The header file graphics.h contains arc() function which draws an arc with center at (x, y) and given radius. start_angle is the starting point of angle and end_angle is the ending point of the angle. The value of the angle can vary from 0 to 360 degree.
Syntax :
void arc(int x, int y, int start_angle, int end_angle, int radius); where, (x, y) is the center of the arc. start_angle is the starting angle and end_angle is the ending angle. 'radius' is the Radius of the arc.
Examples :
Input : x=250, y=250, start_angle = 155, end_angle = 300, radius = 100 Output :Input : x=250, y=250, start_angle = 0, end_angle = 300, radius = 100; Output :
Below is the implementation of arc() function :
// C implementation of arc function #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;
// location of the arc
int x = 250;
int y = 250;
// starting angle and ending angle
// of the arc
int start_angle = 155;
int end_angle = 300;
// radius of the arc
int radius = 100;
// initgraph initializes the graphics system
// by loading a graphics driver from disk
initgraph(&gd, &gm, "" );
// arc function
arc(x, y, start_angle, end_angle, radius);
getch();
// closegraph function closes the graphics
// mode and deallocates all memory allocated
// by graphics system
closegraph();
return 0;
