The code below has the following problem.

-After backspace has been pressed (char code of 14): if 'key' is in the entry buffer, "Key has been typed " will be printed. This is what should happen.

-After return (enter) key has been pressed but before the backspace key has been pressed "Key has been typed " is NOT printed if 'key' is in the buffer. This should not happen. "Key has been typed " should be printed regardless, if 'key' is in the buffer.

Have I made a mistake in the code below?

But he makes the buffer empty, isn't that wrong behavior?

Above code now works. I discovered the problem:

The buffer was being cleared before the enter key was released, which meant that even though it was cleared, it was readded to the buffer straight away since the key was still down.
So, I've moved the buffer to being cleared after the enter key is released. Unfortunately, it is still added to the buffer because C++ is too fast for DB so I had to put dbwait(1) in aswell.
