Using single inheritance, a subclass can inherit from only one superclass. Continuing the example given above, a Person object can be either a Student or an Employee , but not both. Using multiple inheritance partially solves this problem, as one can then define a StudentEmployee class that inherits from both Student and Employee .

Doxygen supports output in many formats including: HTML, CHM, RTF, PDF, LaTeX, PostScript and man page. Doxygen can generate inheritance diagrams for C++ classes. For more advanced diagrams and graphs, Doxygen can use the "dot" tool from Graphviz. [15]
The bridge uses encapsulation, aggregation, and can use inheritance to separate responsibilities into different classes. When a class varies often, the features of object-oriented programming become very useful because changes to a program 's code can be made easily with minimal prior knowledge about the program.

Not all languages support multiple inheritance. For example, Java allows a class to implement multiple interfaces, but only inherit from one class. [22] If multiple inheritance is allowed, the hierarchy is a directed acyclic graph (or DAG for short), otherwise it is a tree. The hierarchy has classes as nodes and inheritance relationships as links.
The singly rooted hierarchy, in object-oriented programming, is a characteristic of most (but not all) OOP-based programming languages.In most such languages, in fact, all classes inherit directly or indirectly from a single root, usually with a name similar to Object; all classes then form a common inheritance hierarchy.
Class diagram showing generalization between the superclass Person and the two subclasses Student and Professor. The generalization relationship—also known as the inheritance or "is a" relationship—captures the idea of one class, the so-called subclass, being a specialized form of the other (the superclass, super type, or base class).
