hello want create new class variable pointer , initialize copy constructor. though know how copy constructor works refernce, cannot figure out how it. can me? example have definition: class a{ public: int a; private: }; and in code segment following: a *object= new a; a->a=10; *newobject= new a(*object); but segmentation fault. can me? tried: *newobject= new a(&(*object)); but doesn't work either. with kind of simple example, following uses default bit wise copy constructor works fine. the simple class looks like class bclass { public: int ivalue; }; and code use copy constructor looks like: bclass *pobject = new bclass; pobject->ivalue = 10; bclass *pobject2 = new bclass (*pobject); using microsoft visual studio 2005, above works fine. see implementing copy constructor . see copy constructor pointers objects .
