Question

Let’s say I have ClientList class and I have declared like this.

class ChatMgr
{
   private:
   ClientList _userlist;
   ClientList *_userlist;
}

Then what is the difference? I know that the second one is the address of the instance and I need to initialize it using new to use it. Then for the first one, can I just access to the all the data members inside of the class without initializing it?

Thanks in advance….

You are correct, _userList is an actual instance of the ClientList class, so is initialised when ChatMgr is (its constructor is called), but *_userlist is a pointer, which is left uninitialised.
