确定轴向平面八分圆的程序

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

方法：下面给出了确定轴向平面的八分圆需要检查的条件。

• 检查x> = 0且y> = 0且z> = 0，则Point位于第一个八进制数。
• 检验x <0且y> = 0且z> = 0，则Point位于第二个八分圆。
• 检查x <0和y <0以及z> = 0，则Point位于第三个八分位。
• 检查x> = 0且y <0和z> = 0，则Point位于第4个八分圆。
• 检查x> = 0且y> = 0且z <0，则Point位于第5个八分圆。
• 检查x <0且y> = 0且z <0，则Point位于第6个八分圆。
• 检查x <0和y <0以及z <0，则Point位于第7个八分位。
• 检查x> = 0且y <0和z <0，则Point位于第8个八分圆。

下面是上述方法的实现：

C++

// 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";

        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";
}
