Please find attached two documents describing Challenge 7 that were briefly
described in our last meeting.

Let me know if you have any questions or require components.

Morse Code Ecoding Using Python Dictionary Definition:

MorseCode= {"A":".-", "B": "-...", "C": "-.-.", "D": "-..", "E": ".", "F": "..-.",
            "G": "--.", "H": "....","I": "..", "J": ".---", "K": "-.-", "L": ".-..",
            "M": "--", "N": "-.", "O": "---", "P": ".--.","Q":"--.-", "R":".-.",
            "S":"...", "T":"-", "U":"..-", "V":"...-", "W":".--", "X":"-..-",
            "Y": "-.--", "Z": "--..", "1": ".----", "2": "..---", "3": "...--",
            "4": "....-", "5": ".....","6":"-....","7": "--...", "8": "---..",
            "9": "----.", "0": "-----", ".": ".-.-.-", "’": ".----.", " ": " "};

Morse Code Ecoding Using a String Array For C or Python:

const char* MorseCode[] ={".-", "-...", "-.-.","-..", ".", "..-.",
                     "--.","....","..",".---","-.-",".-..","--","-.",
                     "---",".--.","--.-",".-.","...","-","..-","...-",
                     ".--","-..-","-.--","--..",".----","..---","...--",
                     "....-", ".....","-....","--...","---..","----.",
                     "-----"
                    };

const char *Ptext= "SOS";

............................................................................................

MorseCode[] is a constant array of Morse Code characters (dods & dashes) defined has strings.
MorseCode[0] is the string ".-", the Morse Code for A. The ASCII value of A is 65. Subtracting
65 from the ASCII value of A gives 0, the index of the first element of the array. The Morse codes 
for each of the charters of Ptext = "SOS" can be obtained by subtracting 65 from their ASCII value. 
However, if Ptext contains ASCII digits 0 to 9 their ASCII values must be translated to
produce an array index that follow the Z.
