Computers now run and control almost every part of society, with more and more high-tech devices appearing. The software makes all of these different kinds of technology work together. It runs the world, and programmers are fully responsible for how it works. Since there is a huge need for computer programmers, it shouldn’t be a surprise that they get paid a lot. But what does a computer programmer do, exactly?

This article will answer that question. We will also talk about possible jobs, how much they pay, related programming languages, and why a degree in computer science might be a good first step.

What Is Computer Programming?

Computer programmers, in the most basic sense, are the people who are in charge of writing computer programs. These programs let other people use a computer to do certain tasks. Programmers can also write code and programs to make computers work better and more efficiently.

Programming in computers is an important part of today’s technology. This is because it lets everyone, from coders to CEOs, get the software they need to do their jobs better. Computers have a big effect on our lives in many ways, from sending emails to coworkers to using spreadsheets to keep track of our money. Computer programmers come in at this point.

What is computer programming?

As more people use digital devices to check the weather, do the math, play video games, and “like” their friends’ posts, the need for people who can write computer code has skyrocketed. According to a 2019 study by the Pew Research Center, 81% of Americans own a smartphone and 96% of Americans have a cellphone. According to the group, this number was only 35% lower than it was when Pew Research did its first study on smartphone ownership ten years earlier. Based on the results of the study, more than 75% of Americans own a desktop or laptop computer, and about half also have an electronic reader and a tablet computer.

Programming skills are needed for a wide range of technical jobs. In addition, they are especially helpful for jobs that involve developing software or the web. The US Bureau of Labor Statistics (BLS) says that between 2021 and 2031, the number of jobs in web development could grow by up to 30%, which would add 28,900 jobs.

What Does A Computer Programmer Do?

Computer programmers should try to figure out what their customers want. The software is then planned, built, and tested to make sure it meets the requirements laid out. Computer programmers will also use their skills to make sure that the software meets industry standards and best practices for performance, dependability, and security. 

They also work with other designers and programmers to plan each part of an application or piece of software. This will happen before figuring out how those parts will work together. Computer programmers are usually in charge of writing computer code in languages like Python, C++, and Java that computers can understand. Afterward, they will test it to make sure it works correctly. They will use debugging to fix any mistakes or problems that may have happened with the app. Maintaining, changing, or fixing already-made programs, as well as writing user guides are also parts of their responsibilities.

We will delve into it more specifically.


Making code for new computer programs and testing it

When writing code for new mobile apps or computer programs, computer programmers work closely with web developers and software engineers. In some situations, programmers may build the look, feel, and functionality of a new software application. Most of the time, making new code requires a lot of trial and error. Computer programmers are good at analyzing and solving problems. They also enjoy using logic to figure out how to solve difficult problems.

Adding new features to the software that is already in use

Also, programmers are in charge of making new versions of software that have already been released and installing them. Fixing bugs and adding new features are two examples of how an update could make the user experience better. Depending on how complicated the project is, it could take anywhere from a few days to several months to finish.

The process of finding and fixing mistakes in the code

As part of their regular jobs, computer programmers may help figure out errors of a website or computer program. Most problems result from mistakes in the code, and a programmer can help find and fix the mistake quickly.

Applying changes to make it work with a wide range of operating systems

Programmers often have to rewrite code in a lot of different languages so that it works with a wide range of operating systems. This is necessary so that software can run on more than one platform. For example, apps for Windows are written differently than apps for OS X. Some programmers are taught how to make new apps with code that works on both operating systems, so they can run on either.

Protect computer programs from threats that come from the internet

A large number of computer programmers work in the field of cybersecurity. These programmers help find malicious software and fix software that could be broken into. Also, programmers can write code that keeps data from getting out or security from being broken. The number and severity of cyberattacks are likely to make more people want to learn about information security. The Bureau of Labor Statistics (BLS) says that between 2017 and 2031, the number of jobs for information security analysts is expected to grow by 35%, creating 56,500 new positions.

Web Developer

Computer programmers can use their coding skills in many different ways, such as making games and websites. Web developers are in charge of how websites look and how they work for people who visit them. This means keeping up with the design and technical aspects of the website, such as its speed and ability to handle a certain amount of traffic.

Markup languages like HTML, CSS, and JavaScript are used by front-end developers to bring a website to life. Back-end developers care less about designing the user experience and more about making sure that all the parts work together as a whole. Most of the time, PHP, Ruby, or Python are the best languages to use when making apps that link a website’s back end to its front end.

Computer programmers usually work for companies with IT departments. They may also be able to work from home or as freelancers. Programmers work in many different fields, such as healthcare, finance, government, defense, retail, science, education, business, and entertainment.

Video Game Developer

Developers of video games make games on different platforms, such as the web, mobile phones, and desktop computers. A single video game can have tens of gigabytes of data, millions of lines of code, and very complicated logic. Animating 2D and 3D characters, building character models, and coding game logic are the main things that video game producers do.

Database Administrator

Database administrators are in charge of making, managing, and keeping an eye on the databases used by their organization. They must be good at computer programming and know a lot about operating systems in order to make software that meets the needs of users and works well with network activities.

As part of a team, they usually work with other database experts who are experts in different areas or projects. Database administrators talk directly with senior management on a regular basis to make sure that the company’s technology works well.

In the data field, we also have a couple more roles which you can consider.

Data Analyst

The job of data analysts is to make sense of the huge amounts of data that businesses produce. They use programming languages like Python and R to look for patterns and trends that could be important for the future of the company. Then, they put together reports for internal use or for clients that explain these patterns and trends in a way that decision-makers can understand. This could include making graphs, charts, and other ways of showing data.

Data Scientist

Both a data analyst and a data scientist work with information that comes from different places. On the other hand, a data scientist uses machine learning to look at company data in order to find useful insights. In the last few years, machine learning has made more progress than ever before. Data scientists are in charge of making machine learning models that can make predictions based on past data to help companies make better decisions.
