Answer 3

All letters have their numerical codes. I don't know what programming language you are using, so I will be as general as possible.

Let's assume A has code 45
(it is not, but we are about method, not realization). Then B will be 46 and so on. We have 26 letters.

Initiation:
CurrentCode = 45;

Event on keyboard key pressed:
PrintLetterByCode( CurrentCode );
CurrentCode + 1;
IF ( CurrentCode == 45+26 )
THEN CurrentCode = 45;

Adopt to your kanguage and bind event on keypress. Loop without looping. Only condition.
