C语言中的fillellipse（）函数-yiteyi-C++库

头文件显示图形。h包含 fillellipse（） 函数，用于绘制和填充中心位于（x，y）和（x_半径，y_半径）的椭圆，作为椭圆的x和y半径。 语法：

null

void fillellipse(int x, int y, int x_radius,
                              int y_radius);

where,
(x, y) is center of the ellipse.
(x_radius, y_radius) are x and y 
radius of ellipse.

例如：

Input : x = 200, y = 200,
        x_radius = 50, y_radius = 90
Output : 

Input : x = 300, y = 250,
        x_radius = 100, y_radius = 70
Output :

下面是fillellipse（）函数的实现：

                     // C Implementation for fillellipse()                   
                     #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(&gd, &gm,                               ""                               );                   
                             
                                         // fillellipse function                   
                                         fillellipse(200, 200, 50, 90);                   
                             
                                         getch();                   
                             
                                         // closegraph function closes the
