The**PString** class should add a member function which determines whether thestring is a palindrome.#### Project 2Write a class named **EncryptableString** that is derived from the **STL** stringclass. The **EncryptableString** class adds a member function which encrypts thestring contained in the object by replacing each letter with its successor inthe ASCII ordering.

Assume that the only characters to be encrypted in an **EncryptableString**object are letters (a z and A Z), and numbers (0 9), and that thesuccessor of z is a, the successor of Z is A, and the successor of 9is 0. Other characters should not be encrypted, such as spaces andpunctuation.### Lab#### Project 1Complete the People At MCC classes#### Project 2Write classes representing animals, birds, and dogs
