Turbo C environment, program overview:
-------------------------------
while (no key pressed) {
display string
sleep(5 minutes) / delay(5 minutes)
clear string
change screen coordinates
}
-------------------------------
Requirement: When no key is pressed, refresh the string every 5 minutes. And respond to key presses at any time (exit when a key is pressed).
Now the situation is that although there is a key pressed, it must wait until the 5 minutes are up before it can exit.
