    int y = 9;
    cout<<(refFunction(x, y));
    return 0;
}


//Function definition
int& refFunction(int& num1, int& num2)
{
    //If num 1 is odd and 2 even
    if(num1%2 != 0 && num2%2 == 0)
    {
        return num1;
    }
    //If num1 is even and num2 is odd
    else if(num1%2 == 0 && num2%2 != 0)
    {
        return num2;
    }
    //If both are odd
    else
    {
        //Return the small one
        return (num1 < num2) ? num1 : num2;
    }
}
