13.8 Caesar Cipher v2 (Decryption) Description A Caesar cipher is one of the first and most simple encryption methods. It works by shifting al letters in the original message (plaintext) by certain fixed amount (the amounts represents the encryption key). The resulting encoded text is called ciphertext. Example Key (Shift): 3 Plaintext: ABC Ciphertext: DEF Your goal is to implement a Caesar cipher program that receives a single encrypted letter (character) and decrypt it. NOTE: This time you are receiving a character (char) and must output a character as well. Additionally, only lowercase letters (a-z) will be used Requirements Treat the plaintext and ciphertext as char variables Read input from keyboard using the scant function expecting inputs in the following format %d %c" the first element being the key and the second one the ciphertext) Output only the result strictly using the following format "%c' (the plaintext) Note: You cannot use any control statement even if you know it!
