 This approach is known as the Resource Acquisition Is Initialization (RAII) idiom, and is used in languages with deterministic memory management (e.g.C++).In this case, in the example above, the resource is acquired when the file object is created, and when the scope of the variable codice_14 is exited, the file object that codice_14 refers to is destroyed, and as part of this, the resource is released.
