C Program to show a kite is flying

Program:

#include<stdio.h>
#include<conio.h>
#include<graphics.h>
#include<stdlib.h>
void main()
{
int gm,gd=DETECT;
int i= 0,j=0,rnd_x=0,rnd_y,stop_me=0;
initgraph(&gd,&gm,"C:\\TURBOC3\\BGI");
srand(time());
while(stop_me<=1000)
{

if(i>=180 &&j>=100 ) // controlling kite, so that it wouldn't disappear from screen
{
rnd_x=rand()%4 -3;
rnd_y=rand()%5 -4;
}
else{
rnd_x=rand()%3;
rnd_y=rand()%3;
}
line(200+i,200-j,250+i,250-j);
line(200+i,200-j,150+i,250-j);
line(150+i,250-j,200+i,350-j);
line(200+i,350-j,250+i,250-j);
line(200+i,200-j,200+i,350-j);
arc(200+i,275-j,25,155,50);
line(0,500,200+i,225-j);
i=i+rnd_x;
j=j+rnd_y;
stop_me=5+stop_me;
delay(100);
clearviewport(); // clearing image which would make illusion of flying kite

}
getch();
closegraph();

}

Output:
