I had quite a bit of confusion with Copy Constructors and Constructors
when I got back into C++ programming a few months ago (it had been
two years).  Here is what I did.  I seriously recommend you do this, not
only will it answer your question, but it will help you visualize
exactly
what is going on: (not tested, but should work)

class CLOWN
{
public:
	CLOWN(char *name) 
	{ 
		cout << "Constructor Called:" << name << endl; 
		myname = new char[strlen(name)+1];
		strcpy(myname,name);
	}

	CLOWN(CLOWN &bobo)
	{
		// Hi bobo
		cout << "Copy Constructor: " << myname << endl;

	}
	
	~CLOWN()
	{
		cout << "Destructor called: " << myname << endl;
	}
private:
	char *myname;
}

(int)float((int)(char *)) main()
{
	CLOWN bozo("bozo");
	bozo = new CLOWN("anak");
	CLOWN bongo("bongo");
	bozo = bongo;
	CLOWN *bingo = new CLOWN("bingo");
	delete bingo;
	// etc. 
};
