    signed long num1 = 0;
    cout << "\n\n Check whether a number is positive, negative or zero :\n";
    cout << "-----------------------------------------------------------\n";
    cout << " Enter a number : ";
    cin >> num1;
    if(num1 > 0)
    {
        cout << " The entered number is positive.\n\n";
    }
    else if(num1 < 0)
    {
        cout << " The entered number is negative.\n\n";
