C is a universal programming language developed by Dennis Rich in 1972 and is known for its efficiency, portability and widespread use. Reasons for learning C include its fundamentality (the foundation of many operating systems and applications), an in-depth understanding of how the internal workings of computer systems are, and its fast and efficient features (for real-time systems and embedded device programming).
Classic tutorial for getting started with C language
What is C language?
C is a common programming language developed by Dennis Rich in 1972. It is known for its efficiency, portability and wide range of applications.
Why learn C?
- The C language is the basis of many operating systems and applications, such as Linux, UNIX, and Windows.
- Understanding C language can help to gain an in-depth understanding of how computer systems work internally.
- The C language is known for its speed and efficiency, making it ideal for programming real-time systems and embedded devices.
The basics of C language
- Data Type: C language provides various data types, such as integers, characters, and floating point numbers.
- Variables: Variables store data, and you can declare them using data types.
- Operator: Operators are used to perform mathematical and logical operations.
- Statement: Statement is used to control program flow.
- Function: A function is a set of encapsulated blocks of code that are used to perform specific tasks.
C language program structure
A basic C program usually contains the following parts:
- The header file contains declarations of functions and data types.
- The main function is the entry point of the program.
- Other functions perform specific tasks.
- Global variables are visible throughout the program.
- Local variables are only visible within the scope of the function.
Steps to learn C language
- The basics of familiarity with C language.
- Practice writing simple programs.
- Learn advanced concepts such as pointers and data structures.
- Write more complex and useful programs.

Unable to log in to mysql as root
Apr 08, 2025 pm 04:54 PM
The main reasons why you cannot log in to MySQL as root are permission problems, configuration file errors, password inconsistent, socket file problems, or firewall interception. The solution includes: check whether the bind-address parameter in the configuration file is configured correctly. Check whether the root user permissions have been modified or deleted and reset. Verify that the password is accurate, including case and special characters. Check socket file permission settings and paths. Check that the firewall blocks connections to the MySQL server.
Can I install mysql on Windows 7
Apr 08, 2025 pm 03:21 PM
Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.
How to solve mysql cannot be started
Apr 08, 2025 pm 02:21 PM
There are many reasons why MySQL startup fails, and it can be diagnosed by checking the error log. Common causes include port conflicts (check port occupancy and modify configuration), permission issues (check service running user permissions), configuration file errors (check parameter settings), data directory corruption (restore data or rebuild table space), InnoDB table space issues (check ibdata1 files), plug-in loading failure (check error log). When solving problems, you should analyze them based on the error log, find the root cause of the problem, and develop the habit of backing up data regularly to prevent and solve problems.
The primary key of mysql can be null
Apr 08, 2025 pm 03:03 PM
The MySQL primary key cannot be empty because the primary key is a key attribute that uniquely identifies each row in the database. If the primary key can be empty, the record cannot be uniquely identifies, which will lead to data confusion. When using self-incremental integer columns or UUIDs as primary keys, you should consider factors such as efficiency and space occupancy and choose an appropriate solution.
Can mysql handle multiple connections
Apr 08, 2025 pm 03:51 PM
MySQL can handle multiple concurrent connections and use multi-threading/multi-processing to assign independent execution environments to each client request to ensure that they are not disturbed. However, the number of concurrent connections is affected by system resources, MySQL configuration, query performance, storage engine and network environment. Optimization requires consideration of many factors such as code level (writing efficient SQL), configuration level (adjusting max_connections), hardware level (improving server configuration).
Can mysql run on android
Apr 08, 2025 pm 05:03 PM
MySQL cannot run directly on Android, but it can be implemented indirectly by using the following methods: using the lightweight database SQLite, which is built on the Android system, does not require a separate server, and has a small resource usage, which is very suitable for mobile device applications. Remotely connect to the MySQL server and connect to the MySQL database on the remote server through the network for data reading and writing, but there are disadvantages such as strong network dependencies, security issues and server costs.
Do mysql need to pay
Apr 08, 2025 pm 05:36 PM
MySQL has a free community version and a paid enterprise version. The community version can be used and modified for free, but the support is limited and is suitable for applications with low stability requirements and strong technical capabilities. The Enterprise Edition provides comprehensive commercial support for applications that require a stable, reliable, high-performance database and willing to pay for support. Factors considered when choosing a version include application criticality, budgeting, and technical skills. There is no perfect option, only the most suitable option, and you need to choose carefully according to the specific situation.
Can mysql return json
Apr 08, 2025 pm 03:09 PM
MySQL can return JSON data. The JSON_EXTRACT function extracts field values. For complex queries, you can consider using the WHERE clause to filter JSON data, but pay attention to its performance impact. MySQL's support for JSON is constantly increasing, and it is recommended to pay attention to the latest version and features.
