What is pure virtual function?

A pure virtual function is implemented by classes which are derived from a Abstract class.
Pure virtual Functions are virtual functions with no definition. They start with virtual keyword and ends with = 0.
Here is the syntax for a pure virtual function,
virtual void f() = 0;

The pure virtual function or virtual method that is required to be implemented by a derived class is not abstract.

A pure virtual function or pure virtual method is a virtual function that is required to be implemented by a derived class if the derived class is not abstract. Classes containing pure virtual methods are termed "abstract" and they cannot be instantiated directly.

An unadulterated virtual capacity or unadulterated virtual strategy is a virtual capacity that is required to be actualized by an inferred class if the determined class isn't extract. Classes containing unadulterated virtual techniques are named "theoretical" and they can't be instantiated specifically.
