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 :
