static int: One variable per application Can be accessed without object.
Public static final int MAX = 10000; // Defined in MyClass // Somewhere else you could do int max be accessed per instance).

What is the right way of initializing a static map? Do we need a static function that will initialize it?

If you appreciate what static typing gives you, you'll learn how the type system of the programming language you with two elements.
I'd take Yegge's (and Ola Bini's) opinions on static typing with a grain of salt.

I've heard that, in C++, the static_cast function should be preferred to C-style or simple function-style casting. Is this true? Why?

Standard conversions between fundamental types:

Hello.
I have a simple question. Is there a way ( using reflections I suppose ) to iterate all the static values of a class?
For instance
class Any { static int one = 1; static int two = 2; static int three = 3; public static void main( String [] args...

readParamString(Object params, int index)
and they have in that class 10 fields
final static int PARAM1 = 1 ... final static int PARAM10 = 10
which are being used with readParam...

No checks on the validity.
It might be a static(int) foo compares most to c++ reinterpret_cast<int> , i.e.
The difference is that (int)foo can mean half a dozen different things.
Of the cast.

Try to see which cast is faster (not necessary better): new c++ case or old fashion C style cast. Any ideas?

Be no difference at all if you compare int() to equivalent functionality of static_cast<int>() .

Struct A { static const int a = 5; struct B { static const int b = a; }; }; int main() { return A::B::b; }
The above code compiles. However if you go by Effective C++ book by Scott Myers(pg 14); We need a definition for a in addition to the declaration...
