Multiple inheritance is a feature of some object-oriented computer programming languages in which a class can inherit characteristics and features from more than one superclass. It is distinct to single inheritance, where a class may only inherit from one particular superclass.
Languages that support multiple inheritance include C++, Common Lisp via the Common Lisp Object System, Perl and Python.
Multiple inheritance has been a touchy issue for many years, with opponents pointing to its increased complexity and ambiguity in situations such as the "diamond problem", where it may be ambiguous as to which superclass a particular feature is inherited from if more than one superclass implements said feature. This can be addressed in various ways, including using virtual inheritance.

Famous quotes containing the words multiple and/or inheritance:
“Combining paid employment with marriage and motherhood creates safeguards for emotional well-being. Nothing is certain in life, but generally the chances of happiness are greater if one has multiple areas of interest and involvement. To juggle is to diminish the risk of depression, anxiety, and unhappiness.”
—Faye J. Crosby (20th century)
“Late in the afternoon we passed a man on the shore fishing with a long birch pole.... The characteristics and pursuits of various ages and races of men are always existing in epitome in every neighborhood. The pleasures of my earliest youth have become the inheritance of other men. This man is still a fisher, and belongs to an era in which I myself have lived.”
—Henry David Thoreau (1817–1862)
