Top 10 Programming interview questions in 2020
An increasing number of students are opting for IT careers each year, since most of…
Gone are the days when you had to be an uber geek to know how, or indeed feel the need, to write a computer program. Many experienced and senior programmers today learnt to code the hard way during the advent and popularization of personal computers in the 80s and 90s, but the game has very much changed since then.
In this modern era, our lives are pretty much governed by the presence of computers; from the smartphone in your pocket to the television you watch tv shows on, and even the microwave oven that prepares your popcorn for you as you binge watch your favorite shows – there’s a type of computer everywhere, and as such it can (often) be programmed.
So why should you learn to program when your Google Assistant (or Siri) can maintain your calendar and Alexa can order your food for you? The simple answer; demand. Computer programs are replacing humans, and the demand is now for people who can write a program to do a certain task, rather than doing that task themselves. According to an estimate by the US Bureau of Labor Statistics, software developer jobs will continue to grow at a rate of 22% from 2012-2022, growing almost three times faster than any other industry.
For people unfamiliar with programming languages, starting out can be really daunting. There are so many fields within programming, so many avenues you can explore that it is very easy to get caught up in a web and lose track of the original purpose.
At the lowest level are assembly languages, which are specific to each system type. Your personal computer typically runs on Intel x86 (or a similar architecture), whereas your smartphones are generally ARM-based. Assembly languages were popular back when personal computers were first invented, but these days higher-level language compilers have taken over that job. Beginners no longer need to learn assembly in order to program a computer.
While C is taught for basic to advanced programming concepts, it is entirely possible for beginners to skip it altogether and start off with a more modern language.
To really understand how learning a programming language can help, it is important to get some context with respect to how each system around us is programmed. Apps that you use on your smartphone are largely developed using Java (for Android) or Objective-C (for iOS). Desktop software is typically written in C/C++ (including Windows, Linux and macOS operating systems themselves) or C# (in case of Windows applications).
On the web backend, the most popular languages used are PHP, Python, C# or Java. These languages are common across various platforms, and are essential to learn for any beginner.
