Could someone explain some code?

But, unless I have completely lost track, we were not discussing a
header (I have never come across a header with main() in it.

You have completely lost track, then. See the post that started the
thread. The two lines quoted _were_ in a header. And I don't see any
'main' in it either.

Nope. Here's the original code under discussion:

-----------

#ifndef _COUNTER_H
#define _COUNTER_H
#include <iostream>
using namespace std;

class Counter
{
public:
int count;
public:
* Counter(){count = 0;}
void operator ++() { ++count; }
int GetCount() { return count; }
void SetCount( int c ) { count = c; }
void PrintCount() { cout << "\n The count is " << count; }

};

class NewCounterublic Counter
{
public:
* void operator --() { --count; }
};

#endif

Much better is to actually understand what using declarations and
using directives do.

Indeed. Feel up to posting a tutorial? I didn't. The people in question
should find a good book that explains the subject. Now, if we only knew
of some web site or something that reviewed books

Lose the leading underscore on that macro name.


This is a very bad idea. Try to avoid ever putting 'using' directives
in a header.


This one declares and defines the default constructor for this class.

I thought the * was actually part of the code, and I could not figure out what
it was supposed to do
