C++ Palindrome String Program

In this C++ tutorial, you will learn how to write a C++ Program to check if the given string is a Palindrome string or not.

C++ Palindrome String

A string is a Palindrome, if this string value and its reversed value are same.

Program

In the following program, we read a string into str, and check if this string str is Palindrome or not.

main.cpp

#include <iostream>
using namespace std;

int main() {
    string str, reversed;
    cout << "Enter a string : ";
    cin >> str;
    
    //make a copy of given string to reversed
    reversed = str;
    //and reverse the string
    reverse(reversed.begin(), reversed.end());
    
    //check if str equals reversed
    if (str == reversed) {
        cout << "The string is a Palindrome." << endl;
    } else {
        cout << "The string is not a Palindrome." << endl;
    }
}

Output

Enter a string : moosoom
The string is a Palindrome.
Program ended with exit code: 0

Enter a string : apple
The string is not a Palindrome.
Program ended with exit code: 0
