C中的扇形（）函数-yiteyi-C++库

头文件显示图形。h包含扇形（）函数，该函数绘制并填充一个椭圆形饼图切片，其中（x，y）为圆心，（s_角，e_角）为起始角和结束角，（x_半径，y_半径）为扇形的x和y半径。 语法：

null

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.

例如：

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 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
