Need this answer in C++ only PLease

My program works but not for numbers.

20.5 C++: Checking for Palindrome

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 #include using namespace std;

int main() {

string input; bool checkInput, isPalindrome;

isPalindrome = true;

do { checkInput = false;

cout << "Type a word to check for Palindrome: " << 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; } } if (isPalindrome) { cout << input <<" is a palindrome." << endl; } else { cout << input << " is not a palindrome." << endl; }

return 0; }

Input	Madam
Your output	Type a word to check for Palindrome: Madam is a palindrome.

Program timed out

Input	444244
Your output	Your program produced no output
Expected output	Type a word to check for Palindrome: 444244 is not a palindrome.

Compare output
