An object's virtual method table will contain the addresses of the object's dynamically bound methods. Method calls are performed by fetching the method's address from the object's virtual method table. The virtual method table is the same for all objects belonging to the same class, and is therefore typically shared between them.
In object-oriented programming, when a derived class inherits from a base class, an object of the derived class may be referred to via a pointer or reference of the base class type instead of the derived class type. If there are base class methods overridden by the derived class, the method actually called by such a reference or pointer can be ...
[26] [27] In C++, an abstract class is a class having at least one abstract method given by the appropriate syntax in that language (a pure virtual function in C++ parlance). [25] A class consisting of only pure virtual methods is called a pure abstract base class (or pure ABC) in C++ and is also known as an interface by users of the language. [13]
Suppose a pure virtual method is defined in the base class. If a deriving class inherits the base class virtually, then the pure virtual method does not need to be defined in that deriving class. However, if the deriving class does not inherit the base class virtually, then all virtual methods must be defined.
Online tutoring is the process of tutoring in an online, virtual, or networked, environment, in which teachers and learners participate from separate physical locations. [1] Aside from space, participants can also be separated by time. [2] Online tutoring is practiced using many different approaches for distinct sets of users.
In object-oriented programming, a virtual base class is a nested inner class whose functions and member variables can be overridden and redefined by subclasses of an outer class. [1] Virtual classes are analogous to virtual functions. The run time type of a virtual class depends on the run time type of an object of the outer class.
Following is a list of virtual schools—coursework from an accredited private school or accredited not-for-profit or publicly funded institution, taught primarily through online methods. Schools are listed by country and by state or province.
National Examination Board is responsible for conducting and managing 12th grade-Higher Secondary exams and 10th grade Secondary Education Examination (SEE) Exams. [3] The jurisdiction of the previous Higher Secondary Education Board (HSEB) was limited to 11th and 12th-grade high school (10+2) only. HSEB was established in 1989 under the Higher ...
