c++ - calling the default constructor

Question

class base {
    int i;
public:
    base()
    {
        i = 10;
        cout << "in the constructor" << endl;
    }
};

int main()
{
    base a;// here is the point of doubt
    getch();
}

What is the difference between base a and base a()?

in the first case the constructor gets called but not in the second case!

Answer 1

The second one is declaring a function a() that returns a base object. :-)
