// Substitution Cipher /* The substitution cipher is a simple and very old method of sending secret messages. You might have used this cipher with your friends when you were a kid. Basically, each letter of the alphabet gets replaced by another letter of the alphabet. For example, every 'a' gets replaced with an 'X', and every 'b' gets replaced with a 'Z', etc. Write a program that asks a user to Enter a secret message. Encrypt this message using the substitution cipher (below) and display the encrypted message. Then decrypt the encrypted message back to the original message (text). For example, to encrypt, you can replace the character at position n in the alphabet with the character at position n in the key. To decrypt, you can replace the character at position n in key with the character position n in the alphabet. Have fun! Remember, the less code you write, the less code you have to test! Reuse existing functionality in libraries in the std::string class! */ Utilize the below two strings in your solution string alphabet {"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"}; string key {"XZNLWEBGJHQDYVTKFUOMPCIASRxznlwebgjhqdyvtkfuompciasr"};
