Is it possible to use polymorphism in C programming?

There’s no intrinsic support for polymorphism in C, but there are design patterns, using function pointers, base ‘class’ (structure) casts, etc., that can provide a logical equivalent of dynamic dispatch. The GTK library is good example.

Why is inheritance polymorphism abstraction & encapsulation used?

Why is Inheritance, Polymorphism, Abstraction & Encapsulation used? The main idea behind Object Oriented Programming is simplicity, code reusability, extendibility, and security. These are achieved through Encapsulation, abstraction, inheritance, and polymorphism. For a language to be classified as OOP, it must have these 4 OOP blocks.

What is the difference between inheritance and polymorphism in programming?

The goals of Polymorphism in Object-oriented programming is to enforce simplicity, making codes more extendable and easily maintaining applications. Inheritance allows you to create class hierarchies, where a base class gives its behavior and attributes to a derived class.

What are the basic building blocks of runtime polymorphism?

Almost all implementations of runtime polymorphism in C will use function pointers, so this is the basic building block. Here is a simple example when procedure runtime behavior changes depending on it’s argument.

How do you write polymorphic functions?

You can always write something polymorphic by implementing, say, some vtable technology. It’s just about playing around with function pointers to create a suitable level of indirection. – Kerrek SB

What is the use of function pointers in SQL Server?

Using function pointers you can create virtual tablesand use it to create “objects” that will be treated uniformly, but behave differently at runtime.
