• Constructors cannot be virtual. • Constructors cannot be inherited, although a derived class can call the constructor of a base class.· The various types of Constructor are as follows: Default Constructor: Default Constructor is also called as Empty Constructor which has no arguments and...
Overloading– Constructors can be overloaded, allowing multiple constructors with different parameter lists. Virtual Declaration– Constructors cannot be declared virtual, which distinguishes them from other member functions. Address Reference– The addresses of constructors cannot be directly referred to. ...
This cannot be done with a constructor. As jsmith said, constructors cannot be virtual. This is because you need to know what kind of object you have before the constructor is called. If I'm understanding right... the end result is you want to do something like this: ...
You can use a constructor to initialize a const or volatile object, but the constructor itself cannot be declared as const or volatile. The only legal storage class for a constructor is inline; use of any other storage-class modifier, including the __declspec keyword, with a constructor causes...

Virtual Functions in Constructors We recommend that you be careful when you call virtual functions in constructors. Because the base class constructor is always invoked before the derived class constructor, the function that's called in the base constructor is the base class version, not the deriv...
It is implicitly declared or explicitly defaulted . Ahas no virtual functions and no virtual base classes All the direct base classes ofAhave trivial constructors The classes of all the nonstatic data members ofAhave trivial constructors
Is virtual a Java modifier? Java interface methods are all virtual. They must be virtual because they rely on the implementing classes to provide the method implementations. The code to execute will only be selected at run time. Example with virtual functions with abstract classes. ...

A mem‐initializer‐id for the hidden base class may be specified using a qualified name. —end note ] Unless the mem‐initializer‐id names a non‐static data member of the constructor’s class, the constructor’s class, or a direct or virtual base of that class, the mem‐initializer ...
