The economic crisis may have affected wages and the type of employment contract, but certainly a good programmer will never be unemployed, especially if he has studied the right languages for modern IT activities . The demand for IT programmers has been growing for several years, for some more than others, depending on which and how many codes they know.
Planning is, theoretically, a job that everyone can do that can be learned at any age, even as a child.
Both for those who would like to start programming as a hobby, and for those who are determined to study to become a programmer or professional developer, let's see which programming languages are most used and, therefore, most requested by the job market (it is not a ranking).
For each of these languages, we also leave a link to find a tutorial or guide to learn more and, if desired, also to learn independently by studying alone.
1) Java
Java is always one of the most popular languages for application development, in particular for developing apps for Android or for new smart devices (Smart TV, Smart Auto etc.).
With Java and frameworks based on this language, developers can create scalable web applications for a wide variety of users.
If we try to search for any ad for programmers, this language is omnipresent so better to learn it right away.
For a guide to the Java language, we can go to the HTML.it website
2) C
The C language is still quite popular because it allows you to develop small, light and fast software.
Once you learn its mechanisms, it becomes very easy to switch from one language to another (especially with the more modern ones).
Among the oldest, but still in great demand due to its versatility.
A complete C guide can be downloaded from the Maffucci.it website
3) Python
Those who know how to work with Python can do almost everything: web applications, user interfaces, data analysis, statistics and much more.
Python is also used as a research tool to process huge databases in any sector.
If we have never heard of it before, better update and study this language, so as to be ready to respond to the ads that require it (more and more).
The Pyton.it site is great to start with.
4) C ++
If you prefer a programming language that allows you to connect the hardware to the software to get the most out of the processing power then you can study C ++, an ideal choice for the development of powerful desktop software, games with hardware acceleration and high intensity applications memory for PC, console and mobile devices.
Mentr those who know Java should not have difficulty learning C ++, we can safely say that starting from C ++, you can learn practically any other programming language, weather permitting.
In addition to HTML.it, good is the Italian guide to C ++ of sitoserio.it
5) SQL
Without a shadow of a doubt one of the most requested languages can only be the one for the creation of databases, in particular for MySQL databases. SQL is not a programming language, but a relational database query language, at the basis of all the work that has to do with databases, including websites.
To learn SQL we can start on HTML.it
6) JavaScript
If you know Java, it is also easy to write JavaScript codes for websites, in order to make them more dynamic and interactive with various types of automatisms (such as adapting to the user's screen, performing targeted searches, resizing images etc.).
Knowing the programming in Javascript it becomes quite natural to use both Ajax (Asynchronous JavaScript and XML) and jQuery scripts.
Even for a preliminary guide to Javascript, HTML.it seems updated and competent.
7) C #
C # is the main language for developing Microsoft platforms and services and modern web applications Azure and .NET.
Learning C # is therefore the fastest way to create programs optimized for Windows and take advantage of all that the Microsoft platform offers.
Additionally, for video game enthusiasts, C # is the language of the popular Unity online game development engine.
For a guide to C # we can go to the Microsoft site.
8) Ruby
The Ruby language, simple to learn and incredibly powerful, powers many of the most popular web applications around the world.
Increasingly in demand in the field of Web applications, it is better to learn it so as to be ready for any request from the employer.
The most complete guide in Italian to learn how to program in Ruby is surely that of the Ciaburro website
9) Objective-C
Objective-C allows you to create applications for the iOS world, then for iPhone or iPad.
Knowing how to program with Objective-C and XCode, Apple's official software development tool, there will really be no technical barriers in publishing an app on the iTunes store, just create your own app and publish it (both for free and with various forms of payment), from in-app purchases to the subscription).
If we know the C language, it becomes easy to approach and understand Objective-C.
HTML.it offers a free preliminary guide to Objective-C in Italian.
10) Swift
The Swift programming language (from Apple) is among the most recent but it is already considered as one of the languages to be known by force, because it allows you to develop applications for Mac and iPhone, that is, some of the most used platforms in business.
Swift's power and friendly syntax make it possible for anyone with a Mac to create the next successful application for iOS or Mac OS X.
While on HTML.it we can find an initial guide in Italian, to get a complete overview of the Swift language you must visit the Swift.org website
11) Perl
Perl is a very powerful language and a key component for those who want to work in the security sector.
Perl is still considered a fundamental tool for all IT professionals.
Knowing how to use Perl scripts, learning Python, which is easier, should also be a walk.
Guide to Perl once again on HTML.it
12) Visual Basic
Visual Basic is a fundamental language of the .NET platform, to create business applications and automate programs such as Excel to carry out very complex operations and to lighten the most common and repeated activities.
More than as a request in itself, learning to program in Visual Basic will save a lot of time during our work.
On the Microsoft website, the guide to Visual Basic in Italian
13) PHP
Those who intend to work on websites will have to learn PHP, the language with which most websites are developed. PHP and MySQL databases are essential tools for building modern web applications, to the point that they are requested together in a job offer.
Since studying PHP is not so difficult, it can be useful not only for working, but also for creating your own website or blog with platforms such as Wordpress, which can also be used without knowing codes, but which allows those who develop in PHP to make the site significantly more powerful and beautiful to look at.
Of course, by studying PHP you also quickly learn to write HTML web pages and to use CSS style sheets.
If we dream of creating our site from scratch or we want to create sites for companies, PHP is the programming language that we must learn.
To start with PHP, good is the guide in Italian on the Ionos.it website
