400 GB DVD

Pioneer Released 400 GB DVD

Soon there will be a phase out of those 3.5 GB DVD that you are always using when burning DVD movies.
Pioneer has released on what they claim as the world’s first 16-layer optical disc. With 400 GB Capacity [ An ordinary 3.5 GB DVD ) is only Single Layer.
Right now the technology is Read Only but I do believed that soon they will release the Re-write version of this DVD. But how much will the machine to rewrite this DVD cost?
Let us see what will happen next. Maybe I have to go back to this post after a year?
Anyway, it is really great that Technology is advancing. Just imagine if your regular DVD could hold about 4 movies, this DVD would hold about 200 + Movies.

VISUAL STUDIO 2008 Advantages

Introduction
Visual Studio 2008 code name "Orcas" Beta 2 has just hit the road and, since it is Beta 2, this means Visual Studio 2008 is feature complete and is ready for RTM. Below, we would find a brief introduction of some of the new features introduced with VS 2008 and .NET 3.5 Beta 2.
A quick list of some of the new features are:
Multi-Targeting support
Web Designer and CSS support
ASP.NET AJAX and JavaScript support
Project Designer
Data
LINQ – Language Integrated Query
The features listed and explained in this paper are not complete and this document intends to give you a forehand to start off with VS 2008.
1. Multi-Targeting Support
Earlier, each Visual Studio release only supported a specific version of the .NET Framework. For example, VS 2003 only works with .NET 1.1, and VS 2005 only works with .NET 2.0.
One of the major changes with the VS 2008 release is to support what Microsoft calls "Multi-Targeting". This means that Visual Studio will now support targeting multiple versions of the .NET Framework, and developers will be able to take advantage of the new features that Visual Studio provides without having to migrate their existing projects and deployed applications to use a new version of the .NET Framework.
Now when we open an existing project or create a new one with VS 2008, we can pick which version of the .NET Framework to work with. The IDE will update its compilers and feature-set to match the chosen .NET Framework.
Features, controls, projects, item-templates, and references that do not work with the selected version of the Framework will be made unavailable or will be hidden.
Unfortunately, support has not been included to work with Framework versions 1.1 and earlier. The present release supports 2.0/3.0 and 3.5 .NET Frameworks.
Microsoft plans to continue multi-targeting support in all future releases of Visual Studio.
Creating a New Project with Visual Studio 2008 that Targets .NET 2.0 Framework Library
The screenshots below depict the creation of a new web application targeting .NET 2.0 Framework. Choose File->New Project. As we see in the snapshot below in the top-right of the new project dialog, there is now a dropdown that allows us to choose which versions of the .NET Framework we want to target when we create the new project. The templates available are filtered depending on the version of the Framework chosen from the dropdown:

Can I Upgrade an Existing Project to .NET 3.5?
When we open a solution created using an older version of Visual Studio and Framework, VS 2008 would ask if migration is required. If we opt to migrate, then a migration wizard would start. If we wish to upgrade our project to target a newer version of the Framework at a later point of time, we can pull up the project properties page and choose the Target Framework. The required assemblies are automatically referenced. The snapshot below shows the properties page with the option Target Framework marked.
2. Web Designer, Editing and CSS Support
One feature that web developers will discover with VS 2008 is its drastically improved HTML designer, and the extensive CSS support made available.
The snapshots below depict some of the new web designer features in-built into VS 2008.
Split View Editing
In addition to the existing views, Design view and Code view, VS 2008 brings along the Split view which allows us to view both the HTML source and the Design View at the same-time, and easily make changes in any of the views. As shown in the image below, as we select a tag in code view, the corresponding elements/controls are selected in design view.
CSS Style Manager
VS 2008 introduces a new tool inside the IDE called "Manage Styles". This shows all of the CSS style sheets for the page.
It can be used when we are in any of the views - design, code and split views. Manage Styles tool can be activated by choosing Format -> CSS Styles -> Manage Styles from the menu. A snapshot of the same would look like the following:
Create a new style using the new style dialog window as show in the snapshot below.
Now, the style manager would show .labelcaption style as well in the CSS styles list. However, if we observe that the body element has a circle around it but the .labelcaption does not have one, this is because the style is not in use yet.
We will not select all the labels below and apply our new style .labelcaption.
We can choose to modify the existing style through GUI using "Modify style..." menu option in the dropdown menu as shown above or choose to hand edit the code by choosing the option "Go To Code".
CSS Source View Intellisense
The designer is equipped with the ability to select an element or control in design-view, and graphically select a rule from the CSS list to apply to it.
We will also find when in source mode that we now have intellisense support for specifying CSS class rules. The CSS Intellisense is supported in both regular ASP.NET pages as well as when working with pages based on master pages.
Code Editing Enhancements
Below is a non-exhaustive list of a few new code editing improvements. There are many more about which I don't know yet.
Transparent Intellisense Mode
While using VS 2005/2003 we often find ourselves escaping out of intellisense in order to better see the code around, and then go back and complete what we were doing.
VS 2008 provides a new feature which allows us to quickly make the intellisense drop-down list semi-transparent. Just hold down the "Ctrl" key while the intellisense drop-down is visible and we will be able to switch it into a transparent mode that enables us to look at the code beneath without having to escape out of Intellisense. The screenshot below depicts the same.
Organize C# Using Statements
One of the small, but a nice new feature in VS 2008 is support for better organizing using statements in C#. We can now select a list of using statements, right-click, and then select the "Organize Usings" sub-menu. When we use this command the IDE will analyze what types are used in the code file, and will automatically remove those namespaces that are declared but not required. A small and handy feature for code refactoring.
3. ASP.NET AJAX and JavaScript Support
JavaScript Intellisense
One new feature that developers will find with VS 2008 is its built-in support for JavaScript Intellisense. This makes using JavaScript and building AJAX applications significantly easier. A double click on HTML control in design mode would automatically create a click event to the button and would create the basic skeleton of the JavaScript function. As we see in the depicted image below, JavaScript Intellisense is inbuilt now. Other JavaScript Intellisense features include Intellisense for external JavaScript libraries and adding Intellisense hints to JavaScript functions.
JavaScript Debugging
One new JavaScript feature in VS 2008 is the much-improved support for JavaScript debugging. This makes debugging AJAX applications significantly easier. JavaScript debugging was made available in VS 2005 itself. However, we had to run the web application first to set the breakpoint or use the "debugger" JavaScript statement.
VS 2008 makes this much better by adding new support that allows us to set client-side JavaScript breakpoints directly within your server-side .aspx and .master source files.
We can now set both client-side JavaScript breakpoints and VB/C# server-side breakpoints at the same time on the same page and use a single debugger to step through both the server-side and client-side code in a single debug session. This feature is extremely useful for AJAX applications. The breakpoints are fully supported in external JavaScript libraries as well.
4. Few Other Features and Enhancements
Below is a list of few other enhancements and new features included in Microsoft Visual Studio 2008.
Project Designer
Windows Presentation Foundation (WPF) applications have been added to Visual Studio 2008. There are four WPF project types:
WinFX Windows Application
WinFX Web Browser Application
WinFX Custom Control Library
WinFX Service Library
When a WPF project is loaded in the IDE, the user interface of the Project Designer pages lets us specify properties specific to WPF applications.
Data
Microsoft Visual Studio 2008 Beta 2 includes the following new features to incorporate data into applications:
The Object Relational Designer (O/R Designer) assists developers in creating and editing the objects (LINQ to SQL entities) that map between an application and a remote database
Hierarchical update capabilities in Dataset Designer, providing generated code that includes the save logic required to maintain referential integrity between related tables
Local database caching incorporates an SQL Server Compact 3.5 database into an application and configures it to periodically synchronize the data with a remote database on a server. Local database caching enables applications to reduce the number of round trips between the application and a database server
LINQ – Language Integrated Query
LINQ is a new feature in VS 2008 that broadens great querying capabilities into the language syntax. LINQ introduces patterns for querying and updating data. A set of new assemblies are provided that enable the use of LINQ with collections, SQL databases, and XML documents.
Visual Studio 2008 Debugger
The Visual Studio 2008 debugger has been enhanced with the following features:
Remote debugging support on Windows Vista
Improved support for debugging multithreaded applications
Debugging support for LINQ programming
Debugging support for Windows Communications Foundation
Support for script debugging, including client-side script files generated from server-side script now appear in Solution Explorer
Reporting
Visual Studio 2008 provides several new reporting features and improvements such as:
New Report Projects: Visual Studio 2008 includes two new project templates for creating reporting applications. When we create a new Reports Application project, Visual Studio provides a report (.rdlc) and a form with a ReportViewer control bound to the report.
Report Wizard: Visual Studio 2008 introduces a Report Wizard, which guides us through the steps to create a basic report. After we complete the wizard, we can enhance the report by using Report Designer.
Expression Editor Enhancement: The Expression Editor now provides expressions that we can use directly or customize as required.
PDF Compression: The ReportViewer controls can now compress reports that are rendered or exported to the PDF format.

OBJECT ORIENTED PROGRAMING CONCEPT

Why Object Oriented approach?
A major factor in the invention of Object-Oriented approach is to remove some of the flaws encountered with the procedural approach. In OOP, data is treated as a critical element and does not allow it to flow freely. It bounds data closely to the functions that operate on it and protects it from accidental modification from outside functions. OOP allows decomposition of a problem into a number of entities called objects and then builds data and functions around these objects. A major advantage of OOP is code reusability.
Some important features of Object Oriented programming are as follows:
Emphasis on data rather than procedure
Programs are divided into Objects
Data is hidden and cannot be accessed by external functions
Objects can communicate with each other through functions
New data and functions can be easily added whenever necessary
Follows bottom-up approach

Concepts of OOP:
Objects
Classes
Data Abstraction and Encapsulation
Inheritance
Polymorphism

Briefly on Concepts:

Objects
Objects are the basic run-time entities in an object-oriented system. Programming problem is analyzed in terms of objects and nature of communication between them. When a program is executed, objects interact with each other by sending messages. Different objects can also interact with each other without knowing the details of their data or code.

Classes
A class is a collection of objects of similar type. Once a class is defined, any number of objects can be created which belong to that class.

Data Abstraction and Encapsulation
Abstraction refers to the act of representing essential features without including the background details or explanations. Classes use the concept of abstraction and are defined as a list of abstract attributes.Storing data and functions in a single unit (class) is encapsulation. Data cannot be accessible to the outside world and only those functions which are stored in the class can access it.

Inheritance
Inheritance is the process by which objects can acquire the properties of objects of other class. In OOP, inheritance provides reusability, like, adding additional features to an existing class without modifying it. This is achieved by deriving a new class from the existing one. The new class will have combined features of both the classes.

Polymorphism
Polymorphism means the ability to take more than one form. An operation may exhibit different behaviors in different instances. The behavior depends on the data types used in the operation. Polymorphism is extensively used in implementing Inheritance.

Advantages of OOP

Object-Oriented Programming has the following advantages over conventional approaches:
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.
OOP makes it easy to maintain and modify existing code as new objects can be created with small differences to existing ones.
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.

main() / void main() / int main() / int main(void) / int main(int argc, char *argv[])

=================================================
main() / void main() / int main() / int main(void) / int main(int argc, char *argv[])


A very common question is "What's the difference between void main and int main?". This particular FAQ tries to answer that and more, covering other versions of the main() implementation.
The first thing to note is that this is one of those topics that people seem to like to argue over for hours, days and more. Some arguments are valid, some are not, and some are just plain old opinion.
The C and C++ standards differ when it comes to main(), so I'll detail each one separately.
For C
Under C89, main() is acceptable, although it is advisable to use the C99 standard, under which only these are acceptable:
int main ( void )int main ( int argc, char *argv[] )
Slight variations of the above are acceptable, where int can be replaced by a typedef name defined as int, or the type of argv can be written as char ** argv, and so on.
The first option is used when you do not require access to the command line arguments.
The names argc and argv are identifiers that can be changed if you so desire, but sticking to argc/argv is convention.
The return type of main() must always be an int, this allows a return code to be passed to the invoker.
Under C89, the return statement at the end of main() is required, whereas under C99 if no return statement is present, return 0 is implied. However, it is good programming practice to always use a return statement, even if you don't have to.
For C++
The following are acceptable uses:
int main ( int argc, char *argv[] )int main ()
The first option follows similar conventions to those used by C99.
The second option is used when you do not require access to the command line arguments, and is equivalent to the int main(void) option used by C99.
Again, the return type must always be an int, and the function should return 0; at the end, but it is not required by the standard.
(C) The difference between int main() and int main(void)
A common misconception for C programmers, is to assume that a function prototyped as follows takes no arguments:
int foo();
In fact, this function is deemed to take an unknown number of arguments. Using the keyword void within the brackets is the correct way to tell the compiler that the function takes NO arguments.
What's the deal with void main()
Under regular function calling/returning in C and C++, if your don't ever want to return anything from a function, you define it's return type as void. For example, a function that takes no arguments, and returns nothing can be prototyped as:
void foo(void);
A common misconception is that the same logic can be applied to main(). Well, it can't, main() is special, you should always follow the standard and define the return type as int. There are some exceptions where void main() is allowed, but these are on specialised systems only. If you're not sure if you're using one of these specialised systems or not, then the answer is simply no, you're not. If you were, you'd know it.
Be warned that if you post your "void main" code on the forums, you're going to get told to correct it. Responding with "my teacher said it's OK" is no defence; teachers have a bad habit of being wrong. Be safe, and post only standard code, and you'll find people concentrate on answering your other problems, rather than waste time telling you about this type of thing.
But what about int main(int argc, char *argv[], char *envp[])
As an extension to the guaranteed standard, an additional parameter to main() can, on some systems, be used to gain access to the environment variables. This is isn't guaranteed to work on all compilers, so use it with care if you want to keep your code portable.
===================================================================

DIFFERENCE BETWEEN MALLOC CALLOC

===============================================================
DIFFERENCE BETWEEN MALLOC CALLOC

Both malloc and calloc do the same thing with almost the same results, they allocate a block of n * sizeof ( T ) bytes of memory. The difference is in how the functions are called and how the memory block is initialized. malloc is called like so:
p = malloc ( n * sizeof ( T ) );
where the user programmer performs the operation to find the final block size. calloc takes two arguments and performs the operation itself:
p = calloc ( n, sizeof ( T ) );
malloc leaves the block of memory uninitialized, but calloc zero fills the memory. This does not mean that
p = calloc ( 1, sizeof ( int * ) );
will result in a pointer to int with a value of NULL. Zero filled memory does not mean that the memory is filled with the data type's equivalent of 0, so this zero fill cannot be relied on except with integral values such as int or char. Pointers and floating point may use a different representation for 0 than all bits zero.
Because of this zero fill, calloc can be slightly less efficient than malloc.

DIFFERENCES BETWEEN C and CPP

===================================================
DIFFERENCES BETWEEN C and CPP

Put simply, C++ is an extended C meant to improve safety, give the programmer more options, simplify higher level programming, and offer a better approach to large scale programming. C++ is also a larger language with more features and complexity than C, but C++ can improve productivity with its greater amount of features. A list of features that C++ supports which C does not includes:
Classes
Member functions
Constructors and destructors
Derived classes
Virtual functions
Abstract classes
Access control (public, private, protected)
friend functions
Pointers to members
static members
mutable members
Operator overloading
References
Templates
Inline functions
Default arguments
Function overloading
Namespaces
Exception handling
Run-time type identification
// comments
True const
Declarations as statements
Automatically typedef'd struct tags
Type safe linkage
new and delete
bool keyword
Safer and more robust casting
===============================================================

DIFFERENCES BETWEEN COUT,PRINTF

=================================================================
DIFFERENCES BETWEEN COUT,PRINTF

printf is a function that takes a variable number of arguments, the first argument being a format string explaining how to treat further arguments. cout is an object of the std::ostream class. The two are completely different in form, yet the result is the same, data sent to stdout.
This question is difficult to answer completely as often phrased since cout and printf are wildly different, but most often one of three questions are meant:
Q: "Which is faster?" A: printf, but the difference is too slight to worry about.
Q: "Which is better?" A: Neither, it depends heavily on personal preference and what needs to be done.
Q: "Which should I use?" A: You should use whichever you feel most comfortable with.It is preferred that you use iostreams with C++ instead of the C functions because iostreams are type safe and extensible for user defined types, both of which are very good reasons.
===================================================================

DIFFERENCES BETWEEN NULL AND 0, \0

==============================================================
DIFFERENCES BETWEEN NULL AND 0, \0

NULL is a macro defined in several standard headers, 0 is an integer constant, '\0' is a character constant, and nul is the name of the character constant. All of these are *not* interchangeable:
NULL is to be used for pointers only since it may be defined as ((void *)0), this would cause problems with anything but pointers.
0 can be used anywhere, it is the generic symbol for each type's zero value and the compiler will sort things out.
'\0' should be used only in a character context.
nul is not defined in C or C++, it shouldn't be used unless you define it yourself in a suitable manner, like:
#define nul '\0'
