// Runs an infinite loop that listens to the keyboard input.
|
|
// When a key is pressed (any key), the program blackens the screen,
|
|
// i.e. writes "black" in every pixel;
|
|
// the screen should remain fully black as long as the key is pressed.
|
|
// When no key is pressed, the program clears the screen, i.e. writes
|
|
// "white" in every pixel;
|
|
// the screen should remain fully clear as long as no key is pressed.
