Computer programming is the process of creating sets of instructions, called codes, that tell a computer how to perform specific tasks or operations. It involves writing, testing, and maintaining sequences of commands using programming languages, such as Python, Java, or C++. Programmers use their knowledge of programming languages and problem-solving skills to develop software applications, websites, games, and other computer-based systems. Programming enables computers to execute desired actions, automate processes, and solve complex problems, making it a fundamental skill in the world of technology.
The prerequisites to learn programming depend on the programming language or technology you are interested in learning. However, some general skills that can be helpful include:
Additionally, if you are new to programming, understanding basic math concepts such as algebra, geometry, and trigonometry can be helpful.
There are many different types of computer programming, and different languages and technologies are used for different purposes. Some of the main types of computer programming include:
Systems Programming: Systems programming involves writing code that interacts directly with the underlying hardware of a computer, such as device drivers, operating systems, and embedded systems.
Application Programming: Application programming involves writing code for specific software applications, such as web applications, mobile apps, desktop apps, and games.
Game Programming: Game programming specifically involves the development of video games, including the creation of game engines, programming of game logic, and development of game assets.
Database Programming: Database programming involves writing code that interacts with databases, such as SQL and other data management-related languages.
The choice of programming language to learn depends on your goals and what you want to do with it. Here are a few things to consider when choosing a programming language to learn.
The most popular programming languages for beginners are :
Python: It is known for its simplicity and readability, it's a great language for beginners to learn.
Java: It is similar to C++, it's widely used in enterprise and mobile application development.
Scratch: It is visual programming language designed for children and beginners to learn programming concepts.
C#: C# is a great language for beginners because of its simplicity and the vast amount of resources available.
Keep in mind that the best programming language to learn is the one that you enjoy and can stick with. It depends on what you want to do with programming, some languages are better suited for different tasks.
Competitive programming is a fun and challenging way to improve your programming skills and it can also be a way to get noticed by potential employers.
It is not only a way to improve problem-solving skills, but also increases a programmer's chances to crack software development-related interviews, since a lot of questions in software development interviews are based on problem-solving, and a programmer who has competed in online programming competitions has good experience solving complex problems.
The salary you can earn after learning a programming language can vary greatly based on factors such as location, experience, and the specific language you have learned. In general, the average salary for an American programmer can range from around $60,000 to $150,000 or more per year, depending on the country, region, and industry.

The popularity of programming languages is changing over time, but here is a list of some of the most popular programming languages that are currently in high demand:
besides this, new languages and technologies like Rust, Swift, and Dart have been gaining popularity too.
Generally, certifications can be helpful, but they're not a required for every programmer. a programmer's skills and experience are more important than any certification they may have. but having a certification can demonstrate to employers that a programmer has a certain level of knowledge or expertise in a specific programming language or technology. It can also be used as a way to validate the skills that a programmer has learned on the job.
Web design and web development are two different but related fields that involve creating & designing websites. It's essential to understand what you are looking for in terms of the web. If you want to focus on the look and feel of the website, web design might be a good fit for you. If you're interested in the technical side of building websites, web development might be a better fit.
Computer Science and programming are related, but they are not the same thing. Computer Science is the study of computers and computational systems, including their theoretical and practical foundations. It includes a wide range of topics, like algorithms, programming languages, software engineering, computer architecture, artificial intelligence, and more. on the other hand, Programming is the process of creating instructions that a computer can execute. It involves writing code in a programming language, using techniques and methodologies learned from computer science.
programming is a necessary part of computer science, while computer science has much more than programming.
