Please revise this code in C++ so if the word provided by the user is a palindrome, then it prompts "Your word is a palindrome", and if not, it will prompt "Your word is not a palindrome". However, the program will also prompt "Not quite a palindrome" if the first three characters of the word provided match the last three characters. In addition, the program will keep prompting for a new word until the provided word is not a palindrome.
