Write a program to fill a circle using flood fill algorithm

#include<conio.h>

#include<graphics.h>

void floodFill(int, int, int, int);

int midx=319, midy=239;

void main()

{

      int gdriver=DETECT, gmode, x,y,r;

      initgraph(&gdriver, &gmode, "c:\\tc\\bgi");

      cleardevice();

      printf("Enter the Center of circle (X,Y) : ");

      scanf("%d %d",&x,&y);

      printf("Enter the Radius of circle R : ");

      scanf("%d",&r);

      circle(midx+x,midy-y,r);

      getch();

      floodFill(midx+x,midy-y,13,0);

      getch();

      closegraph();

}

void floodFill(int x, int y, int fill, int old)

{

      if(getpixel(x,y) == old)

      {

            putpixel(x,y,fill);

            delay(5);

            floodFill(x+1,y,fill,old);

            floodFill(x,y+1,fill,old);
