**Please it is necessary to use the functions and the names given. It is also important to use string and getline.**

Implement two decryption functions corresponding to the above ciphers. When decrypting ciphertext, ensure that the produced decrypted string is equal to the original plaintext:

decryptCaesar(ciphertext, rshift) == plaintext
decryptVigenere(ciphertext, keyword) == plaintext
Write a program decryption. cpp that uses the above functions to demonstrate encryption and decryption for both ciphers.

It should first ask the user to input plaintext, then ask for a right shift for the Caesar cipher and report the ciphertext and its subsequent decryption. After that, it should do the same for the Vigenere cipher.

Example:

$ ./decryption

Enter plaintext: Hello, World!

= Caesar =
Enter shift : 10
Ciphertext : Rovvy, Gybvn!
Decrypted : Hello, World!

= Vigenere =
Enter keyword : cake
Ciphertext : Jevpq, Wyvnd!
Decrypted : Hello, World!

(When reporting decrypted strings, they should be the result of applying decryption functions to the ciphertext, not the original plaintext variable.)
