Ok I was able to validate user input if the user would enter a larger number or a negative number but how do you validate if the user happens to enter a letter or word, even character i.e % # @, or if the user enters all. How do you block the user to only enter a number for example 1 to 6?
Also, What about if the user presses space? Please show examples.
Is there an easier way as to using ASCII character set in maybe a switch case.
