General Info: Abstract Class / Abstract Member

An abstract class member is a member that is specified in a class but not implemented. Classes that inherit from the class will have to implement the abstract member. Abstract members are a technique for ensuring a common interface with descendant classes. An abstract class is a class you cannot instantiate. A pure abstract class is a class with only abstract members.

Languages Focus: Abstraction

Abstraction is supported at various levels with each language. A language could enforce abstraction at the class level (either enforcing a no-instantiation rule or a only abstract members rule), and with class members (member methods and/or properties).

C++ Abstraction

AbstractMemberFunction is a pure virtual function makes this class Abstract class indicated by the "=0"and NonAbstractMemberFunction1 is a virtual function.

Syntax Example:
class AbstractClass {
public:
virtual void AbstractMemberFunction() = 0;
  virtual void NonAbstractMemberFunction1();

};

Summary

Abstraction is an important aspect of your software design. To learn more about how abstract classes are similar concepts to interfaces, how they relate to Plato's Forms theory, and more, read our Abstract Members / Class definition article next.
