Programming languages today

Programming languages have never been as widely used as they are today. Jesús Lagares Galá, student of Computer Engineering at the University of Cadiz and collaborating student at the Department of Computer Engineering, is aware of this and has given us an interesting lecture on Programming languages for cybersecurity at C1b3rWall Academy 2021.

The aim of his talk has been to highlight the importance of programming languages today, to give a brief introduction to anyone who does not know what they are and how they work, and to encourage the listener/reader to delve into this world.

The pandemic has accelerated the technological boom around the world, so learning and using programming languages is becoming less of an option.

What is a programming language?

A language is a set of signs and rules agreed upon by humans to convey a message. The programming language represents the set of instructions that allow the computer to perform certain functions, a language that we use to communicate with our computer. Just as in any language we have a grammar or syntax, the same thing happens in programming, with different elements that compose it: variables, type semantics, conditional structures, etc. Some examples of programming languages are C, Java or PHP. There are also languages that do not have these elements and therefore are not entirely considered programming languages, such as HTML.

Which language should I start with?

Python or PHP are easy options to start with. However, the choice depends on one’s goals. Would you like to earn a lot of money and not invest too much time? Learn Perl, Scala, Rust, Go or Ruby. Would you like to program web pages because you are passionate about it? Use PHP or JavaScript.

There is no doubt that knowledge of programming languages is a highly demanded skill and employers will increasingly search for employees with those skills.  Therefore, I invite you to learn more about this interesting world in Module 4 of C1b3rWall Academy.
