Can you call a destructor C++?

When you throw from the constructor, it will call the destructor of any object constructed so far : the member variables and the inherited classes (section 15.2/2). If you call the destructor manually, their destructor will be also called (section 12.4/8).

No. You never need to explicitly call a destructor (except with placement new ) . A class’s destructor (whether or not you explicitly define one) automagically invokes the destructors for member objects. They are destroyed in the reverse order they appear within the declaration for the class.

Use the obj. ~ClassName() Notation to Explicitly Call a Destructor Function . Destructors are special functions that get executed when an object goes out of scope automatically or is deleted by an explicit call by the user.4 Nis 2021
