I need help passing a string that the user entered in Main in to a constructor from the class Message.

In main(), you will need to create object of the Message class. You will use this object to call the functions in the Message class that will encrypt, decrypt, save, and print the words retrieved from the document.

Before you create this Message object, you should prompt the user to enter an encryption/decryption key. The same key must be used for decryption as was used for encryption. Otherwise, the algorithms will not produce the correct results. Once the user enters the key, pass this string in to the constructor of the Message class when creating your Message object. This key is ultimately converted to upper case and stored in the "key" data member in the Vigenere class.

//Main:

/* The purpose of this assignment is to encrypt outgoing messages and decrypt incoming messages using a Vigenere Cypher. This program encrypt outgoing messages and decrypt incoming messages using a Vigenere Cypher.*/

//Close file inFile.close();

}

"; cin.get(); }
