  You misunderstood the getch() function. If a character is waiting in the
keyboard queue, it will return it. If it isn't, then it will wait until you
press a key.
  The way to accomplish what you want is to use kbhit():

  while ( !kbhit() || (getch() != 'q') )
     printf("Neverending textstring");
