According to the C++ standard "static const" member variables can be declarend
_and_ defined immediately inside the declaration of the class. It should not be
neccessary to declare A::N outside the class again. Other compilers "microsoft
express 2005" by the way do accept this code. The definition of A::N is
present. Otherwise, why does this code compile and link fine?
This program is accepted by gcc:
#include <iostream>
#include <algorithm>
struct A {
static const int N = 2;
};
int main ()
{
std::cout << "Number: " << A::N << "\n";
}
This program is _not_ accepted by gcc:
#include <iostream>
#include <algorithm>
struct A {
static const int N = 2;
};
int main ()
{
std::cout << "Number: " << std::min(1, A::N) << "\n";
}
Static const member variables may be defined and declared the way I have
proposed. According to the standard it is no more neccessary to provide a
declaration outside the class, I know that this was once neccessary. The web is
full of examples that shows that my declaration and definition of A::N is legal
in C++. Sorry, for insisting to look at this problem once again.
