Answer 1

AGW GAMING do you know why it doesn't work on code playground?
because code playground doesn't support those MS-DOS headers(graphics.h conio.h and dos.h are the part of MS-DOS non-standard library) which is too old to use it today.

Answer 2

let's assume that you're using it for legacy or out of curiosity
you're trying to output "RAJ" in different colors and positions very rapidly(which is impossible to see with our eyes) and then you're delaying it, iterating it 450 times!
what you should do is after updating the output's position and color, set the delay function below that, for every change so you could see it.

here's the example(I don't use MS-DOS, I modified it just by looking at the function name)

for(int i = 1; i < 450; i++){
cleardevice();
settextstyle(1,0,5);
move to(250+i,200);
setcolour(BLUE);
outtext("RAJ");
delay(10);

move to(250,200+i);
setcolour(YELLOW);
outtext("RAJ");
delay(10);

move to(250-i,200);
setcolour(WHITE);
outtext("RAJ");
delay(10);

move to(250,200-i);
setcolour(PINK);
outtext("RAJ");
delay(10);

move to(250,200);
setcolour(RED);
outtext("RAJ");
delay(10);
}
