In this homework assignment, you are going to write 2 programs to encode and decode messages using codes such as Morse code. NOTE : You will be writing two programs. Both programs will use the class Code. One program will use the class to encode a message. The second will use the code to decode the message. The Morse code table is given below :

Our software will support codes that consist of symbols followed by a blank space. For example, in a message if an A appears, it will be replace by ".- ". The trailing space indicates the end of the codeword for that character. (NOTE: We will only be using the characters A-Z. Morse code words are separated by a space, so the message "cat" would be -.-. .- - x where x indicates the end of message. Note that spaces between words are denoted by 7 dots ".......". You can assume that encoded messages end with a lowercase x (which means STOP). When converting a message from text to code, a period "." should be converted to an x.)

Requirements

Your program should include the following class :

class Code { public: Code(); // Default constructor - loads and uses morse code Code(vector codewords); // constructor loading customized code string encode(vector message); // encodes a message consisting of A-Z string decode(vector message); // decodes a message private: vector codewords; // this is a codeword vector parallel to A-Z vector alpha; // this is the vector A-Z vector alphacode(); // function builds the vector alpha - A B C etc. vector morsecode(); // function the vector codewords containing morse code string encode(char x); //returns the codeword for the character x char decode(string c); //returns the character for the codeword c. }; 

You will need to submit your programs that test both encode and decode.. The first (encode) will input an alphabetic message from a file, and use the class to build the morse code string, and then output the string. The second (decode) will input a morse code string from a file and use the classto build the decoded string, and then output the string. You can download the functions morsecodeand alphacode.
