There are two problems with my C++ code. This is about fromMorse to English text and English text to Morse code.

a) There are some warnings.

b) The validation when I convert from Morse Code to Englishtext, I have to input the Morse Code only.

Here is my code: Help me to fix it to function properly.Thanks!
