C++ Program for a Palindrome

Following is a C++ Program for a Palindrome

#include<iostream>
using namespace std; int main(){ char string1[20]; int i, length; int flag = 0; cout << "Enter a string: "; cin >> string1; length = strlen(string1); for(i=0;i < length ;i++){ if(string1[i] != string1[length-i-1]){ flag = 1; break; } } if (flag) { cout << string1 << " is not a palindrome" << endl; } else { cout << string1 << " is a palindrome" << endl; } system("pause"); return 0; }
