Language Programming

Salam Semua (Hye to All)!!

Ok..merujuk kepada post dari ahli kumpulan saya iaitu Intan Naquiah, saya ada sedikit tambahan mengenai tajuk yang dibincangkan sebelum ini..Ini adalah dari pemahaman saya mengenai ASP.Net (Active Server Pages) dan PHP (Hypertext Preprocessor) disamping tunjuk ajar dari rakan sebilik saya, NOOR SHYAHIRA BINTI ADNAN..:)

ASP.NET (Active Server Pages)

Asp.Net digunakan untuk membuat sistem dan laman web dan bahasa program ini boleh meggunakan C# atau dipanggil "C Sharp" dan VB.Net. Kebanyakkan programmer menggunakan bahasa ini sebab ia mudah digunakan kerana kebanyakkan item-item di dalam bahasa tersebut tersedia ada. Cuma perlu "drag and drop" sahaja tetapi programmer mestilah tahu mengenai kod di belakang barulah "function" dapat berjalan dengan baik. Pangkalan data untuk Asp.Net sudah sedia ada dan programmer hanya perlu "drag and drop" sahaja. Keseluruhannya, Asp.Net senang dan memberikan kemudahan kepada programmer untuk membuat sistem atau laman web.

PHP (Hypertext Preprocessor)



PHP merupakan salah satu bahasa pengaturcaraan (language programming) yang diguna pakai sejak dulu sampai sekarang. PHP sangta stabil untuk membina sistem, software dan laman web. PHP akan digabungkan dengan menggunakan database yang dipanggil "phpmyadmin" untuk membuat sistem dan laman web dan software. Programmer perlu 'install' XAMPP server di laptop dan 'setting ' terlebih dahulu.

Contoh simple coding:


Zhtml>
Zbody>


echo "Hello Dhiaa";
?>




Output yang akan terpapar kepada user adalah "Hello Dhiaa"

Antara Asp.Net & PHP, PHP perlukan seseorang itu membuat kod yang penuh dengan sendiri. Programmer itu akan menggunalan notepad sahaja untuk membuat kod. Notepad itu mestilah disimpan seperti:

• Sebagai contoh "hello.php". Tambahan di belakang itu perlu diletakkankt dot (___.php)

Cara menyimpan file coding seperti:

• "hello.php" .Letakkan double quote " " untuk elakkan file tersebut disimpan sebagai .txt tetapi kita tidak mahukan .txt..hanya .php sahaja
  

Language Programmer yang menjadi pasaran sekarang adalah:

1) Java (JSP@ J2EE)
2) PHP
3) Asp.net
4) Android (language progamiing dlm mobile phone)

Sekadar itu sahaja megenai pemahaman saya tentang Asp.Net dan PHP..jika ada tambahan lagi, di alu-alukan dalam memberikan idea anda...sharing is caring..:)


See you Next Time!!

5 Programming Language You Should Learn Right Now!

Among thousands, 5 programming languages stand out for their job marketability and wide use. If you're looking to boost your career or learn something new, start here.

Knowing a handful of programming languages is seen by many as a harbor in a job market storm, solid skills that will be marketable as long as the languages are.

Yet, there is beauty in numbers. While there may be developers who have had riches heaped on them by knowing the right programming language at the right time in the right place, most longtime coders will tell you that periodically learning a new language is an essential part of being a good and successful Web developer.

By picking the brains of Web developers and IT recruiters, eWEEK selected 5 programming languages that are a bonus for developers to add to their resumes. Even better, they're great jumping-off points, with loads of job opportunities for younger recruits.

Java is one of the most popular programming language

1. PHP

What it is: An open-source, interpretive, server-side, cross-platform, HTML scripting language, especially well-suited for Web development as it can be embedded into HTML pages.

Why you should learn it: Its particularly widely used. "High-speed scripting with caching, augmented with compiled code plug-ins (such as can be done with Perl and PHP) is where the future is. Building Web apps from scratch using C or COBOL is going the way of the dinosaur," said Duquaine.

Job availabilities: 1,152*

2. C#

What it is: A general-purpose, compiled, object-oriented programming language developed by Microsoft as part of its .NET initiative, it evolved from C and C++

Why you should learn it: Its an essential part of the .Net framework. "Learning C#, which is just Java with a different name plate, is critical if you heavily use Microsoft," said Duquaine.

Job availabilities: 5,111

3. AJAX (Asynchronous JavaScript and XML)

What it is: Though technically not a programming language, AJAX uses XHTML or HTML, JavaScript and XML to create interactive Web applications.

Why you should learn it: Ever since Google Maps put AJAX, well, on the map, the requests for AJAX-knowledgeable pros went through the roof. "The demand for AJAX knowledge is huge because its so damned hard to learn," said Huckaby. Of note, Microsoft announced recently plans to release a tool named Atlas that will make AJAX easier to implement. "If Microsofts Atlas tool is successful, it would bring the extreme complexity and annoyance of AJAX to the average worker," said Huckaby.

Job availabilities : 1,106

4. JavaScript

What it is: Not to be confused with Java, JavaScript is a an object-oriented, scripting programming language that runs in the Web browser on the client side. Its smaller than Java, with a simplified set of commands, easier to code and doesnt have to be compiled.

Why you should learn it: Embedded into HTML, its used in millions of Web pages to validate forms, create cookies, detect browsers and improve the design. With its simplicity to learn as well as wide use, its considered a great bang for your educational buck.

Job availabilities: 4,406

5. Perl

What it is: Perl is an open-source, cross-platform, server-side interpretive programming language used extensively to process text through CGI programs.

Why you should learn it: Perls power in processing of piles of text has made it very popular and widely used to write Web server programs for a range of tasks. "Learning some form of scripting language, such as Perl or PHP is critical if you are doing Web apps," said Duquaine.

Job availabilities: 4,810

Most Popular?

As, conclusion,There are a number of ways to measure the popularity of a programming language, for example, based on the number of:

• New applications written in the language
• Existing applications written in the language
• Developers that use the language primarily
• Developers that use the language ever
• Web searches
• Available jobs that require skills in the language
• Developers’ favorites

Repetition Structure

What are the Difference Between these TWO Repetition Structure? 

Last week, Madam Sharin Hazlin had told us to post new entry about what are the difference between these two repetition structure

DO......... UNTIL  AND DO.......WHILE?

Repetition Structure : When we talk about allows a user to specify that a program should repeat an action while some condition remains true. 

DO..... UNTIL (DOU)

The DOU operations allow the processing of a group of calculations one or more times. The end of a Do-Until operation is indicated by an ENDDO operation. Here processing is done at least one time.

DO...... WHILE (DOW)

The DOW operations allow the processing of a group of calculations zero or more times. The end of a Do-While operation is indicated by an ENDDO operation.

The do-while is very similar to the regular while with just one difference. The while is a leading decision loop, but the do-while is a trailing decision loop. Therefore the condition is at the beginning of the while loop but at the end of the do-while loop. For that reason a while may be executed zero times, such as when the condition is initially false. On the other hand, the do-while is always executed at least once, because the condition is not even checked until after the first execution of the loop body.

This flowchart illustrates the general logic of a trailing-decision loop. The body of the loop is executed at least once, because the condition test follows the body. A trailing-decision loop can also be implemented using a while loop, which is illustrated in the next exhibit. 

Do...While Example

Suppose you want to verify that the user input was a positive number, and if they enter a negative or zero to keep prompting for correct input. Clearly, in this case you need to get the input before you test for the condition, therefore we need a do-while loop:


int age;
do{
String input = JOptionPane.showInputDialog("Please enter a value for age");
age = Integer.parseInt(input);
}while(age<=0); 

The general for of the do-while statement is:do
statement 
while(condition);

What is computer language? Explain the different types of computer language?

Group K-Learn4U computer language like human talk to chicken....means we cannot understand each other....only them can understand each other.

In my understanding from the group presentation, they said computer language have fifth generation language. Their group also show the class example of computer language and the are talking about real things when said human never understand what chicken is talking. Computer language just represents number and the number represents information! So amazing! The lower programming language is better for focus on curtain task..

The term computer language includes a wide variety of languages used to communicate with computers. It is broader than the more commonly-used termprogramming language. Programming languages are a subset of computer languages. For example, HTML is a markup language and a computer language, but it is not traditionally considered a programming language. Machine code is a computer language. It can technically be used for programming, and has been (e.g. the original bootstrapper for Altair BASIC), though most would not consider it a programming language.

Computer languages can be divided into two groups: high-level languages and low-level languages. High-level languages are designed to be easier to use, more abstract, and more portable than low-level languages. Syntactically correct programs in some languages are then compiled to low-level language and executed by the computer. Most modern software is written in a high-level language, compiled into object code, and then translated into machine instructions.

Computer languages could also be grouped based on other criteria. Another distinction could be made between human-readable and non-human-readable languages. Human-readable languages are designed to be used directly by humans to communicate with the computer. Non-human-readable languages, though they can often be partially understandable, are designed to be more compact and easily processed, sacrificing readability to meet these ends.

Online Calculators Answer Life's Questions
Programming language can benefit to human life when it transfer into calculator applications. For example, one program can help parents to expect when their child will be born and even some to generate baby names. Once the child is born, they can use another calculator that attempt to estimate the total cost of raising the child throughout the teenagers years.
There are certain web site been provide this kind of services, for example Your Life Calculators. This MSN-sponsored site organize the calculators in a variety of categories. The career section include a millionaire calculator to determine how much money will need to be saved each month to reach $1 million, and what interesting is it also includes amortization tables and mortgage and car loan calculators.
Moreover, other tools are the tip calculator, a calculator that determines the chances of a successful personal relationship, the body mass index to measure body fat based on height and weight, the college cost calculator, and the financial aid calculator.


Comment: When using online calculators, keep in mind that some are subjective in nature, and the results reflect the thoughts or opinion of the calculator's author.
