Cipher: Decrypt and Encrypt, C/C++ Programming

Assignment Help:
You must write a program that can both decrypt and encrypt a single word that is entered by the

user. The initial choice of encryption and decryption is left up to the user. Additionally, the user will enter a value to be utilized when determining how to translate the character.

Decryption: Convert all characters in the word by utilizing the discovered map index

Having trouble with the decryption portion:

¦ Given a character in the word, determine its index in the map string

¦ Add the position to the first character in range of valid characters for a word

? This is the position of the character in the alphabet!

? What is the range of valid characters? Check the validation step. What is the first character in that range?
