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...

cleanup operations. Destructors provide appropriate safeguards, such as automatically calling the base type's destructor. In C# code, Object..::.Finalize cannot be called or overridden. I think Xarx just made a typo. I think Xarx meant to say "in C++ the syntax". I'll fix i...
https://learn.microsoft.com/cpp/cppcx/ref-classes-and-structs-c-cx?view=msvc-170 I saw the following in this link. The behavior of trying to access a member of a class that has already allowed the destructor to run is not defined. There is a high…
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 ...
