Palindrome in C++

This program tells weather the word is palindrome or not and reverses the word given by the user with a number of letters.

#include <iostream>

#include <cstring> ##To use string library

using namespace std;

int main() {

    string word;

        int i;

        int points=0;

        cout << "Enter the palindrome word(small letter) you want check: ";

        getline(cin, word); #Taking the input from the user

        int a = word.length(); ##Counting numbers of words and storing in integer a

        cout << "The word is " << a << " letters long." << endl;

        cout << "The reverse word is ";

        {              ##Use of reverse iterator to reverse the word

            for (std::string::reverse_iterator rit = word.rbegin(); rit != word.rend(); ++rit)

            

                cout << *rit;

        }

        cout << ". \n";

        for (i = 0; i <= a; i++){    ##Using for loop to compare word

            if(word[i]!=word[a-i-1]) {

                points = 1; ##if true

                break;

            }

        }

    if (points) { ##Incase of true

        cout << word << " is not a palindrome" << endl;

    }

    else { ##Incase of false

        cout << word << " is a palindrome" << endl;

    }

    system("pause");

    return 0;

}
