How to resolve the algorithm Keyboard input/Obtain a Y or N response step by step in the FreeBASIC programming language

Table of Contents

Problem Statement

Obtain a valid   Y   or   N   response from the keyboard. The keyboard should be flushed, so that any outstanding key-presses are removed, preventing any existing   Y   or   N   key-press from being evaluated. The response should be obtained as soon as   Y   or   N   are pressed, and there should be no need to press an   enter   key.

Let's start with the solution:

While InKey <> "" : Wend '' flush keyboard buffer
Print "Do you want to continue y/n : ";
Dim answer As String

Do
  answer = LCase(Inkey)
Loop Until answer = "y" OrElse answer = "n"

Print answer '' echo response to console
