In the 21st century, we have seen an accelerating speed in technological advances. Everywhere we look, everything we use—all these has something to do with technological developments. From cellphones to alarm clocks in the morning, to coffee machines that prepare us coffee with just a single push button, and of course to smart devices that help us live an easier life—all these things take advantage of technology. But behind all the things we see online—every chart, every word, every picture—there’s a man that’s behind it to make these things so easy for us: the computer programmers.

Frequently Asked Questions

What is Computer Programming?

Ever wondered how computers, software programs, or applications perform? Thru coding, of course. And how do these codes work? By computer programming used by professionals to write these codes. In its simplest form, computer programming is a set of instructions to perform specific actions. So, what do computer programmers do? They create specific instructions for the computer to execute by making and testing codes that allow software programs and applications to operate successfully. 

Computers can perform so many things. A simple laptop can make a basic spreadsheet or word processing function. Supercomputers can create a massive infrastructure that can make modern life possible. But all these are useless until a computer programmer gets into the picture and ‘tells’ these computers to behave in a specific way. This is what computer programming is about.

Programming is nothing more than a set of instructions created to enable specific actions. Although this depends on the purpose or requirement, computer programming can be as basic as adding numbers or as complicated as reading data to obtain critical reports, sort out data, or adjust a thermostat sensor. 

What Can You Do as a Computer Programmer?

As a computer programmer, you make instructions that you want the computer to execute. You write and test a code that makes a software program and application run smoothly. As a whole, computer programmers use specific languages to communicate with applications, computers, and other systems so that computers and networks can successfully operate a set of tasks. According to ComputerScience.org, most computer programmers use computer languages like Python, Java, and C++. This allows the programmers and the software engineers and developers to build programs that “surf, search, and selfies.” 

Free Online Classes_Programming - fact 2

Today, there are different types of programming languages. However, below are the top 10 programming languages commonly used, based on a 2018 survey of 100,000 programmers. These languages include:

  • JavaScript
  • Java
  • SQL
  • Python
  • PHP
  • C#
  • C
  • C++
  • Ruby
  • Typescript 

O*Net online said the most common tasks every computer programmer must master should include:

  • Finding solutions to problems in computer software
  • Testing the performance of a software
  • Altering software programs to enhance their performance
  • Writing programming codes
  • Working with others to resolve technology issues

How Can You Become a Successful Computer Programmer?

Here’s a fun fact: there are so many programmers out there who started as self-taught enthusiasts. One prominent self-taught gamer, Dr. Ed Laviera, started as a self-taught computer gamer. He even served 25 years in the Navy before he decided to become a full-time technical program facilitator. This game programming and development teacher said computer programming is fun, especially if you have the fundamental knowledge.  

However, he added that you should not just rest on the knowledge you learned. Getting a degree is a manifestation of your past knowledge. The skills, certifications, and e-portfolio will be advantageous, but it’s best to get a broader range of experience to help you stand out.

Students will study the fundamentals of Computer Programming based on algorithm data foundation, logical engineering, and math. But you should be skilled enough when planning, writing, designing, testing, and managing software. That’s why it’s crucial that you learn at least three programming languages and that you should be proficient in C++ and JAVA. But beyond the confines of a classroom, you should have ample patience. Writing a program is not only tough, but it can also be time-consuming.

And in most cases, it will not work the first time. This programming field entails a lot of patience and unsullied skills at troubleshooting and detecting errors. You should be self-disciplined. You should be a learning worker. You should have the desire to learn yourself, the open-mindedness to brainstorm with your co-programmers, and lots of hands-on practice. 

As you work your way towards a degree in Computer Programming, it’s highly encouraged that you make a portfolio of your software work. Although this is not graded, in the future, you can show this to potential clients as proof of how capable you are with programming.

Although most computer programming careers usually need a bachelors’ degree, the US Bureau of Labor Statistics says there are also other advanced degree programs you can enroll in. Plus, aside from the usual academic setting, you can find various professional and non-profit professional certifications. Some of these certifications include:

CISCO- Certified Network Profession Routing and Switching, Certified Network Associate, Certified Network Associate Security Credential

Professional Associations- Comptia’s Security+, Software Development Associate Certification, Comptia’s Linux+, Comptia’s A+ Certification

Microsoft- Certified Solutions Associate Windows Server, Certified Solution Developer for Web Applications

Non-profit- Certified Information Security Manager, Certified Information Systems Security Professional, Certified Secure Software Lifecycle Professional Credential
