The syntax for an abstract class with struct will be as follows: struct className{ virtual return_type fun_name()=0;} We cannot create an object. We can still create a constructor for the abstract class. To call the constructor, we use constructor chaining. The basic purpose of using abst...
Does C++ compiler create default constructor when we write our own?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);...
(UPDATE: I apparently triggered an undefined behavior in C++ that no compiler warned me about, see more details here: https://stackoverflow.com/questions/63951270/using-default-copy-constructor-corrupts-a-tree-in-c ). (UPDATE: I think I solved that problem.) While the code builds cleanly ...

Q: What is constructor or ctor? A: Constructor creates an object and initializes it. It also creates vtable for virtual functions. It is different from other methods in a class. Q: What about Virtual Destructor? A: Yes there is a Virtual Destructor. A destructor can be virtual as it is...

Like methods, events can be virtual, overridden, abstract, or sealed. Events can also be static: public class Foo { public static event EventHandler<EventArgs> StaticEvent; public virtual event EventHandler<EventArgs> VirtualEvent; } Lambda Expressions ...
There is a high possibility that the operation of the program will be interrupted. I want to call a virtual function that handles a member within a derivative class constructor, a destructor. Even if I pay attention to the initialization order (by initializing members after the virtual function...
Previously, only user-provided constructors would disqualify a class from being an aggregate. This change puts more restrictions on how such types can be initialized.The following code compiles without errors in Visual Studio 2017 but raises errors C2280 and C2440 in Visual Studio 2019 under /...
