Weekly Challenge #8 – A Trio of Ciphers

Not one, not two but three ciphers for you to program. For each cipher, write a program which asks the user to enter a plaintext message. Your program should then encrypt the message according to the rules shown in each task. Finally your program should output the encrypted version of the message.

One slight hurdle though – it’s up to you to work out what each cipher is doing!
