3 aspects of an object - CORRECT ANSWER: Name (variable we give it), Attributes

(member data that describe what the object is), Behavior (member functions describe what the object does)

Accessor - CORRECT ANSWER: retrieve data from inside class, typically const,

(show(), display())

Aggregation (or composition) - CORRECT ANSWER: is a relationship between objects, implemented by embedding an object of one class type inside as member data of another class type

Assembly Language - CORRECT ANSWER: symbolic translations of machine code,

easier for people to read

Binary operator - CORRECT ANSWER: two operands, written as stand alone function: operands sent as parameters, member function: first operand is the calling object and the other sent as a parameter

Cin operator overloading - CORRECT ANSWER: friend istream& operator >> )istream& s, *Class*& f);

Class - CORRECT ANSWER: a blueprint for objects, user defined type that describes what a certain type of object will look like, consists of a declaration and a definition

Class declaration - CORRECT ANSWER: shows what an object will look like and what its available functions are, gives an interface 1 / 2

Class definition - CORRECT ANSWER: implementation details, doesn't need to be seen by the user of the interface, consists definitions of its members

Class module consists of - CORRECT ANSWER: Header file and implementation file

checked to insure that correct declarations were made and match(but doesn't match function definitions to call yet), translates to object code, not executable program at this point

Composition - CORRECT ANSWER: refers to a stronger form of aggregation, where the embedded objects would typically not exist independent of the container object

Const - CORRECT ANSWER: 1) not allowed to change, within some scope

2) expresses the intent more clearly to the user 3) affects how certain items can be used

const Member functions - CORRECT ANSWER: the function may not change the calling object itself, can only be done to member functions of a class, member function cant change the member data
