A simple program that I wrote a long time ago that will check if the give number is odd or even using structure in C++.

Program Listing

#include <iostream>

#include <iomanip>

using namespace std;

struct odd {

int n;

  int odd_even() {

  if (n % 2 == 0)

        {

                 cout << n <<" Number is even!\n";

        }

        else

        {

                 cout << n << " Number is odd!\n";

        }

   return(n);

  }

};

main() {

    odd value;

   cout << "\t\t ODD and Even Number Determiner";

   cout << "\n\n";

   cout << "Enter a Number :";

   cin >> value.n;

   cout << "\n\n";

   cout << value.odd_even();

   cout << "\n\n";

   system("pause");
