, maxy, sqrt(max));
    
    return 0;
}
