Constructors CAN be declared in protected section of the class.class A {public: static A* Create(int x) { return new A(x); }protected: A(int x) { b = x; }private: int b;};A *a = A::Create(5); RE: Constructor and destructor - placement practice test -Atish Shriniwar (06/...
You write a managed (__gc) class that holds a pointer to the native class, you write a constructor and destructor that allocate and destroy the instance, and you write wrapper methods that call the corresponding native C++ member functions. You don't have to wrap all the member functions,...
In particular, if Gadget’s constructor throws, it means that the Gadget object wasn’t created and never existed. So there’s nothing to destroy or dispose: The destructor/disposer not only isn’t needed to run, but it can’t run because it doesn’t have a valid object to run against...
where CMyClass derives from MyInterface (which should be pure interface -- all virtual functions, with no constructor or destructor). The concrete class CMyClass is defined in the DLL, and is not known to the client. The above is essentially what COM does. David Wilkinson | Visual C++ MVP...

This means that an exception thrown from the body of a delegating constructor will cause the destructor to be invoked automati‐ cally. Example: class X { X( int, W ); Y y_; Z z_; public: X(); X( int ); X( W ); }; X::X( int i, W e ) : y_(i), z_(e) { /*...
