Document Summary
Cse 278 - lecture - inheritance and object oriented programming. Languages like pascal and c facilitated development of structured programs. Need for ability to extend and reuse software became obvious which led to object-oriented programming. C++ has become most widespread object oriented language in the world. Data and basic operations for processing this data are encapsulated into a single entity. This is made possible with programming elements like libraries, packages, classes, and units/modules. The unit of encapsulation in oop is the class. Client code must only use public operations, so that implementation may be changed without affecting client code. A class can be derived from another class. There is no need to change or add code since the new class can use them. Can use classes that are base classes and can be derived to simply represent multiple things (person represents student and faculty). Public: may be accessed by any function. Private: only accessed by member functions and friends.
