What is a pure virtual feature?
Almost all types of object -oriented programming (OOP) that create programs and separate parts of the code on "objects" have a function called a pure virtual function that differs from virtual function. Also known as the abstract function, the pure virtual function acts as a surrogate symbol for other variables and takes over information from other features and classes to fill in the gaps. The advantage of using a net virtual feature is that information is tradable and can be changed according to each user. There must be a derived class from which the data is obtained.
The virtual function is similar to a clean variant. Both are able to change depending on the user's input. For example, if the user enters in their name, virtual features will change for the entire program to suit the name of this user. The difference is that virtual features are not dependent on other classes because virtual features have its own body that passes the data of Along data on other classes and features that require information,In this example, the user name.
On the other hand, the pure virtual function has no body. This means that the abstract function itself is unnecessary. It has no own data and if the class is abstract without any information, it can lead to an error. Pure virtual features must have a derived class or class that collects data for an abstract function to work.
A derived class may be a question or area where the user enters a some input, such as a text field. Information from this class is then transferred to all connected clean virtual functions and coordinates the answers. If the abstract function is not explicitly called, it will not be activated if the data is not easy.
Pure virtual functions have several advantages. Using an abstract function instead of creataine the entire coding organ significantly limits the amount of code that a programmer must create, especially for large PRograms that use the same information continuously. The abstract function can also be tuned by a programmer to change the way the program processes data to be more efficient. Information is based on derived classes, so programs with questions and complex input adjusts the data to the user input without accidentally calling another part of the irrelevant code.
