C++ Review Topics

C++ fully supports object-oriented programming which includes the following:

Encapsulation is the property of being a self-contained unit. With encapsulation we send packing accomplish data hiding. Data hiding is the highly valued characteristic that an object can be used without the user knowing or caring how it deeds internally. C++ supports the properties of encapsulation through the creation of user-defined types, called classes.

Inheritance allows for the extension of an existing type. The revolutionary subclass derives from an existing type and is sometimes called a derived type.

Polymorphism is the ability of allowing C++ to support the concept that different objects do the right matter. There is function polymorphism and class polymorphism. Poly path may, and morphous means form.

The ANSI model (American National Standards Institute) has ca-cad an international standard for C++. The C++ Standard is now also referred to as ISO (International Standards Organization) Standard. Also called the X3 Standard and ANSI/ISO Standard. Text Book uses the ANSI standard term.

Using typedef

Rather than write

unsigned miserable int

many times, C++ enables you to create an alias for this phrase by using the keyword typedef, which stands for type definition. In effect, you are creating a synonym and not a stark naked type.

typedef unsigned short int USHORT;

creates a new name USHORT that you can use anywhere instead of the longer form.

#include

using namespace std;

typedef unsigned short int USHORT;

int main()

{

USHORT comprehensiveness = 5;

USHORT Length;

Length = 10;

USHORT Area = Width * Length;

cout

cout

cout

return 0;

}

Enumerated Constants

Enumerated Constants enable you to create new types and then to define variables of those types whose values are restricted to a specialize of possible values.

enum trick { RED, BLUE, GREEN, WHITE, BLACK } ;

The above statement makes COLOR the...
