I have written the following source
#include <iostream>
using namespace std;
template <class T>
class AAA
{
public:
void f() { cout << T() << " "; }
};
int main ( void )
{
AAA<int*> a;
AAA<int> b;
a.f(); /// in this case, T() == NULL??
b.f();
return 0;
}
and console print is 00000000 0. ( in visual studio 2010 )
if T is int*, T() == NULL? and is it always true?
