check elements on string to see if palindrome

#include <iostream>
using namespace std;
int main ()

        string word;
        int wordsize;

        // use getline, not cin >> because using strings 
        cout << "Please enter a word." << endl;
        getline (cin, word);

        wordsize = word.length();

        cout << "The length of the word is " << wordsize << "." << endl;

        
        for (int i=0; i < wordsize/2 ; i++)
        {


                // if statement for word if equal, break loop and return YES
                if (word[i]==word[wordsize-i-1])
                {
                        cout << "Checking element " << i << " with element " << wordsize - i -1 << "." << endl;
