Generating Random circle: using c/c++ and graphics

Hey guys, in this post I am writing very short graphics program. This program generates random circle of random size. You can modify the delay time to see the effect more clearly. Here's the screen shot of the output.

Here's the program. Enjoy coding...

#include<stdio.h>

#include<dos.h>
int main()
{
    int i,j,x=0,y=0;
    int color=0;
    int gd=DETECT, gm;
    initgraph(&gd,&gm,"..\\bgi");
    cleardevice();
    setcolor(0);
    randomize();
    while(!kbhit())
    {
        delay(70);

        color=15-random(1500)%15;
        setcolor(color);
        setfillstyle(1,color);
        x=639-random(90000)%639;
        y=460-random(90000)%460;
        circle(x,y,110-random(1000)%100);
        floodfill(x,y,color);
    }
    return 0;
}
