Preface
If you are new to programming, you may ask, what is a programming language? Why learn a programming language? What programming languages are there? What's the difference between them? Don't worry, the editor will answer you one by one.
Programming language concepts
A programming language is a man-made language used to communicate with computers. It allows us to direct the computer to perform the tasks we want in a standardized and logical way. For example, we can use programming languages to develop websites, mobile applications, games, artificial intelligence, etc. Programming language is a creative and practical skill that allows us to realize our ideas and solve various problems.
Classification of programming languages
There are many kinds of programming languages, which can be divided into different types according to different standards. For example, according to the distance between a programming language and a computer, it can be divided into low-level languages and high-level languages. Low-level languages are languages that are closer to computers. They are generally more difficult to learn and use, but are faster and more efficient. High-level languages are languages that are more human-like; they are generally easier to learn and use, but are slower and less efficient. For example, assembly language is a typical low-level language, and Python is a typical high-level language.
In addition, according to the programming paradigm supported by the programming language, it can be divided into imperative languages and declarative languages. Imperative languages are languages that tell computers how to do things. They are usually more specific and detailed, but more complex and verbose. Declarative languages are languages that tell the computer what to do. They are usually more abstract and concise, but more difficult to understand and control. For example, C++ is a typical imperative language, and SQL is a typical declarative language.
Of course, there are many other classification standards. For example, it can be divided into interpreted languages and compiled languages according to the execution method, and it can be divided into general-purpose languages and special-purpose languages according to the application fields, etc. The editor will not introduce them one by one here.
Common programming languages
Currently, the more popular programming languages in the Internet field include the following:
-
Python: Python is a concise and flexible programming language that can be used in various fields and tasks, such as artificial intelligence, data science, web development, automated testing, etc. Python is also friendly to many other programming languages and libraries, such as C, NumPy, TensorFlow, etc. Python's development direction is to maintain its ease of use and versatility while improving its performance and stability.
-
C++: C++ is a powerful and complex programming language that can be used for various high-performance and low-level application development, such as game development, graphics rendering, system programming, etc. C++ is also a competitor of many other programming languages and tools, such as Rust, Unreal Engine, Qt, etc. The direction of C++'s development is to maintain its speed and flexibility while improving its simplicity and safety.
-
JavaScript: JavaScript is a programming language that runs in the browser. It can be used for various web development and dynamic content generation, such as web interaction, animation effects, data visualization, etc. JavaScript is also the leader of many other programming languages and frameworks, such as TypeScript, React, Angular, etc. The direction of JavaScript's development is to maintain its popularity and flexibility while increasing its standardization and consistency.
-
PHP: PHP is a programming language that runs on the server side. It can be used for various web development and dynamic content generation, such as website backends, e-commerce, content management systems, etc. PHP is also a competitor of many other programming languages and frameworks, such as Python, Ruby, Laravel, etc. The development direction of PHP is to maintain its practicality and easy extensibility, while improving its quality and security.
-
SQL: SQL is a programming language used to operate relational databases. It can be used for various data analysis and report generation, such as querying data, updating data, deleting data, etc. SQL is also a collaborator with many other programming languages and tools, such as Java, Python, Excel, etc. The development direction of SQL is to maintain its versatility and stability while improving its functionality and flexibility.
-
Assembly language: Assembly language is a programming language that directly corresponds to machine code. It can be used for various low-level and efficient application development, such as driver, disassembly, encryption, etc. Assembly language is also the basis for many other programming languages and tools, such as C, IDA Pro, OllyDbg, etc. The development direction of assembly language is to maintain its accuracy and efficiency while improving its readability and portability.
The difference between programming languages
Different programming languages have different characteristics, advantages and disadvantages, and they are suitable for different application scenarios and users. For example, Python is suitable for beginners and people engaged in data analysis because it is easy to learn and has rich libraries and communities. C++ is suitable for advanced developers and game developers because it is fast and flexible, with powerful features and control. JavaScript is suitable for web developers and front-end developers because it is popular, flexible, has extensive support and standards. SQL is suitable for database administrators and data analysts because it is versatile and stable, with concise syntax and logic.
Of course, these are just some simple examples. In fact, each programming language has its own advantages and disadvantages, as well as its own scope of application and limitations. When choosing a programming language, you should comprehensively consider it based on your own needs, goals, interests, level and other factors.
No programming language is perfect, and no programming language is useless. In the process of learning a programming language, you must maintain an open and curious mind. Don't blindly follow trends or reject new things. Try to understand more, compare more, practice more, and create more.
Summarize
I hope this article can help you understand the diversity and characteristics of programming languages and choose the programming language that suits you. Of course, this article is just a simple introductory introduction. If you want to learn a certain programming language in depth, you need to consult more information and tutorials for practice and practice. Programming language is an interesting and useful skill that allows you to create a variety of applications and products, and also allows you to enjoy solving problems and creating value. Happy studying!
