C中的ector()函数

头文件graphics.h包含扇区()函数，该函数绘制和填充以(x，y)为中心，(s_angle，e_angle)为起始和结束角度以及(x_radius，y_radius)为x和y半径的椭圆形饼图部门。
句法 ：

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 ：

输入：x = 200，y = 200，s_angle = 0，e_angle = 150，x_radius = 50，y_radius = 65输出： 输入：x = 200，y = 200，s_angle = 30，e_angle = 120，x_radius = 90，y_radius = 85输出：

下面是ector()函数：

// C Implementation for sector()
#include 
  
// 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;
}
