• RAII is a programming paradigm in C++ for resource management, and it is considered one of the most important and powerful techniques in modern C++ programming

RAII can be summarized as follows:

• encapsulate each resource into a class, where

  • the constructor acquires the resource and establishes all class invariants or throws an exception if that cannot be done, • the destructor releases the resource and never throws exceptions;

• always use the resource via an instance of a RAII-class that either

  • has automatic storage duration or temporary lifetime itself, or • has lifetime that is bounded by the lifetime of an automatic or temporary object.

→ The whole idea is that the acquired resources during initialization of an object gets released when the object goes out of scope

RAII Features

• Automatic Cleanup: Resources are automatically cleaned up when the object goes out of scope
• Exception Safety: The destructor of the acquired object is called even if the exception is thrown, which ensures exceptions are thrown and resources are freed
• Scope-Based Management: Resources are tied to the lifetime of objects and are released when these objects go out of scope
