Write a C++ program to encrypt and decrypt any given plain text using the Affine cipher

The student's programming assignment.

Write a C++ program to encrypt and decrypt any given plain text comprising of capital letters (A to Z) and spaces using the Affine cipher. For encryption, the program should prompt the user to input the "plain text" and "encryption key", and then display the "cipher text". Similarly, for decryption, the program should prompt the user to input the "cipher text" and the "decryption key", and output the "plain text". A good user interface is expected. Please write comments as much as possible to understand the program. Also, write the answer from your keyboard so I can copy it. Please don't put any image answers.
