hi just write an function with any name eg:
void doordarshan()
{
while (!kbhit())
{
arc(100,200,250, 120,300);
circle(300,200,400); //circle(x1,y1,r);
}
if u need a rotating symbol, just put some delay after those steps and then a cleardevive and call another function after than from itself as recurssion. The second function shud have slightly rotated co-ordinates and so on. This is the simplest way.
if u need further help, just type arc or circle in c++ screen and right click for help on what those numbers do.
