This code has a private destructor, but it will not generate any error because no object is created. #include <iostream> using namespace std; class my_class { private: ~my_class(){ //private destructor } }; int main() { } Example 2 In this program, this will generate a compilation...
In C++, compiler by default creates default constructor for every class. But, if we define our own constructor, compiler doesn’t create the default constructor.A a; B b(a);In the above code, the object ‘b’ (which is created after ‘a’), may use some members of ‘a’ internally...

The pure virtual destructor is possible in C++. If a class contains pure virtual destructor it is must to provide a function body for the pure virtual destructor. Example Code Live Demo #include <iostream> using namespace std; class B { public: virtual ~B()=0; // Pure virtual destructor...
This is my sample code. C++ Copy //main.cpp #pragma once #include "Base.h" #include "Derived.h" int main() { Derived TestObj; return 0; } C++ Copy //Base.h #pragma once #include <iostream> using namespace std; class Base { public: Base() { cout << "Base : cons...
Notice that the following example code prints two destructor messages, one of which is triggered by the explicit user call, and the other is automatically called on program exit. Although, if theMyClassdata member was allocated with thenewoperator in the constructor, this example would have led...

In the worst case this can be a resource leak, if client code does not free the resource.Recommendation If the resource is not being released at all, ensure that the class does release the resource, normally by adding the release to the destructor of the class. This change needs to be ...
