Parameters (none) Return value (none) Postconditions Resource acquisition is initialization (RAII) is a programming idiom used in several object-oriented, statically-typed programming languages to describe a particular language behavior. In RAII, holding a resource is a class invariant, and is tied to object lifetime. Resource allocation (or acquisition) is done during object creation (specifically initialization), by the constructor, while resource deallocation (release) is done during object destruction (specifically finalization), by the cheap flights from clt to mke
