Question

class TConst
{
    const int i;
    int& ref;
    public:
    TConst(int n):i(n),ref(n){}
    static void p1(){prn(i);}//error here
};

My compiler generates an error when I try to use a const class member in a static member-function.

Why is it not allowed?

Answer 1

The const member is initialized during the object construction. The static members are not dependent on the object creation and don’t have access to this pointer hence they don’t know where your const member variable resides.
