C Abstract Classes: Fact or Fiction?

In the C language, there is no concept of abstract classes because C does not support object-oriented features such as abstract classes, inheritance, and polymorphism. Abstract classes are a concept in object-oriented programming languages used to represent a class that can only be inherited and not instantiated. In object-oriented programming languages like C++ and Java, abstract classes are commonly used to define interfaces and specify the behavior of subclasses.

In C language, one can simulate the concepts of classes and methods through structs and function pointers, but there is no concept of abstract classes. If there is a need to implement similar functionality as abstract classes, it can be achieved through conventions and interfaces, but it does not have the strict restrictions and syntax support of abstract classes.
