(object.*func_ptr)(10); So the value is used to determine which member function to call
- Kaijin
I''m not 100% sure about this because I don''t use them but I think member function pointers are a relative offset within a class. When you call them you always have to provide an object to call them on like so:

I ran the code in the debugger and it seems that the function pointer gets implicitly converted to a bool, which results in a '1' being written. To see what's going on, try changing the line to:
The output is:
// Website // Google // GameDev // NeHe // MSDN // OpenGL Extensions //

cout << boolalpha << "ca.count() = " << ca.count << endl; The output is:
ca.count() = true ~nz // Website // Google // GameDev // NeHe // MSDN // OpenGL Extensions //

No, actually you are wrong. It would be a member function pointer if he did
&a::count
His expression, a.count without parenthesis is completely illegal C++ code and should generate a compiler error. It''s the fault of his compiler.
Ah yes, of course. You are right.
nonpop, I tried compiling your code using gcc and it wouldn''t compile. I guess it must be a bug with the compiler.

Of course it''s the fault of the compiler, he''s using VC++ 6!
I did a quick test with the sample code w/ borland''s compiler and it complains about the syntax as well.

Nice, quite the thread here...
Thx for the answers, even though some of them were a bit off topic
