explicit Fraction(double d); // will NOT be used for automatic conversions
everywhere const is applied it... - ANSWERS-expresses an intent on the part of the
programmer, which the compiler enforces (something is not allowed to change
within some scope)
what does a class consist of - ANSWERS-declaration and definition (split into two
files)
what does a struct consist of and how is it different than objects - ANSWERS-
name-the variable name we give it
attributes-data stored inside the struct
,In C data and functions are separate, but in C++ you can build objects that

what are the parts of an object - ANSWERS-Name-the variable name we give it
Attributes-(member data)-the data that describes what the object is
Behavior-(member functions)-behavior aspects of the object (functions that
describe what the object does)
what is a class - ANSWERS-"BLUEPRINT FOR OBJECTS"(you can create many

houses from the same blueprint) -user defined type that describes what a certain
type of object will look like
DDU design - ANSWERS-Declare -- Declaration of class in header file
Define -- Definition of class members in implementation file
Use -- Usage of class by building objects
interface - ANSWERS-what the user sees while the implementation details are
hidden
how can you declare members of a class as - ANSWERS-public (can be accessed
from inside or outside the project) interface
private-can only be used by the object itself
, reasons for dating hiding - ANSWERS--makes interface simpler for user
-principle of lease priveledge (need to know)
-more secure-less chance for misuse (accidental or malicious)
-class implementation easy to change without affecting other modules that use it
class declaration format - ANSWERS-class <className>
{
public:
(public member data and functions go here)
private:
(private member data and functions go here)
};
what are the primary categories of member functions - ANSWERS-mutators-
member functions that can change the state (the member variables inside) of an
object
accessors-member functions that dont change state, aka const member functions
and ARE NOT PERMITTED TO CHANGE THE OBJECT
