确定轴平面八分圆的程序

给定 3 个坐标 x、y 和 z，任务是确定轴向平面的八分圆。
例子：

Input: 2, 3, 4
Output: Point lies in 1st octant
Input: -4, 2, -8
Output: Point lies in 6th octant
Input: -6, -2, 8
Output: Point lies in 3rd octant

编程需要懂一点英语

方法：下面给出了确定轴平面八分圆需要检查的条件。

检查是否 x >= 0 且 y >= 0 且 z >= 0，则 Point 位于第一个八分圆。
检查 x < 0 和 y >= 0 和 z >= 0，然后点位于第二个八分圆。
检查是否 x < 0 和 y < 0 且 z >= 0，则 Point 位于第三个八分圆。
检查是否 x >= 0 且 y < 0 且 z >= 0，则 Point 位于第 4 个八分圆。
检查是否 x >= 0 且 y >= 0 且 z < 0，则 Point 位于第 5 个八分圆。
检查是否 x < 0 且 y >= 0 且 z < 0，则 Point 位于第 6 个八分圆。
检查是否 x < 0 且 y < 0 且 z < 0，则 Point 位于第 7 个八分圆。
检查是否 x >= 0 且 y < 0 且 z < 0，则 Point 位于第 8 个八分圆。

下面是上述方法的实现：

// C++ program to print octant
// of a given point.
#include 
#include
 
using namespace std;
 
// Function to print octant
void octant(float x, float y,
                     float z)
{
    if (x >= 0 && y >= 0 && z >= 0)
        cout << "Point lies in 1st octant\n";
          
    else if (x < 0 && y >= 0 && z >= 0)
        cout << "Point lies in 2nd octant\n";
          
    else if (x < 0 && y < 0 && z >= 0)
        cout << "Point lies in 3rd octant\n";
          
    else if (x >= 0 && y < 0 && z >= 0)
        cout << "Point lies in 4th octant\n";
          
    else if (x >= 0 && y >= 0 && z < 0)
        cout << "Point lies in 5th octant\n";
          
    else if (x < 0 && y >= 0 && z < 0)
        cout << "Point lies in 6th octant\n";
          
    else if (x < 0 && y < 0 && z < 0)
        cout << "Point lies in 7th octant\n";
          
    else if (x >= 0 && y < 0 && z < 0)
        cout << "Point lies in 8th octant\n";
}
