C++ also allows a single instance of the multiple class to be created via the virtual inheritance mechanism (i.e. Worker::Human and Musician::Human will reference the same object). Common Lisp CLOS attempts to provide both reasonable default behavior and the ability to override it.
Many object-oriented programming languages permit a class or object to replace the implementation of an aspect—typically a behavior—that it has inherited. This process is called overriding . Overriding introduces a complication: which version of the behavior does an instance of the inherited class use—the one that is part of its own class ...
Off-by-one errors are common in using the C library because it is not consistent with respect to whether one needs to subtract 1 byte – functions like fgets() and strncpy will never write past the length given them (fgets() subtracts 1 itself, and only retrieves (length − 1) bytes), whereas others, like strncat will write past the length given them.
A method in object-oriented programming (OOP) is a procedure associated with an object, and generally also a message.An object consists of state data and behavior; these compose an interface, which specifies how the object may be used.

Virtual inheritance is a C++ technique that ensures only one copy of a base class ' s member variables are inherited by grandchild derived classes. Without virtual inheritance, if two classes B and C inherit from a class A , and a class D inherits from both B and C , then D will contain two copies of A ' s member variables: one via B , and one ...
Object-Oriented Software Construction, also called OOSC, is a book by Bertrand Meyer, widely considered a foundational text of object-oriented programming. [citation needed] The first edition was published in 1988; the second edition, extensively revised and expanded (more than 1300 pages), in 1997.
Multiple choice questions lend themselves to the development of objective assessment items, but without author training, questions can be subjective in nature. Because this style of test does not require a teacher to interpret answers, test-takers are graded purely on their selections, creating a lower likelihood of teacher bias in the results. [8]
