(T/F) Class objects can be defined prior to the class declaration.

Falsw

This is automatically called when an object is destroyed.

destructor function

Members of a class object are accessed with the

dot operator

The process of object-oriented analysis can be viewed as the following steps:

identify objects, then define objects' attributes, behaviors, and relationships

Class declarations are usually stored here.

in their own header files

Objects in an array are accessed with ________, just like any other data type in an array.

subscripts

The constructor function always has the same name as

the class

A c++ class is similar to one of these.

structure

This directive is used to create an "include guard," which allows a program to be conditionally compiled. This prevents a header file from accidentally being included more than once.

#ifndef

When you dereference an object pointer, use the

-> operator

(T/F) A destructor function can have zero to many parameters.

False

(T/F) More than one destructor function may be defined for a class.

False

(T/F) The constructor function may not accept arguments.

False

(T/F) You must declare all data members of a class before you can declare member functions

False

(T/F) You must use the private access specification for all data members of a class.

False

(T/F) A private member function is useful for tasks that are internal to the class, but is not directly called by statements outside the class.

True

(T/F) If you do not declare a destructor function, the compiler will furnish one automatically.

True

(T/F) More than one constructor function may be defined for a class.

True

(T/F) OOP is centered around the object, which encapsulate together both the data and the functions that operate on the data.

True

(T/F) One purpose that constructor functions are often used for is to allocate memory that will be needed by the object.

True

(T/F) One purpose that destructor functions are often used for is to free memory that was allocated by the object.

True

(T/F) When an object is defined without an argument list for its constructor, the compiler automatically calls the object's default constructor.

True

(T/F) When using smart pointer to dynamically allocate objects in c++, it is unnecessary to delete the dynamically allocated objects because the smart pointer will automatically delete them.

True

(T/F) Whereas OOP centers on the object, procedural programming center on functions.

True

In OOP terminology, an object's member variables are often called its ________, and its member functions are sometimes referred to as its behaviors, or ________.

attributes, methods

When a member function is defined outside of the class declaration, the function name must be qualified with the:

class name, followed by the scope resolution operator

A ____ is a member function that is automatically called when a class object is ____

constructor, created

A class is a ___ that is defined by the programmer

data type

In a procedural program, you typically ___ stored in a collection of variables, and a set of ___ that perform operations on the date.

data, functions

Objects are created from abstract data types that encapsulate ___ and ___ together.

data, functions

When a constructor function accepts no arguments, or does not have to accept arguments because of default arguments, it is called a(n) ________.

default constructor

Assuming that Rectangle is a class name, the statement Rectangle *BoxPtr;

defined a Rectangle pointer variable called BoxPtr

When the body of a member function is defined inside a class declaration, it is said to be

inline

The constructors function's return type is

none of these

The destructor's return type is

nothing, destructors have no return type

A class may have this many default constructor's

only one

If you do not declare an access specification, the default for members of a class is

private

This type of member function may be called from a statement that is a member of the same class

private

This is used to protect the important data

private access specifier

Examples of access specifiers are the key words:

private and public

This type of member function may be called from a statement outside the clas

public

If a local variable and a global variable have the same name within the same program, the ___ resolution operator must be used.

scope
