C语言 sector()用法及代码示例

头文件graphics.h包含sector()函数，该函数绘制并填充以(x，y)为中心，(s_angle，e_angle)为起始和结束角以及(x_radius，y_radius)为x和y半径的椭圆形饼图。
用法:

void sector(int x, int y, int s_angle, 
           int e_angle, int x_radius, 
                        int y_radius);

where,
(x, y) is center of the sector.
(s_angle, e_angle) are starting 
and ending angles.
(x_radius, y_radius) are x and y
radius of sector.

例子：

Input:x = 200, y = 200, s_angle = 0,
         e_angle = 150, x_radius = 50, 
         y_radius = 65
Output:

Input:x = 200, y = 200, s_angle = 30, 
        e_angle = 120, x_radius = 90, 
        y_radius = 85 
Output:

下面是sector()函数的实现：

// C Implementation for sector() 
#include <graphics.h> 
  
// driver code 
int main() 
{ 
    // gm is Graphics mode which is 
    // a computer display mode that 
    // generates image using pixels. 
    // DETECT is a macro defined in 
    // "graphics.h" header file 
    int gd = DETECT, gm; 
  
    // initgraph initializes the 
    // graphics system by loading a 
    // graphics driver from disk 
    initgraph(&gd, &gm, ""); 
  
    // sector function 
    sector(200, 200, 0, 150, 50, 65); 
  
    getch(); 
  
    // closegraph function closes the 
    // graphics mode and deallocates 
    // all memory allocated by 
    // graphics system . 
    closegraph(); 
  
    return 0; 
}

输出：
