This program shift all your text to the right by three(3) to form the chipher text.(encryption) while to convert (decrypt) the chipher text back to the readable text, it shift to the left by three(3).

To be able to achived this you will use the
* encrypt() function for encryption 
 decrypt() function  for  decryption

 Use this your object name to access the encrypt and decrypt funtion.
 
 Code sample:
 
   objName.encrypt("hello cryptography") // output khoor#fu|swrjudsk|
   
   Now to decrypt:
   
   objName.decrypt("khoor#fu|swrjudsk|"); //output hello cryptography
   


END.
