Computer Programming

Data abstraction is the means by which we lift the level of abstraction away from the machine (low-level) and closer to the application domain (high-level). As far as the machine is concerned, all data is binary, however the exact same binary representation can mean entirely different things within different contexts. Abstraction allows us to separate these contexts and thus give much greater meaning to the underlying representation.

PASCAL has 3 definitions actually. They are:-

1. Programming Language Based For Blaise Pascal.

2. Pedantry and Strictness Created A Language.

3. Philips Automatic Source Calculator.

Machine language is nothing but numeric codes. Because humans have a difficult time remembering numeric codes, manufacturers of microprocessors create mnemonics; these sets of mnemonics are called assembly language. Each processor family has its own set of mnemonics, or assembly language, so assembly for the Intel processor used in many PCs is different from the assembly for a Motorola processor. In fact the assembly for different processors made by the same manufacturer will have assembly that differs, sometimes by a little, sometimes significantly. A quick example of one type of Motorola assembly, to clear 10 32-bit memory locations might look like this:

movea #$6000,ao

move.l #10,d7

10$

clr.l (a0+)

subq.l #1,d7

bne.s 10$

rts

You copy a singly linked list into a doubly linked list by iterating over the singly linked list and, for each element, calling the doubly linked list insert function.

A Standard can be defined as a set of technical definitions and guidelines that
function as instructions for designers, manufacturers, operators, or users of
equipment.


A standard becomes a Code when it has been adopted by one or more
governmental bodies and is enforceable by law, or when it has been incorporated
into a business contract.

example of procedural programming are those programming language that have structure e.g basic,fortran,c++,c and pascal e.t.c

Well first off, you need to know how to spell programmer. (you spelled it wrong).

J.K.

You must have a knowledge of the programming language.

Ex. C#, C++,.NET,Flash, Java.

You must have a sense of logic, and be good at math and physics.

HTML, the HyperText Markup Language, defines web pages' content; CSS, Cascading Style Sheets, defines the web pages' presentation; and JavaScript, defines interactivity with the user, creating "Rich Internet Applications" (RIA).

1-6 sequence numbers.

7 (*) for comment (-) for continue (D) for debugging.

8-11 called as Area-A in this Area we can write

Divisions,Paragraphs,sections,Level numbers.

12-72 called as Area-B in this area we can write cobol

executable statements like select,accept,display.

73-80 is ignored area by compiler but we can see in source

Listing.

In object-oriented programming, inheritance allows the creation of is-a relationships. For example, a car is a vehicle, and a bike is a vehicle, so those could be modeled through a vehicle class, and a pair of car and bike classes, both derived from (inheriting from) the vehicle class. Derived classes like car and bike share common vehicle properties, such as speed, location, direction, number of wheels, etc.

//This program swaps the values in the variable using function containing reference arguments

#include<iostream.h>

void swap(int &iNum1, int &iNum2);

void main()

{

int iVar1, iVar2;

cout<<"Enter two numbers "<<endl;

cin>>iVar1;

cin>>iVar2;

swap(iVar1, iVar2);

cout<<"In main "<<iVar1<<" "<<iVar2<<endl;

}

void swap(int &iNum1, int &iNum2)

{

int iTemp;

iTemp = iNum1;

iNum1 = iNum2;

iNum2 = iTemp;

cout<<"In swap "<<iNum1<<" "<<iNum2<<endl;

}

Reference arguments are indicated by an ampersand (&) preceding the argument:

int &iNUm1;

the ampersand (&) indicates that iNum1 is an alias for iVar1 which is passed as an argument.

The function declaration must have an ampersand following the data type of the argument:

void swap(int &iNum1, int &iNum2)

The ampersand sign is not used during the function call:

swap(iVar1, iVar2);

The sample output is

Enter two numbers

12

24

In swap 24 12

In main 24 12

manual data input is cheap

The compiler converts source code (the stuff the programmer wrote and is human readable) and converts it to machine code that the computers CPU can understand. The conversion is used to make an executable program.

The compiler can also make libraries but libraries are not executable by them selves.

A public class is a base class declared with public inheritance:

class base {

// ...

};

class derived : public base {

// ...

};

In the above example, base is a public class of derived, thus derived is regarded as being a type of base. The derived class inherits all the public and protected methods of its base. Protected methods are accessible to the derived class, its derivatives and their friends.

If base were declared protected, its public methods become protected methods of derived. The base class is then an implementation detail of derived; only members of derived, its derivatives and their friends can treat derived as being a type of base.

If declared private, the public and protected methods of base become private methods of derived. The base class is then an implementation detail of derived; only members of derived and its friends can treat derived as a type of base.

Data inconsistency exists when different and conflicting versions of the

same data appear in different places. Data inconsistency creates

unreliable information, because it will be difficult to determine which

version of the information is correct. (It's difficult to make correct - and

timely - decisions if those decisions are based on conflicting information.)

Data inconsistency is likely to occur when there is data redundancy. Data

redundancy occurs when the data file/database file contains redundant -

unnecessarily duplicated - data. That's why one major goal of good

database design is to eliminate data redundancy.

• Hypertext - Hypertext is basically the same as regular text - it can be stored, read, searched, or edited - with an important exception: hypertext is text with pointers to other text. The browsers let you deal with the pointers in a transparent way -- select the pointer, and you are presented with the text that is pointed to.
• Hypermedia - Hypermedia is a superset of hypertext. Hypermedia documents contain links not only to other pieces of text, but also to other forms of media - sounds, images, and movies. Images themselves can be selected to link to sounds or documents. This means that browsers might not display a text file, but might display images or sound or animations. Hypermedia simply combines hypertext and multimedia.

A superclass, also referred to as a parent class, is a class what which other classes are derived from. These derived classes are known as either subclasses or child classes.

a. OOP provides a clear modular structure for programs which makes it good for defining abstract datatypes where implementation details are hidden and the unit has a clearly defined interface.

b. OOP makes it easy to maintain and modify existing code as new objects can be created with small differences to existing ones.

c. OOP provides a good framework for code libraries where supplied software components can be easily adapted and modified by the programmer. This is particularly useful for developing graphical user interfaces.
