using only #include and #include Write a program in C that will read an input from the user and print it back to the user if it is a palindrome. The string ends when it encounters a whitespace. The input string is at most 30 characters. Assume the string has no spaces and distinguish between and lowercase. So madam is a palindrome, but MadAm is not a palindrome. Use scanf and %s to read the string. Sample Test: Enter a string: madam madam is a palindrome. Enter a string: 09023 09023 is not a palindrome.
