What are abstract classes and interfaces in C++11?
An example of an AI chatbot conversation about C++11 abstract classes and interfaces.
Can you explain what abstract classes are in C++11?
Sure! An abstract class in C++11 is a class that cannot be instantiated and is meant to be a base class. It contains at least one pure virtual function.
What is a pure virtual function?
A pure virtual function is a function declared in a base class that has no implementation. It is defined by assigning 0 in its declaration.
How do interfaces work in C++11?
In C++11, interfaces are typically implemented using abstract classes. An interface is a class that contains only pure virtual functions.
Can you give me an example of an abstract class and an interface?
Certainly! An abstract class could be Shape with a pure virtual function draw(). An interface could be Drawable with the same draw() function.
