Morse code is a sequence of dashes and dots that can be used to represent a mess

Question

Morse code is a sequence of dashes and dots that can be used to represent a message in English.

Each letter in a particular alphabet is represented by a unique pattern of dashes and dots in

Morse code. You can find more details about the Morse code on Wikipedia.

In this project, your job is to create a code that can convert an English string into Morse code.

Then you can either beep the message or flash it (using any graphics library).

Your code should also be able to convert Morse code into English text. (You may not be able

to do it directly. Look up Quinary Form of Morse Code.)

A few things to keep in mind are:

1. Graphics (nothing fancy) can be added to flash the Morse code.

2. File handling (i.e. saving the Morse code in a text file)

NOTE: The code should be in " C Language/ C+"

Explanation / Answer

function [output] = english2morse(text)
    definitions = {' .-' ' -...' ' -.-.' ' -..' ' .' ' ..-.' ' --.' ' ....' ' ..' ' .---' ' -.-' ' .-..' ' --' ' -.' ' ---' ' .--.' ' --.-' ' .-.' ' ...' ' -' ' ..-' ' ..-' ' .--' ' -..-' ' -.--' ' --..' ' ' '-----' '.----' '..---' '...--' '....-' '.....' '-....' '--...' '---..' '----.' '.-.-.-' '--..--' '..--..' '..--.' '---...' '.-..-.' '.----.' '-...-'};

output = definitions(text);
end
