Write a function isPalindrome() that checks if a word is a Palindrome or not. Allow the user to type a string to test for Palindrome. Test your program on the following strings: "Madam", "abba", "22", "67876", "444244", and "Racecar"
Make sure that when determining whether a string is a palindrome, cases are ignored, that is, uppercase and lowercase letters are considered the same.
#include <iostream>
#include <string>
using namespace std;
int main()
{
  string input;
  bool checkInput, isPalindrome;
  isPalindrome = true;
  do
  {
     checkInput = false;
     cout << "Type a word to check for Palindrome: n" << endl;
     getline(cin, input);
     for (unsigned int i = 0; i < input.size(); i++)
     {
        if (input[i] < 65 || input[i] > 90 && input[i] < 97 || input[i] > 122)
        {
           checkInput = true;
        }
     }
  } while (checkInput);
  for (unsigned int i = 0, j = input.size() - 1; i < input.size(); i++, j--)
  {
     if (input[i] != input[j] && input[i] + 32 != input[j] && input[i] - 32 != input[j])
     {
           isPalindrome = false;
          Â
     }
  }
  if (isPalindrome)
  {
     cout << input <<" is a palindrome." << endl;
  }
  else
  {
     cout << input << " is not a palindrome." << endl;
  }
  return 0;
}
