C+ Terminology on Classes member variable or function - Does not belong to any instance of a class. A software entity, specifically an instance of a class, that contains both data and procedures. Class objects are not created in memory until defined a function or class that is not a member of the class but has access to the private members of the class. - The data contained in an object. assignment -each member of one object is copied to its counterpart in the other object. -The procedures an object performs specific to a class. -called whenever a new object is created and initialized with another object's data Combining data and code into a single object. - a standard operator for which it's operation has been redefined when used with - An object's code is not available to code outside the object Code that specifies attributes and member functions defining a type of object. terms that specify how class members may be accesses. class objects. -a special built-n pointer that is available to a class's member functions. It always points to the instance of the class maling the function c - occurs when a class contains an instance of another class. - Can be accessed only by the class member functions Class -classes interact with one another to perform their operation. Can be called from statements outside the class - Used to define a function defined outside the declaration of a class. - A member function that gets a value from a class member variable. allows a new class to be based on an existing class and inherit all the member variables and functions. relationship-when one object is a specialized class of another object -A member function that stores or changes a value of a member function variable. Class from which another class is derived. An object's - The data that is stored in the object's attributes at any given moment. -like private members but can only be accessed by derived classes multiple levels of derived classes. allows an object reference variable or an object pointer to reference objects of different When the value of an item is dependent on other data but may not be updated when it is changed. Class le-A header file that contains a class declaration. types and call the corect functions depending on the object referenced Class fle- A file containing the member function definitions for a class. -Bound to the class during program execution. member finction-when the body of a member function is written inside the class - a class that cannot be instantiated but from which other classes can be derived. -A member function that is automatically called when a class object is created, typically to Word Library: Class Public Virtual member function default constructor header -A constructor that takes no arguments. Copy Constructor -a member function that is automatically called when an object is destroyed, typically overloaded operator access specifier private Abstract base class overloaded function scope resolution operator UML friend data hiding Two or more functions share the same name with different parameter lists Inline State Static this provides a standard method for gr aphically depicting an ohiect oriented member functions class hierarchy of a class- a class with its own copies of the object variable
