As the technology evolves, so does the development of a driving power in business. In the earlier, businesses have been managed by individuals and procedures.These two factors  that drove the business overall performance and to ascertain no matter whether the organization would be successful in attaining its critical goals. So the have to have and great importance of programming was emerged.  

A programming language is a guy created language created to categorical the calculations can be done by a machine, which include a computer. Programming languages produces several plans that management the actions of a machine to categorical exactly in algorithms, or as an any form of human interaction assigned.

The principle of programming languages is a department of computer science specials with the design, implementation, assessment, characterization and classification of programming languages and their particular person attributes. The programming language is involved in the willpower of computer science, both in just and influencing arithmetic, software package engineering and linguistics. It is a properly-identified department of computer science, and an location of active investigation, with results printed in several publications focused to the PLT, and computer science in normal and specialized publications. Most undergraduate plans demand computer classes in the subject.

The role of language in programming has been demoted in favor of the methodology and software package applications, But it is wholly nullified if it is alleged that a properly created procedure can also be utilized in any language. But programming languages are not just a instrument, It also presents the uncooked product of software package, what we see on our screens day to day.

Programming languages exist only to fill the hole of abstraction between the components and the serious world. It is inescapable rigidity between abstraction larger, which is simpler to fully grasp and safer to use, and considerably less of abstraction, that are much more flexible and can typically be much more helpful. To design or find a programming language is to find an appropriate degree of abstraction, and it is not surprising that developer desire various ranges, or that one particular language may well be appropriate for a undertaking and not for an additional. In a unique language, a programmer must fully grasp in depth the implications of the protection and efficacy of just about every construction in language.

There are numerous programming languages like .Internet, Assembly, Fundamental, C, C#, C++, Delphi, Java, JavaScript, Pascal, Perl, PHP, Python, Ruby, VB-Script, Visual Fundamental and other languages and technologies. So Commence to find out programming and be a successful programmer.

In this article we will discuss how to change the contents of an HTML file by running a Perl script on it.

The file we are going to process is called file1.htm:

Note: To ensure that the code is displayed correctly, in the example code shown in this article, square brackets ‘[..]’ are used in HTML tags instead of angle brackets ”.

Imagine that we need to change both occurrences of [h1]heading[/h1] to [h1 class=”big”]heading[/h1]. Not a big change and something that could be easily done manually or by doing a simple search and replace. But we’re just getting started here.

To do this, we could use the following Perl script (script1.pl):

1 open (IN, “file1.htm”);
2 open (OUT, “>new_file1.htm”);
3 while ($line = [IN])
4 $line =~ s/[h1]/[h1 class=”big”]/;
5 (print OUT $line);
6
7 close (IN);
8 close (OUT);

Note: You don’t need to enter the line numbers. I’ve included them simply so that I can reference individual lines in the script.

Let’s look at each line of the script.

Line 1
In this line file1.htm is opened so that it can be processed by the script. In order to process the file, Perl uses something called a filehandle, which provides a kind of link between the script and the operating system, containing information about the file that is being processed. I’ve called this “opening” filehandle ‘IN’, but I could have used anything within reason. Filehandles are normally in capitals.

Line 2
This line creates a new file called ‘new_file1.htm’, which is written to by using another filehandle, OUT. The ‘>’ just before the filename indicates that the file will be written to.

Line 3
This line sets up a loop in which each line in file1.htm will be examined individually.

Line 4
This is the regular expression. It searches for one occurrence of [h1] on each line of file1.htm and, if it finds it, changes it to [h1 class=”big”].

Looking at Line 4 in more detail:

    • $line – This is a variable that contains a line of text. It gets modified if the substitution is successful.
    • =~ is called the comparison operator.
    • s is the substitution operator.
    • [h1] is what needs to be substituted (replaced).
    • [h1 class=”big”] is what [h1] has to be changed to.

Line 5
This line takes the contents of the $line variable and, via the OUT file handle, writes the line to new_file1.htm.

Line 6
This line closes the ‘while’ loop. The loop is repeated until all the lines in file1.htm have been examined.

Lines 7 and 8
These two lines close the two file …

Because the industrial revolution, culture has develop into a lot more and a lot more dependent on technology. So much so that we often absence the willingness to think ahead of we act. We develop into impatient if it will take a lot more than a couple seconds to down load a duplicate of the early morning news paper.

Like many web content authors, over the past few years I’ve had many occasions when I’ve needed to clean up a bunch of HTML files that have been generated by a word processor or publishing package. Initially, I used to clean up the files manually, opening each one in turn, and making the same set of updates to each one. This works fine when you only have a few files to fix, but when you have hundreds or even thousands to do, you can very quickly be looking at weeks or even months of work. A few years ago someone put me on to the idea of using Perl and regular expressions to perform this ‘cleaning up’ process.

Why write an article about Perl and regular expressions I hear you say. Well, that’s a good point. After all the web is full of tutorials on Perl and regular expressions. What I found though, was that when I was trying to find out how I could process HTML files, I found it difficult to find tutorials that met my criteria. I’m not saying they don’t exist, I just couldn’t find them. Sure, I could find tutorials that explained everything I needed to know about regular expressions, and I could find plenty of tutorials about how to program in Perl, and even how to use regular expressions within Perl scripts. What I couldn’t find though, was a tutorial that explained how to open one or more HTML or text files, make updates to those files using regular expressions, and then save and close the files.

The Goal

When converting documents into HTML the goal is always to achieve a seamless conversion from the source document (for example, a word processor document) to HTML. The last thing you need is for your content authors to be spending hours, or even days, fixing untidy HTML code after it has been converted.

Many applications offer excellent tools for converting documents to HTML and, in combination with a well designed cascading style sheet (CSS), can often produce perfect results. Sometimes though, there are little bits of HTML code that are a bit messy, normally caused by authors not applying paragraph tags or styles correctly in the source document.

Why Perl?

The reason why Perl is such a good language to use for this task is because it is excellent at processing text files, which let’s face it, is all HTML files are. Perl is also the de facto standard for the use of regular expressions, which you can use to search for, and replace/change, bits of text or code in a file.

What is Perl?

Perl (Practical Extraction and Report Language) is a general purpose programming language, which means it can be used to do anything that any other programming language can do. Having said that, Perl is very good at doing certain things, and not so good at others. Although you could do it, you wouldn’t normally develop a user interface in Perl as it …

Electronic Images has been around for a fantastic number of yrs now and the days of film cameras will have to definitely be numbered. Of study course there will often be individuals who do not want to embrace the ‘new’ issue, but for most ‘digital photography’ is the only way ahead. There is a continual advancing of technology in the digital camera industry and I have noted a number of of the newer concepts below.
Megapixel depend
Not much too prolonged back (a number of yrs) my 1.3mp digital camera seemed to do the trick and took some fantastic photos which I could print out on A4 paper. As time went by the sum of megapixels on cameras started off to increase and 5mp was thought of definitely fantastic. The camera I use now has 6mp and does a great task. Nevertheless, the megapixel depend utilized in dslr cameras continues to mature and the standard sum has now absent past 10mp to 12mp and some have 15mp or even 20mp !! When will it conclusion, or will it ??
It is explained that you must acquire a camera that has at minimum 6mp and I imagine that if you can afford one particular that has 10-12mp you have the ability to acquire definitely great images which can be enlarged very significantly with out any decline of excellent.
Camera shake reduction
This is a rather modern addition to digital cameras and performs definitely very well when you uncover that hand actions begin to lead to camera shake as you go to acquire a photo. There are 2 main procedures of providing the shake reduction. A single is to have the mechanism in the lens currently being utilized, and the other to have it in the camera entire body itself. If working with a camera entire body which has the shake reduction  integrated within then that usually means that it can be utilized with any lens while if working with stabilised lenses each lens utilized on the camera would require to have it. 
Sensor self-cleaning
The heart of the digital camera is the sensor and ultimately some dust will uncover its way onto it. There are lots of solutions specified for this for cameras which have no self cleaning mechanism.

Microscopic dust particles can get on your digital SLR sensor when you get rid of the camera lens. This dust shows up in every single image that you acquire. Self-cleaning sensors vibrate to avert and eliminate  digital SLR sensor dust. This self cleaning was extra a number of yrs back and does away with the require to get rid of lenses and get cleaning elements and so forth. to get rid of the dust which can be extremely uncomfortable for the aspiring photographer.
Reside Check out
This is where by you can get a watch of the supposed photograph on the substantial Lcd window on the back of the camera in contrast to currently being ready to glimpse by way of the …

Laptop computers are tiny individual computers created for applying on the shift. They commonly have all the features of a desktop computer but are transportable room-savers.

There are a lot of rewards to applying a lap leading computer – look at out just a few of them below.

A laptop computer computer is absolutely transportable

Portability is generally the most important advantage of picking out a laptop computer around a desktop computer. Portability implies that a laptop computer can be employed nearly anywhere, not only at dwelling and the office environment, but also during commuting, in lecture halls, coffee stores, libraries or in conference rooms to guide with shows.
