A class defines a data structure that can contain both data and functions as members. An object is an instance of a class that allocates memory for the class's data members. Classes allow the declaration of multiple objects that each have their own copies of the class's data members and can access the class's member functions. Constructors initialize an object's data members when it is created, while destructors perform cleanup tasks when an object is destroyed.
