Difference between Function pointer and Virtual function

Function pointer vs. Virtual function

A function pointer, also called a subroutine pointer or procedure pointer, is a pointer referencing executable code, rather than data. In object-oriented programming such as is often used in C++ and Object Pascal, a virtual function or virtual method is an inheritable and overridable function or method that is dispatched dynamically.

Similarities between Function pointer and Virtual function

Function pointer and Virtual function have 9 things in common (in Unionpedia): C++, Dynamic dispatch, Function (computer programming), Interface (object-oriented programming), Method (computer programming), Object-oriented programming, Pointer (computer programming), Reference (computer science), Virtual inheritance.

C++

C++ (pronounced "C plus plus" and sometimes abbreviated as CPP) is a high-level, general-purpose programming language created by Danish computer scientist Bjarne Stroustrup.

Dynamic dispatch

In computer science, dynamic dispatch is the process of selecting which implementation of a polymorphic operation (method or function) to call at run time.

Function (computer programming)

In computer programming, a function, procedure, method, subroutine, routine, or subprogram is a callable unit of software logic that has a well-defined interface and behavior and can be invoked multiple times.

Interface (object-oriented programming)

In object-oriented programming, an interface or protocol type is a data type that acts as an abstraction of a class.

Method (computer programming)

A method in object-oriented programming (OOP) is a procedure associated with an object, and generally also a message.

Object-oriented programming

Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, which can contain data and code: data in the form of fields (often known as attributes or properties), and code in the form of procedures (often known as methods).

Pointer (computer programming)

In computer science, a pointer is an object in many programming languages that stores a memory address.

Reference (computer science)

In computer programming, a reference is a value that enables a program to indirectly access a particular datum, such as a variable's value or a record, in the computer's memory or in some other storage device.
