#include <iostream>
using namespace std;
int main()
{
    int number_a;
    cout << "Enter an integer: ";
// Obtain input Number_a value
    cin >> number_a;
// input number divide by 2 for check reminder is 0 , true mean Even
    if ( number_a % 2 == 0)
        cout << number_a << " Number is Even."<<endl;
    else
// if Reminder not 0 then Odd number else execute 
        cout << number_a << " Number is odd."<<endl;
    return 0;
}

Output:
