	=Classes and Abstraction=		=Classes and Abstraction=
		+	== Knowledge goals==
		+	*To understand the difference between speciﬁcation and implementation of an abstract data type.
		+	*To understand the concepts of encapsulation and abstraction.
		+	*To understand how control and data abstraction facilitate modiﬁability and reuse.
		+	*To understand the basic class design principles.
		+	*To understand how encapsulation and information hiding are enforced by the C++ compiler.
		+	==To be able to==
		+	*Declare a C++ '''class''' type.
		+	*Declare class objects, given the declaration of a '''class''' type.
		+	*Write client code that invokes class member functions.
		+	*Implement class member functions.
		+	*Organize the code for a C++ class into two ﬁles: the speciﬁcation ('''.h''') ﬁle and the implementation ﬁle.
		+	*Write a C++ class constructor.
		+	=ADT - Abstract Data Type=
		+	An Abstract Data Type is a constructed datatype with its functions. Often gathered in a Class. With [[Object Oriented Programming]] it is important to be consequent about the abstraction layers. That will make it easy to understand even very huge and complicated programming projects.
		+	==Why ADT==
		+	The main purpose of ADT is to hide the implementation details, and allow a user of the implementation to abstract from the inner details of the implementation. The black-box theory. Changes in the implementation will not affect the use of the ADT.
		+	===ADT Specification===
		+	The Type specification below of TimeOfDay hides the implementation details and lists the
		+	;TYPE
		+	: TimeOfDay
		+	;DOMAIN
		+	: Each TimeOfDay value is a time of day in the form of hours, minutes, and seconds.
		+	;OPERATIONS
		+	: Create a time object.
		+	: Print (or write) the time.
		+	: Return an object containing the time, incremented by one second.
		+	: Compare two times for equality.
		+	: Determine if one time is "less than" (comes before) another.
