  2. Method overriding - Wikipedia

    en.wikipedia.org/wiki/Method_overriding

    The overridden base method must be virtual, abstract, or override. In addition to the modifiers that are used for method overriding, C# allows the hiding of an inherited property or method. This is done using the same signature of a property or method but adding the modifier new in front of it.

  3. Function overloading - Wikipedia

    en.wikipedia.org/wiki/Function_overloading

    Function overloading is usually associated with statically-typed programming languages that enforce type checking in function calls. An overloaded function is a set of different functions that are callable with the same name. For any particular call, the compiler determines which overloaded function to use and resolves this at compile time ...

  4. Virtual function - Wikipedia

    en.wikipedia.org/wiki/Virtual_function

    For this reason, calling virtual functions in constructors is generally discouraged. In C++, the "base" function is called. Specifically, the most derived function that is not more derived than the current constructor or destructor's class is called. [7]: §15.7.3 [8] [9] If that function is a pure virtual function, then undefined behavior occurs.

  5. Factory method pattern - Wikipedia

    en.wikipedia.org/wiki/Factory_method_pattern

    The factory method design pattern solves problems such as: How can an object's subclasses redefine its subsequent and distinct implementation? The pattern involves creation of a factory method within the superclass that defers the object's creation to a subclass's factory method.

  6. Inheritance (object-oriented programming) - Wikipedia

    en.wikipedia.org/wiki/Inheritance_(object...

    By default the subclass retains all of the operations of the base class, but the subclass may override some or all operations, replacing the base-class implementation with its own. In the following Python example, subclasses SquareSumComputer and CubeSumComputer override the transform() method of the base class SumComputer.

  7. Liskov substitution principle - Wikipedia

    en.wikipedia.org/wiki/Liskov_substitution_principle

    Liskov's notion of a behavioural subtype defines a notion of substitutability for objects; that is, if S is a subtype of T, then objects of type T in a program may be replaced with objects of type S without altering any of the desirable properties of that program (e.g. correctness).

  8. Heap overflow - Wikipedia

    en.wikipedia.org/wiki/Heap_overflow

    Exploitation is performed by corrupting this data in specific ways to cause the application to overwrite internal structures such as linked list pointers. The canonical heap overflow technique overwrites dynamic memory allocation linkage (such as malloc metadata) and uses the resulting pointer exchange to overwrite a program function pointer.

  9. Method (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Method_(computer_programming)

    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.
