In C++ language Magic Decoder Ring. A one-time pad is a coding device that uses each character of a key string only once to encode and decode a corresponding character in a message string. Thus, the first character in the key is used to encode and decode the first character in the clear message, the second character in the key is used with the second character in the message, etc. No portion of the key is reused in subsequent messages, making for a very solid coding system, assuming a randomly generated key. You will need to create a class titled MagicDecoderRing that contains the variables and functions needed for obtaining the clear and key texts, encoding and decoding the messages, writing out the encoded message etc. You will need to instantiate an instance of this class in your main function to run your program and encode and decode messages. You need to further break your MagicDecoderRing code down into many small functions that each can be described with a single sentence…
