程序输出结果不对啊

Enter the numbers of points: 3
Enter 3 points: 1 1 4 -3 4 9
The closest two points are (1.0,1.0) and (1.0,1.0)

你的 int p1 = 0, p2 = 0; double shortestDistance = distance(points[p1][0], points[p1][1], points[p2][0], points[p2][1]); 你p1=p2=0 然后shortestDistance得出的值是0 你觉得你下面在怎么算能算出小于0的值？最总结果肯定就是 （1，1）

int p1 = 0, p2 = 1;

那个shortestDistance变成求自身的，所以是最短距离了。要控制程序比较的是两个不同的点坐标

谢谢楼上各位，看到错误啦！！！
