Simple Question: Is a class's destructor called when a pointer to an objected is delete'd?

// MC.h

class MC
{
public:
  MC();
  ~MC();

  int foo();

  static int m_mcCount;
}
int MC::m_mcCount = 0;

// MC.cpp

MC::MC()
{
 m_mcCount++;
}

MC::~MC()
{
 m_mcCount--;
}

int MC::foo()
{
 return 0;
}

// main.cpp

int main()
{
  MC *myMC;
  myMC = new MC;
  MC->foo();
  delete MC;
return 0;
}
In the above example, the member m_mcCount is set to 1 when myMC allocates a new MC object (correct?). Is m_mcCount reduced to 0 when myMC is delete'd? ================== My (soon-to-be) Cherished Cookie of Appreciation: -- MattB - WinSock advice -- -- Sneftel - how 'extern' works -- -- LessBread - Hooks ans Shared Memory -- -- groby - safe assumed MTU size -- [edited by - zackriggle on December 13, 2003 1:31:10 AM]

Well, you could do some experimentation, by placing a printf in the destructor to see if it''s called, but I''ll give the short answer: Yes, if the object was allocated with a new call, then deleting it will call the destructor too.

I like pie.
