I need to make a c++ program that involves herritance:

-Create a Cipher class that contains:

protected:

string alphabet;

public:

parameter constructor

setter for alphabet

getter for alphabet

encrypt(message)=0 function

decrypt(ciphertext)=0 function

-Create CaesarCipher class with Cipher heritance:

private:

variable shift int type

public:

parameter constructor

Setter for shift

getter for shift

encrypt(message) function definition

decrypt(ciphertext) function definition

-Create AtbashCipher with Cipher heritance:

encrypt(message) function definition

decrypt(ciphertext) function definition

-Create Message class:

private:

variable message and encryptionMethod type string

Variable caeser type CeasarCipher

Variable atbash type AtbashCipher

public:

Parameter constructor

message setters

message getters

sendMessage()

sendMessage(int)

recieveMessage(ciphertext, int)
