Detailed Explanation of Virtual Functions in C++

C++ virtual functions are member functions that are redefined in derived classes. They are declared using the virtual keyword. This is used to inform the compiler to perform dynamic linking or late binding on the function. It is necessary to use a single pointer to reference all objects of different classes. Thus, we create a … Read more

What Is C++?

What Is C++?

C++ is a high-level programming language that is an extension of C language. C++ supports both procedural programming, characteristic of C language, and object-oriented programming, characterized by abstract data types. It also supports object-oriented programming features like inheritance and polymorphism. C++ excels in object-oriented programming while still allowing for procedural programming. Features: Compatibility with C … Read more

Introduction to PWN: Understanding Type Confusion

What Is Type Confusion? In high-level programming languages, a variable typically consists of three parts: data type, type name, and value. The type name serves as a marker for distinguishing variables in the programming language (for example, in C, local variable names within a function cannot be repeated within the same scope). The value is … Read more

Deep Dive Into C++ Virtual Function VTable: The Hero of Polymorphism

C++’s polymorphism is one of its most powerful features and a cornerstone of object-oriented programming. Through polymorphism, we can call derived class functions using base class pointers or references without needing to know the specific derived class type. So, how is this “magic” achieved? The answer lies in the virtual table (vtable)! It is the … Read more
