测试样例是1,2 3,3 2,1 ^Z
结果是
Point : (1, 2)
Point : (3, 3)
Point : (2, 1)
Point : (1, 1)
Point : (4, -3)
==========gorgeous separator==========
Point : (1, 0)
Point : (3, 3)
Point : (0, 0)
Point : (4, -3)
Point : (1, 0)
Point : (1, 0)
==========gorgeous separator==========
In total : 66 points.
如何修改使得变成
Point : (1, 2)
Point : (3, 3)
Point : (2, 1)
Point : (1, 1)
Point : (4, -3)
==========gorgeous separator==========
Point[1] : (1, 0)
Point[2] : (3, 3)
Point[3] : (0, 0)
Point[4] : (4, -3)
Point[64] : (1, 0)
Point[64] : (1, 0)
==========gorgeous separator==========
In total : 66 points.
[解决办法]
给show函数加个参数,然后改变打印内容为：
void show(int index)
{
cout<<std::setprecision(16)<<"Point["<<index<<"] : "<<'('<<x1<<c1<<' '<<y1<<')'<<'\n';
}
index就是你的1,2,3,4,64,64
[解决办法]
很考智力

建议楼主写程序的时候加上注释，这样方便别人理解你写的程序
