Write your reply.

assistant: Whatever tool is issuing the warning is doing an excellent job of
 helping you.  But the message kind of stinks.  I would prefer
 something more along the lines of "soon to be out of scope address
 being returned".  But a misleading warning is still better than no
 warning at all!
 What is the "lifspan" of 'i'.  It's contents are only valid while
 'i' exists.  It no longer exists then the function returns.  So if
 anyone tries to dereference the returned pointer, he may get back
 the right answer, the wrong answer, or the system may even crash
 and burn.
 That's the beauty of "undefined behavior".  You can very well get
 "correct" results on some platforms.  But even on your platform, I
 *know* I can make it fail.  What's happening is that the address
 returned is (or rather was) on the stack.  You had no intervening
 uses of the stack between the function call and the dereferening
 of the returned pointer.  If you add some code which "clobbers the
 stack", you won't be getting the right answer.
 YES!  The lifetime of the variable needs to match the lifetime of the
 pointer to the variable.  Perhaps making i 'static' would be
 appropriate.

Write your reply.

assistant: I'd say you can't do it.
You can't return an incomplete type, Jerry.
Nope.  Expanding your code out to match Christian's code:
class B;
class A {
public:
    A(int) {}
    B func1() { return B(1); }
};
class B {
public:
    B(int) {}
    A func2(int a) { return A(1); }
};
This compiles as:
[0] e:\tmp\s>gcc -c t.cc
t.cc: In method `class B A::func1()':
t.cc:6: return-type `B' is an incomplete type
t.cc:6: type `B' is not yet defined
However, I'd propose that if you could get around this (I don't think you
can), you'd be given another (minor) roadblock: you don't know that B::B(int)
exists at that point.  You'd have to move A::func1() to below class B's
declaration.  In fact, this was what I originally expected, but obviously we
both missed the more important point.
You have to resort to making either A::func1() or B::func2() return a pointer
or reference (probably the former).  Which means allocating memory on the
heap.

The STL classes are generally within 2-5% of the speed of hand-coded C/C++
(non-templated) libraries.  Further, you can (and trust me, I have!)
generally switch between linked lists, vectors, and double-ended queues with
very little code changes, so you can see which is the faster option.  No
coding needed.

assistant: Hola Kurt!
   I think you are a little lazy �aren't you? The program is very easy.
try something like this (I haven't tested it and I have written it in here as
I'm thinking on it)
template<class tipo>
int sign(tipo x)
    {
    if (x>0) return(1);
    if (x<0) return(-1);
    if (x=0) return(0);
    }
Using a Template you can use any type for the number to compare  Ej:
    char a;
    int  b;
    float c;
    sign(a);
    sign(b);
    sign(c);
  You can call the function with any type of parameter.
   Not at all.  ;)

iterator to store the current state of an iteration.
Yes.  It's  useful in cases where the values of an object's attributes
are modified but not the object's state as perceived by its clients.
An  example is objects performing lazy evaluation. Toward its clients,
an object changes its state when the state of another object  changes
of  which its state depends. The object's implementation may defer the
state update to the moment when the state is retrieved by a client.
Borland C++ supports it.

Where did you read it's no longer permitted?
Yes, mallos is definitely a C-ism, but it still works. While new/delete tend
to have bugs in nearly every compiler. And sometimes in the OS. (I had a
rare, but reproductable bug that manifested in windows using new/del and not
with malloc/free.
So when I need unformatted memory storage, I better use malloc, not new
char[]. (Okay, I don't do that, I have a simple memblk class that does it as
internal work.)
But using a modern C++ compiler malloc will definitely be a problem, as new
will very probably set up with sophisticated new handlet or exception-
throwing. So on such a compiler I'll probably switch back to new[] in that
class.
