A palindrome is a phrase that reads the same both forward and backward. Write a C++ program that reads a line from cin, prints its characters in reverse order on cout, and then pronounces judgement on whether the input line is a palindrome. Use the substr function within a loop to extract and print the characters one by one from the string, starting at the end of the string; at the same time, extract corresponding character starting at the beginning of the sting to compare with it. For example, here are two sample runs of the program: Enter string: able was I ere I saw elba
able was I ere I saw elba
is a palindrome.
Enter string: madam I'm adam
madam I'm adam
is not a palindrome.
