Description: Indirection is a fundamental concept in programming that refers to a method of accessing data or resources through a reference or pointer. Instead of directly accessing a value or resource, indirection allows a program to use a memory address or identifier that points to the desired resource. This approach provides greater flexibility and efficiency in data management, as it enables the manipulation of complex structures and the implementation of design patterns such as factory or singleton. Indirection is particularly relevant in programming languages that support pointers, such as C and C++, where data in memory can be accessed and modified dynamically. Additionally, in the context of Clean Code, indirection is used to improve the readability and maintainability of code, allowing developers to abstract complex details and focus on the program’s logic. In various software engineering methodologies, indirection also plays a crucial role by facilitating unit testing and code refactoring, as it allows developers to change internal implementation without affecting the public interface of the system.
