RAII (Resource Acquisition Is Initialization)

RAII (Resource Acquisition Is Initialization) is a programming concept where resources like memory, files, or network connections are tied to object lifetimes. When an object is created, it acquires the necessary resource, and when the object is destroyed, it automatically releases the resource. This approach ensures proper resource management without manual intervention, reducing leaks and errors. Essentially, resource management becomes part of the object's lifecycle, making code safer and more predictable.
