The header file graphics.h contains circle() function which draws a circle with center at (x, y) and given radius.
Syntax :
circle(x, y, radius); where, (x, y) is center of the circle. 'radius' is the Radius of the circle.
Examples :
Input : x = 250, y = 200, radius = 50 Output : Input : x = 300, y = 150, radius = 90 Output :
Below is the implementation to draw circle in C:
// C Implementation for drawing circle #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, "" );
// circle function
circle(250, 200, 50);
getch();
// closegraph function closes the
// graphics mode and deallocates
// all memory allocated by
// graphics system .
closegraph();
return 0;
