Write a C++ program to check whether a given string is a palindrome or not.
Example:
|
1 2 3 4 5 |
Input: mom Output: Palindrome Input: Malayalam Output: Palindrome |
Palindrome String: A palindrome string is that string which in reverse is equal to the original string.
Basically, in the program, we need to implement the following steps:
- Taking string input from the user.
- Calculating the size of the string.
- Reverse the string.
- If the reverse of the string is not equal to the original string, then the string is not palindrome or else it id palindrome.
So let’s do the same in C++.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
#include <iostream> using namespace std; int main() { string str; cout<<"Enter a string: "; cin >> str; string rev=""; for(int i=str.length()-1; i>=0; i--){ rev +=str[i]; } if(rev == str) cout << "Palindrome"; else cout << "Not Palindrome"; return 0; } |
