Knowledge Check 3 Reviewer

It is the process of formulating general concepts by extracting common properties of instances.

It is an abstraction of its instances.

Class members refer to the following:

_____ members are variables and methods belonging to a class while _____ members are variables and methods belonging to objects.

Private, public and protected are called?

Is one of the best programming methodologies because it defines both the data type and the function that can be applied to it.

It is the process of defining essential concepts while ignoring inessential details.

_____ Abstraction separates the object from the interface from the implementiation, _____ abstraction allow programming langages to have constructs that 'gift wrap very complex and low level instructions into instructions that are much more readable, and _____ abstraction allows OOP langauges to take the concept of abstraction even further and treat programming constructs as discrete objects.

It is the process of hiding an object's implementation from another object, while presenting only the interfaces that should be visible.

_____ are methods that alter the state of an object, ______ are methods that return information about the state of an object.

Interaction and communication with other objects is allowed through messaging.

A/n _____ is a self-contained entity with attributes and behaviors.

Because of the _____ access modifier, members of the same class, subclasses and friend functions may access certain features of the Sample class.

Because of the _____ access modifier, features of the Sample class can only be accessed from within the class itself and from the friend functions.

Because of the _____ access modifier, all classes may access its members of the Sample class..

It is called when an object is created using the new operator or any other process as these methods set the initial state of an object.

Called by using the delete operator as this method de-initializes the state of an object.

_____ is the ability to derive new classes from existing ones.

A _____ inherits the variables and methods of the ______, and may add new variables and methods.

____ is a reference to the current object and can be used to distinguish instance variables from local variables.

It invokes all the constructors in the inheritance hierarchy.

_____ is the process of declaring methods with the same name but different input parameter types.

The process of using the same name with different function signatures is known as _____.

It is an object's ability to behave different depending on its type

It allows a derived class to redefine methods of the same name from the super class.

An overriden method MUST have the following:

Both constructors and destructors can be declared as virtual. The derived class then overrides the base class.

_____ is a template with at least partial implementation that other subclasses are supposed to follow. They are not by themselves suitable for instantiation.

Here one derived class can call more than one base class.

This mechanism can be implemented to avoid ambiguity.

These are user-defined data type, are collections of variables referred to by a single name and can be of different data types.

These are user-defined data type, consists of a set of named constants.

Which operator/s is/are used to connect structure variables with structure elements?

These are the building blocks of a C++ program.

Function declaration is also known as?

This is used as the return type if the function not returning any value.

_____ variables are available only within the function in which they are declared, and only within the block in which they are declared.

_____ variables Variables are available only within the function in which they are declared, and only within the block in which they are declared.

A type of local variable which can only be accessed from the function in which it was declared.

It is is a sequence of either objects or primitives, all of the same type and packaged together under one identifier name.

To refer to a particular element, specify the:

The first element in an array is:

For multi-dimensional arrays, the column is specified before the row as shown: array [column][row]

_____ storage creates and destroys objects automatically at the beginning and end, respectively, of a function or block.

_____ storage creates and destroys objects automatically at the beginning and end, respectively, of a function or block.

_____ storage contains the memory of objects until they are explicitly deleted.

It is a C++ library of container classes, algorithms and iterators; it provides many of the basic algorithms and data structures of computer science.

It is a container that may be used for storing data instead of arrays.

Using vector instead of a pointer-based array can avoid numerous potential memory problems.

It is an object that is used to access members of the container classes, and can be used in a similar mannter to pointers as it allows a programmer to traverse through all the elements of a collection, regardless of its specific implementation.

Which of the following statement/s is/are TRUE about the problems with pointer-based arrays?

The std::vector is a data structure with conguous memory locations. Which of the following state/s about std::vector is/are FALSE?

Pointers can be manipulated like variables, but must be manipulated carefully as they can produce some unexpected results.

Character strings are arrays of characters and always end in null (/0).

In using pointers, utilize the <_____> library to facilitate a number of character manipulations in your programs.

To access individual variables with a pointer, the _____ operator is used.

*Ptr is the _____, the _____ is created with the & operator, and _____ is revealed with the * operator.

Pointers to arrays point to the first element of the array by default, unless they are subscripted or otherwise redirected.

Use _____ to allocate memory and _____ to deallocate memory.

It is an error condition that is created when an object is left on the heap with no pointer variable containing its address.
