Question

A palindrome is a word or a phrase that is the same when read both forward and backward. Examples are: "bob," "sees," or "never odd or even" (ignoring spaces). Write a program whose input is a word or phrase, and that outputs whether the input is a palindrome.

Ex: If the input is:

bob

the output is:

bob is a palindrome

Ex: If the input is:

bobby

the output is:

bobby is not a palindrome

IN C++ PLEASE!

Answer 1

#include <iostream>
#include <string>
#include <cctype>

using namespace std;

int main() {
    string data, reversed, modified;
    char ch;
    getline(cin, data);
    for (int i = 0; i < data.size(); ++i) {
        ch = tolower(data[i]);
        if (isalnum(ch)) {
            modified += ch;
            reversed = ch + reversed;
        }
    }
    if (reversed == modified)
        cout << data << " is a palindrome" << endl;
    else
        cout << data << " is not a palindrome" << endl;
    return 0;
}
