Question

A palindrome number is a number that remains the same when its digits are reversed. Like 16461, for example, is a palindrome number .Write a Program to generate the Palindrome numbers between 1 and 200 in an output file named "palindrome.txt" .

Answer 1

Answer:

Code is given below and output is attached as an image.

Explanation:

#include <iostream>

#include <fstream>

using namespace std;

bool isPalindrome(int n)

{

       // Find reverse of n

       int rev = 0;

       for (int i = n; i > 0; i /= 10)

               rev = rev * 10 + i % 10;

       // If n and rev are same,then n is a palindrome

       return (n == rev);

}

int main()

{

       int min = 1;        // Lower Bound

       int max = 200;      // Upper Bound

       ofstream myfile;

       myfile.open("palindrome.txt");

       for (int i = min + 1; i < max; i++)

               if (isPalindrome(i))

                       myfile << i << endl;

       myfile.close();

       return 0;

}
