Basics of Computer Programming

Basics of Computer Programming

Computer programming provides instructions known as code that instructs how an application, application, or software program should perform. In simple words, it is a set of instructions that facilitate actions.

Coding or programming does not mean creating only an application or software program but anything from a web page to a picture. That is why computer science is known as a mixture of Science and Art. The level of computer programming depends on its code, and it can be as easy as adding two numbers and as complex as creating challenging games.

Computers have evolved a long way, from simple word processing and spreadsheet functions to supercomputers completing millions of daily transactions. Computers can do anything, but only upon what programmers make them do.

Role of programmers

Role of programmers

Computer programmers create instructions by writing codes for computer applications to perform. They use specialized languages to communicate with the computer or applications. According to research, some of the tasks done by computer programmers are:

  • Testing software performance.
  • Writing computer programming code.
  • Resolving computer software problems.
  • Modifying software to improve performance.
  • Collaborating with other techies to resolve information technology issues.

Programming languages to learn

Programming languages to learn

Which language to learn depends on your goal and what you want to create or solve. Some of the common programming languages include:

Some of these languages are easy to learn, whereas some are complex; however, all are useful depending on your goal!

Categories of Computer programming

Programming languages are grouped in a variety of categories. Some of them include:

  • Machine language- A low-level language consisting of 0’s and 1’s (binary). High-level languages are compiled into machine code to be executed by the computer.
  • Assembly language- A low-level language that is compiled by an assembler. Assemblers translate human code to machine code.
  • Procedural languages– The approach goes through procedures before a program is executed on the computer.
  • Scripting languages– The languages often don’t need to be compiled but rather interpreted. Interpreted means an interpreter will read and execute the code instead of being compiled into machine code.
  • Functional languages– This works with building complex programs through a collection of smaller functions.
  • Object-oriented languages– This works with building programs around collections of objects.

How to become a computer programmer?

You can opt for a degree to incline towards the professional line. Otherwise, as a passion, or a sidekick, you can also learn by self-study. However, as a programmer, you always need to be updated with the trending language. So, you need to study throughout your professional life. Being a programmer, you should plan, write codes, design, test, and manage software. As a beginner, you should know at least three to four primary programming languages, along with Data Structures, algorithms, math, and logical engineering.

The first and foremost quality you must have as a programmer is a patience. This field requires more patience and the ability to find errors and resolve the issues. You need to be disciplined, be motivated to learn new things, brainstorm ideas, and be a learning person.

Your theoretical knowledge is not enough to become a professional Computer Programmer, and you need to have hands-on practical experience and work on real-world projects. You have to practice a lot and constantly adapt to new trends.

You should create a portfolio by working on projects which will help you as an employee, as this portfolio will prove your coding skills. As I said earlier, not only coding skills but also testing of software, graphics, and many more skills should be included.

Types of Programming jobs

  • Web Developer- These types of programmers build applications for the web. They will work with HTML, CSS, JavaScript, PHP, Python, and more. Salaries will vary according to location, but it is undoubtedly a high-paying job.
  • Mobile Developer- These types of developers build applications for mobile devices. They work with React Native, Swift, Flutter, Java, and Kotlin.
  • Game Development- These programmers build custom games for mobile, desktop, and game console use. Programming languages include C++, C#, and Lua.
  • Computer Systems Engineer- This role is a mix of computer science and engineering that work on complex business applications. Programming languages include Python, Java, and C++.

Skills a programmer should have

  • Writing clean and efficient code.
  • Ability to find errors.
  • Fixing bugs.
  • Patience
  • Problem-solving ability
  • Testing applications
  • Good communication and listening skills
  • Co-operation with team

Front-end and Back-end development

Front-end development is writing codes for visual elements, and it is the graphics that users can see and interact with. As a front-end developer, you need to be creative because it is all about how a website or an application looks and feels.

Examples of front-end development include good-looking fonts on a web page, the slider, or even the dropdown menu. Everything depends on the front-end developer, from the color theme to the page’s layout to typography.

The three main languages for front-end development are:

Back-end development is about writing codes for how should a website perform or operate. Back-end development is invisible to users, and it also includes working with databases that store pieces of information.

The three main languages for back-end development are:

  • PHP
  • Ruby
  • Python
  • .NET

The best example of both Front-end and Back-end development is Amazon. When you visit this website, how the web page looks, what you are searching, filtering or the entire process of buying is when you interact with the front-end work. On the other side, the functionality such as recommendations, payment details, or payment processing, all of these is the work of back-end developers.

A developer who knows both front-end and back-end is known as a full-stack developer.

Why you should take a Computer Course?

In this tech-leading world, computer-related jobs are surging, and the technical job is a guaranteed role in this era. According to research, out of the top 25 jobs, the 8 were of tech positions.

There is a massive number of learning resources available for programming. From online video tutorials to dedicated courses, almost all educational companies provide it.

You do not need to get a job in a technically-expert role, but programming skills offer you many more job roles that are less technical. Computer programming skills can help you in many ways, and you will gain lots of benefits from it.

About Programming certificates

According to the U.S. Bureau of Labor Statistics (BLS), most computer programming positions require at least a bachelor’s degree. However, in addition to these degrees, certifications are also necessary. Some of the professional certifications include:

  • CISCO- Certified Network Associate, Certified Network Profession Routing and Switching, Certified Network Associate Security Credential.
  • Microsoft– Certified Solution Developer for Web Applications, Certified Solutions Associate Windows Server.
  • Professional Associations– Software Development Associate Certification, Comptia’s Security+, Comptia’s A+ Certification, Comptia’s Linux+.
  • Nonprofit– Certified Information Systems Security Professional, Certified Information Security Manager, Certified Secure Software Lifecycle Professional Credential

Wrapping up

I hope that I have explained the basics of computer programming and its career options. Despite the job you want to go for, programming skill is beneficial to your resume.

Computer programming is a gratifying and analytical subject that will help you as a student and also if you want to pursue it professionally. There are different fields of programming. Depending on how you want to work with it, you can either pursue a formal education, self-study, or earn certificates.

Technology has already taken over everything, and soon every job option will include technical roles. So, you must start prepping for it now. I hope you enjoy this article.
