fillellipse() function in C

The header file graphics.h contains fillellipse() function which draws and fills an ellipse with center at (x, y) and (x_radius, y_radius) as x and y radius of ellipse.
Syntax :

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.

Examples :

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

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

Below is the implementation of fillellipse() function :

// 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 initializes the
    // graphics system by loading a
    // graphics driver from disk
    initgraph(&gd, &gm, "");

    // fillellipse function
    fillellipse(200, 200, 50, 90);

    getch();

    // closegraph function closes the
    // graphics mode and deallocates
    // all memory allocated by
    // graphics system .
    closegraph();

    return 0;
}

Output :
