1. Estimates (i.e. budget, schedule, etc.) become more realistic as work progresses, because important issues are discovered earlier.

2. It is more able to cope with the (nearly inevitable) changes that software development generally entails.

3. Software engineers (who can get restless with protracted design processes) can get their hands in and start working on a project earlier.

Differences between .Net and Java include

• Java is from Sun, .Net is from Microsoft
• Java is a language plus a runtime, .Net is a runtime framework that supports multiple languages, Visual Basic and C# (the .Net language most similar to Java) among them.
• C# is very similar to Java but a few years younger, and a bit nicer in some respects - it has a slightly simpler syntax for some common constructs.
• Java is more platform independent, it runs on several operating systems including Windows, Mac and Linux. .Net is primarily for Windows. Although the open source project Mono is developing a multi-platform runtime for .Net, so this is less of an issue than it used to be.
• .Net has a more integrated development environment, as the IDE, runtime and server all come from Microsoft as a standard package, while Java is based on third-party tool and server providers. It used to be the case that the .Net development environment was clearly superior, but the difference is smaller these days.
• It can be argued that Java gives more flexibility, as there are more server- and IDE-providers to choose from, at the cost of some extra overhead for the developer to get the different pieces to work together.

Functionality wise, there is not a lot of difference between the two, at least not when used to develop web applications.

For desktop applications, .Net naturally has an edge in Windows integration.

note: Oracle bought Sun Microsystems (Sun).

Assembly language is used to write programs using the instruction set for a particular processor/controller.(example : 8051 or 8086 or MIPS).

• It is confined to a particular machine, it involves symbolic representation of the binary machine codes and other constants needed to program a given CPU architecture.

Assembly Language require an ASSEMBLER to convert the assembly code to machine level code(HEX CODE)

High Level Language require a Compiler to convert into ASSEMBLY THEN machine level code.(Now-a-days compilers are smart enough to generate the machine code directly)

To write assembly code it is necessary to know the architecture of the processor or controller.

To write an High Level Program it is not neccessay to know the architecture completly.

Assembly language is not protable.

High Level Language is Portable.

A programming language that is once removed from a computer's machine language. Machine languages consist entirely of numbers and are almost impossible for humans to read and write. Assembly languages have the same structure and set of commands as machine languages, but they enable a programmer to use names instead of numbers.

Each type of CPU has its own machine language and assembly language, so an assembly language program written for one type of CPU won't run on another. In the early days of programming, all programs were written in assembly language. Now, most programs are written in a high-level language such as FORTRAN or C. Programmers still use assembly language when speed is essential or when they need to perform an operation that isn't possible in a high-level language.

High-level language:-

• A high level language hides the micro abstractions such as set of command required to be performed by the processors such as CPU. Java and C++ are all high level languages.
• Java, C++ : all easy to write non-binary languages
• Example : (i=10, i<10,i++)
• It is not confined to particular machine.

-JP Morgan

A programming language such as C, FORTRAN, or Pascal that enables a programmer to write programs that are more or less independent of a particular type of computer. Such languages are considered high-level because they are closer to human languages and further from machine languages. In contrast, assembly languages are considered low-level because they are very close to machine languages.

The main advantage of high-level languages over low-level languages is that they are easier to read, write, and maintain. Ultimately, programs written in a high-level language must be translated into machine language by a compiler or interpreter.

The first high-level programming languages were designed in the 1950s. Now there are dozens of different languages, including Ada, Algol, BASIC, COBOL, C, C++, FORTRAN, LISP, Pascal, and Prolog.

An assembly language is where each statement corresponds to one machine instruction. A high level language is where each statement corresponds to more than one, sometimes many, machine instructions.

switch is a loop which is used for checking various conditions and print corresponding matter.

switch(a)//where a is that whose condition you have to check.

#include

main()

{

char a;

printf("enter a char.");

scanf("%c",&a);

switch(a)

{

case 'a':printf("vowel");break;

case 'e':printf("vowel");break;

case 'i':printf("vowel");break;

case 'o':printf("vowel");break;

case 'u':printf("vowel");break;

default:printf("consonent");

}

}

the features of oop are:

1. Emphasis is on data rather than procedure.
2. Programs are divided into what are known as objects.
3. Data structures are designed such that they characterize the objects.

4. Functions that operate on the data of an object are tied together in the data structure.

5. Data is Hidden and cannot be accessed by external functions.

6. Objects may communicate with each other through functions.
7. New data and functions can be easily added whenever necessary.
8. Follows bottom-up approach in program design.

· Robust

· Multi threaded

· Architecture Neutral

· High Performance

· Distributed

· Dynamic

Swapping two values in a single statement is made possible through a series of three XOR/assign operations, alternating the operands.

Consider the following declarations:

int x = 0;

int y = 1;

The following statement will swap the values of x and y:

x ^= y ^= x ^= y; // swap

The same statement implemented as a function:

void swap(int &x, int &y){ x ^= y ^= x ^= y; }

Go to your button and double click it to go to the code then add this

Dim NameOfFile as String

NameOfFile = InputBox("Enter the Name of The File", "")

Dim objWriter As New System.IO.StreamWriter("C:/" & NameOfFile.ToString & ".txt")

Msgbox("COMPLEATE")

You can display a textbox value in another form using Vb.NET. Simply by inputing this line of code:

'You can put this code anywhere under a Private Sub or Sub'

'I Will use an example of a textbox named "testabc" and "othertextacbc

TestAbc.Text = frmMain.OtherTextAbc.Text

'You can replace the "frmMain with the form you are trying to access.
