C++ Class Static variable problem - C programmer new to C++
- by Microkernel
Hi guys,
I am a C programmer, but had learnt C++ @school longtime back. Now I am trying to write code in C++ but getting compiler error. Please check and tell me whats wrong with my code.
typedef class _filter_session
{
private:
static int session_count; /* Number of sessions count -- Static */
public:
_filter_session(); /* Constructor */
~_filter_session(); /* Destructor */
}FILTER_SESSION;
_filter_session::_filter_session(void)
{
(this->session_count)++;
return;
}
_filter_session::~_filter_session(void)
{
(this->session_count)--;
return;
}
The error that I am getting is
"error LNK2001: unresolved external symbol "private: static int _filter_session::session_count" (?session_count@_filter_session@@0HA)"
I am using Visual Studio 2005 by the way.
Plz plz help me.
Regards,
Microkernel
