Was I being dogmatic?

My point is that &array seems to work okay with formatted output but may not work in other situations. &array in C++ is a different type than arrar and &array[0], and behaves differently. Yes, they all return the same address; but, remember, C is no longer a true subset of C++ since there are now too many gotchas.

#include <iostream>
#include <string>

using namespace std;

void print_myself(wchar_t* myself)
{
wcout << myself << endl;
}

int _tmain(int argc, _TCHAR* argv[])
{
wchar_t myself[] = L"George Jackson";

print_myself(myself);
print_myself(&myself[0]);

// wchar_t (*myself_ptr)[15] = &myself;
print_myself(&myself); // Won't compile in C++ as is.

return 0;
}

Thus, it should not even be an alternative to array and &array[0].

I certainly don't. I was just curious as to why you and George insisted on beating a dead horse.

3. I doubt whether it is useful to define a function pointer with empty parameter list -- too restricted.

I am sorry to make you mad, CPallini. Maybe my question is too hard?

1. I do not quite catch your points, why a class must implement a function without any parameters?

2. I want to confirm that, the declaration of variable pmf could be pointed to any member functions of class (type) T which returns type R and no input parameters?
