Answer 1

in order to solve it (one possible way), you must make 'ptr' actually to point to a adress where a myClass objects exists. In order to exist, you have to create it, e.g.

class sampleClass
{
public:
   sampleClass()
   {
       ptr = new myClass();
   }
private:
   myClass* ptr;
};

you might still consider using C++11's unique_ptr or shared_ptr instead of a raw pointer, though.
