sector() function in C

The header file graphics.h contains sector() function which draws and fills an elliptical pie slice with (x, y) as center, (s_angle, e_angle) as starting and ending angle and (x_radius, y_radius) as x and y radius of sector.
Syntax :

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.

Examples :

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 : 

Below is the implementation of sector() function :

// 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 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;
}

Output :
