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 :
C
Output :
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;
