Re: anti-standard code can compile -- about template class

Thanks Norbert,

I want to confirm that which code you have tried. In the original reply I
posted a small code segment, and according to others' suggestion, I have
enriched the code below.

I can compile the original code, but can not compile the following code. The
compile errors are listed below.

Which code are you compiling? Below one or original one?

Compile error messages are,

--------------------

--------------------

[Code]
#include <iostream>

using namespace std;

template <typename T> struct Base {
public:
    Base (int _i): i (_i)
    {

    }

    int i;
};

template <typename T> struct Derived : public Base<T> {
public:
    Derived (int _i) : Base<T> (_i)
    {
    }
    int get_i() { return i; }
};

int main()
{
    Derived<int> d (200);
    cout << d.get_i() << endl; // output 200
    return 0;
}
