encode/decode program

[Vivi_BlckMage]

sup guys, i need help with a program that has to do the following(laugh all you want, I know its an easy program, but i cant seem to get the decode part to qork quite right):

Part a) Create a coder application that encodes or decodes a message using Unicode.

Part b) Modify Coder to produce the code by converting each letter in the original message to its corresponding Unicode number, add 2 to each number, and then convert these numbers back to characters to display a coded message. Keep all spaces between the words in their original places and realize that the letters 'y' and 'z' are to be converted to 'A' and 'B'.

any help will b appreciated.
