# Draw Circle using Bresenham’s Circle Algorithm

Write a C Program to Draw Circle using Bresenham’s Circle Algorithm. Here’s simple Program to Draw Circle using Bresenham’s Circle Algorithm in C Programming Language.

Below is the source code for C Program to Draw Circle using Bresenham’s Circle Algorithm which is successfully compiled and run on Windows System to produce desired output as shown below :

## SOURCE CODE : :

```/*  C Program to Draw Circle using Bresenham’s Circle Algorithm  */

#include <stdio.h>
#include <dos.h>
#include <graphics.h>
void plotPoints(int cx, int cy, int x, int y) {
putpixel(cx+x, cy+y, RED);
putpixel(cx-x, cy+y, RED);
putpixel(cx+x, cy-y, RED);
putpixel(cx-x, cy-y, RED);
putpixel(cx+y, cy+x, RED);
putpixel(cx-y, cy+x, RED);
putpixel(cx+y, cy-x, RED);
putpixel(cx-y, cy-x, RED);
}
void main() {
int cx, cy, x = 0, y, r, p;
int gd = DETECT, gm;
clrscr();
printf("Enter the coordinates of centre of the circle: ");
scanf("%d %d", &cx, &cy);
scanf("%d", &r);
y = r;
p = 3 - 2 * r;
initgraph(&gd, &gm, "");
cleardevice();
while (x < y) {
plotPoints(cx, cy, x, y);
x++;
if (p < 0)
p = p + 4 * x + 6; else {
y--;
p = p + 4 * (x - y) + 10;
}
plotPoints(cx, cy, x, y);
delay(200);
}
getch();
}```

Above is the source code for C Program to Draw Circle using Bresenham’s Circle Algorithm which is successfully compiled and run on Windows System.The Output of the program is shown above .
