According to the Rule of Five, a type must possess all five of the following if any of them are ever required. Move the constructor, copy the assignment, then copy the destructor.

The Rule of Five states that if a type ever needs one of the following, then it must have all five. copy constructor. copy assignment. destructor. move constructor.

In C++, the rule of three and the rule of five are general guidelines for creating exception-safe code and formalizing resource management conventions. The guidelines outline how to methodically accomplish these objectives using a class’s default members.

1. Constructor (1): Default constructor.
2. Constructor (2): Copy constructor.
3. Constructor (3): Move constructor.
4. Destructor: Destructor is responsible for releasing resources (e.g., memory) allocated by the class.
5. Assignment operator (copy assignment): Overloading the assignment operator for copying objects.
