Pearl is an acronym for practical extraction and report language. Pearl is a simple programming language that was developed by Larry wall and can run on several platforms such as Windows, Mac OS, and UNIX. It was first intended for text processing and manipulation; however, over the years it has evolved and is used generally as a programming language that is used in developing websites, network programming and so forth.
When the pearl is used on sites, we then refer to it as peal CGI. It is through the common gateway interface (CGI) that pearl programming can communicate with your browser and give commands. For instance, pearl programming in most cases responsible for rotating banners, setting cookies, providing shopping carts, generating text and HTML.
Regardless of whether you are new to programming, or have used other programming languages such as C++ and Java, learning pearl is a simple, exciting and rewarding experience.
This article will show you how to learn pearl programming to make a website.
The best way to learn pearl programming is through real hands-on coding. There are numerous books and tutorials online on how to code using pearl programming language, but you should use them as reference tools while practicing.
Make good of CPAN as it is known to have pearl codes that are useful and relevant and you can apply them to a situation that only you is facing. You will have a better advantage if you know other programming languages such as Python, PHP and C- based languages as this will enhance your creativity level.
First, make that you download and install pearl on your computer. Then install CPAN minus modules, which will make your coding work easier. You do not have to re-write codes for a similar operation. These module codes allow you to do tasks that for certain operations.
We also need to know about variables as they will help you learn how to use pearl better.
There are three important types of pearl variables that are a must learn, they include scalar, arrays, and hashes.
This variable holds a single value. Declared by a dollar sign then the name of the scalar.
It is the type of variable that stores data in list form. There is the use of unique index numbers that allow you to access specific elements. It very simple to create an array, you define it using “@” then followed by your preferred name of the array. The array is used to store numbers, floating values and strings.
It has a similar capacity to hold as many scalars as an array. It is declared by starting with a % followed by your preferred name of the hash.
In conclusion, using pearl programming language is all about being creative. If you are creative enough, you can scope and utilize the numerous advantages associated with using pearl programming language regardless of whether you are a web developer, a hacker or just a mere nobody. You will always find a better way to re-write your codes.
