Method pointers are a programming concept that allows a program to reference a specific method within a class. This enables developers to create more flexible and reusable code by passing methods as arguments or storing them in data structures. In languages like C++ and Java, method pointers can be used to invoke methods dynamically, enhancing the functionality of applications. In C#, method pointers are often referred to as delegates. They provide a way to encapsulate a method call, allowing for event handling and callback mechanisms. By using method pointers, programmers can create more modular code, making it easier to maintain and extend applications over time.
