Virtual functions:Purpose: To cause late bindingImplementation Method: Use the virtual keyword when declaring a function Pure virtual functions:Objective: To provide abstract InterfacesImplementation Method: Virtual int Foo () = 0;Feature: If a class contains pure virtual functions, the vtable of the class is incomplete, so the object of the class cannot be generated. Such a class is called a pure abstract base class. Pure abstract

The base class Baseoutput explicitly inherits an interface Ioutput, after which the class Trackoutput inherits Baseoutput, and the Ioutput interface is inherited at the same time. Suppose Ioutput has a method output, so there are two output methods in Trackoutput, one from the base class Baseoutput, and one originating from the interface ioutput. This has led to confusion. What to do? Let's look at the foll
