The code looks pretty straightforward.=C2=A0 There are three reasons why it=
might not be quitting for you.
1) Most likely: you're never getting the SDL_QUIT event.2) SDL_DestroyRende=
rer is never returning for some reason.
3) SDL_DestroyWindow is never returning for some reason.
Probably #1 though.=C2=A0 Have you tried running it under a debugger to che=
ck on what's happening?

am I doing wrong here? This is lifted code. When the program runs it produc=
