In our age of technology, where we are becoming more and more reliant upon programming, being able to programme makes you incredibly employable. Programming is one of the most sought after skills to have in the tech world and financial, media and design companies all rely upon programmers and their coding skills. Indeed, this extends beyond these sectors, and some of the advantages of being a programmer include competitive salaries, flexibility as long as you complete your projects on time, and job security as a result of the great demand in this area. Regarding training, the entry requirements for computer programming courses are low, and individuals who are self-motivated and have an interest in this area can learn by themselves.
A computer programmer or systems developer is a person who essentially writes codes and creates programs for computers and operating systems using of the several specific coding languages to do so. The most basic definition of computer programming is a process by which you solve a problem. However, the languages you use to do this are specific to this form of problem-solving. Here are some of the most popular programming languages and a rundown of what they are used for.

The original coding language, invented in the early 70’s by Denis M. Ritchie is a general purpose language that is widely used. C language provides the foundation for many other languages and built upon by C++ and C# in particular. This is used for embedded applications and implementing operating systems.
This programming language is the primary programming language used to power Apple’s operating system and is popularly used to create iPhone apps. This adds Smalltalk-style messaging to the C programming language and is an object-oriented language which means it is one that is built around the concept of objects, interacting with the physical through code. Objective-C is a great first language to learn if you are particularly interested in iOS development.
Java is one of the most popular programming languages, developed by Sun Microsystems in the 90’s and is used for enterprise software, web-based content, the Android operating system and games and mobile apps. This is an object-oriented language that is similar to C++ but simplified to eliminate language features that could cause programming errors. Java has more than 9 million java developers worldwide, indicating its popularity. Some of the most common difficulties programmers come across when using Java include compiler errors, Java exception handling and the “unclosed string literal error”.

PHP, also known as Hypertext Pre-processor is a scripting language which is the one the most popular and easiest to use. This is used to enhance web pages and allows you to create usernames and login pages, create forums, pages and surveys to name just a few of the features. This language enhances or ‘livens up’ standard HTML and is a must for people wanting to get into the web design industry.
Like PHP, Python is a server-side scripting language for websites and mobile apps. The benefit of Python is that it is easy to learn and fewer lines of code are needed than other languages. Python powers well-known apps such as Instagram and Pinterest.
Ruby runs on conventional, file-based source code which follows the “Principle of Least Surprise” More than a scripting language, Ruby is a general purpose programming language and can be used to manage server machines and databases, write GUI’s or even machine learning programs.
If you are looking for a career change, embarking on your career, or simply looking to add a tool to your belt, you can be secure in the knowledge that the reliance upon programming will only increase in the future and therefore this is an important and useful skill to have.
