How do you call a superclass constructor?

To explicitly call the superclass constructor from the subclass constructor, we use super() . It's a special form of the super keyword. super() can be used only inside the subclass constructor and must be the first statement.

How do you call a parent class constructor?

Call super(). __init__(args) within the child class to call the constructor of the immediate parent class with the arguments args . If a child class directly inherits from more than one parent class, the constructor of the first class in the list of parent classes will be called.

How do you call a superclass constructor in C++?

If you want to call a superclass constructor with an argument, you must use the subclass's constructor initialization list. Unlike Java, C++ supports multiple inheritance (for better or worse), so the base class must be referred to by name, rather than "super()".

Are constructors inherited C++?

Historically constructors could not be inherited in the C++03 standard. You needed to inherit them manually one by one by calling base implementation on your own.

Can you use this () and super () both in a constructor?

We can use super() as well this() only once inside constructor. If we use super() twice or this() twice or super() followed by this() or this() followed by super(), then immediately we get compile time error i.e, we can use either super() or this() as first statement inside constructor and not both.

Can abstract class have constructor?

The constructor inside the abstract class can only be called during constructor chaining i.e. when we create an instance of sub-classes. This is also one of the reasons abstract class can have a constructor.
