A simple C++ program using class

Note: Use new compiler (Code blocks or Dev C++)  to run these C++ programs. Old  Turbo C compiler does not supports some new features of C++.

If you want to run these programs on old Turbo C++ compiler use  <iostream.h> instead of <iostream> , do not use ( using namespace std; ) , use { getch(); } to hold run-time screen , use void main() instead of int main() .

C++ program to check a number weather palindrome or not. 

#include<iostream>

using namespace std;

class palindrome

{

   private:

   int num;

   public:

   void get(int u)

   {

     num = u;

   }

  

    void disp()

   { 

      int temp, rem, rev;

      temp = num;

    

       while(num>0)

       { 

         rem = num % 10;

         rev = rev*10 + num;

         num = num / 10;

        }

  

       if (rev == temp)

         cout << " Entered number is palindrome. \n";

    

       else

        cout << "Entered number is not palindrome. \n";

    }

};

int main()

{

  int a;

  

  palindrome x;

  cout  << "Enter a number. \n";

  cin >> a;

  x.get(a);

  x.disp();

  

  return 0;

}
