Answer 1

Do you mean to randomly create string, that will match regexp?

Answer 2

Try to create key chunk by chunk then concatenate they with '-'

Answer 3

@Ahmad answering previous question. Chunk == part.

Answer 6

no ,, the max value is never reach in Random for that you have to add one for it if you want random to get it Xan

Ahmad Akil No you don't HAVE to. My code works. There's rarely only one way to do something. 'A' resolves to 48 anyway, and is better!
