c++ check palindrome

#include<iostream>
#include<ctype.h>
using namespace std;
int main() {
	string s; cin >> s;
	int a = 0;
	for(int i = 0; i < (s.length() / 2); i++) 
		if(s[i] == s[s.length() - 1 - i]) a++;
	if(a == (s.length() / 2)) cout << "YES";
	else cout << "NO";
	return 0;
}

check if a string is palindrome cpp

// Check whether the string is a palindrome or not.
#include <bits/stdc++.h>

using namespace std;

int main(){
    string s;
    cin >> s;
    
    int l = 0;
    int h = s.length()-1;

    while(h > l){
        if(s[l++] != s[h--]){
            cout << "Not a palindrome" << endl;
            return 0;
        }
    }
    cout << "Is a palindrome" << endl;
    return 0;

palindrome program in c++

#include <iostream>


bool isPalindrome (int number) {
    int decomposed = number, reversed = 0;
    while (decomposed) {
        reversed = 10 * reversed + (decomposed % 10);
        decomposed /= 10;
    }
    return reversed == number;
}

palindrome checker in c++

		cout << "Palindrome!" << endl;
	}
	else
	{
		cout << "Not Palindrome!" << endl;
