C++ Program to implement Operator Overloading (>>, <<)

Write a class which contains a string as private data member. Add a member function IsPalindrome that returns TRUE/FALSE depending upon whether the str is palindrome or not. Overload the <> operator to insert the string and print the string respectively along with appropriate message.
