- C language multi-threaded programming: practical optimization and troubleshooting
- C language multi-threaded programming: practical optimization and troubleshooting In modern computer systems, multi-threaded programming has become a necessary technology to improve application performance. This article will explore multi-threaded programming in C language, including optimization techniques and common troubleshooting, and provide practical cases to deepen understanding. Optimization Tips Use mutex locks to protect shared data: Using mutex locks can prevent multiple threads from accessing shared data at the same time, avoiding race conditions and data corruption. Optimize lock granularity: Using fine-grained locks (only locking the resources you really need) can improve performance. Using concurrent primitives: Using concurrent primitives such as conditional variables, semaphores, and fences can improve the readability and reliability of your code. Reduce thread creation and destruction: Creating and destroying threads requires resources, and reusing threads as much as possible can improve efficiency

- C language file operation: How to close a file?
- C language file operation: How to close a file? Preface file operation is a very important topic in C language. After opening a file, it must be closed to free up system resources and ensure data integrity. This article will guide you how to close files in C language. Syntax To close a file, use the fclose() function. The syntax is as follows: intfclose(FILE*fp); where fp is the file pointer to be closed. Return value The fclose() function returns 0 to indicate successful closing of the file, otherwise it returns EOF (indicating the end file). Practical case: Read the file and close Let's write a C program, read data from the file and display it on the screen. The program also demonstrates

- C language conditional compilation: overcome difficult problems one by one and create efficient code
- Conditional compilation is a tool that compiles C code conditionally based on the environment or settings, which can be used to adjust code, debug code, and optimize code. Preprocessor macros that implement conditional compilation follow specific syntax, common difficult problems and solutions include undefined macros, macros not extended, macros containing errors, and macro nesting. Practical cases show that conditional compilation can be used to optimize code, such as excluding error checks under specific platforms.

- Multithreaded Programming in C Language: The Art and Practice of Problem Solving
- C language multithreaded programming: Art and Practice for Solving Problems Introduction Multithreaded programming is a parallel programming technology that allows applications to perform multiple tasks simultaneously. In C language, multithreading uses the following functions to implement: pthread_create() - Create a new thread pthread_join() - Waiting for the thread to complete pthread_mutex_lock() - Get the mutex pthread_mutex_unlock() - Release the mutex case: File copying considers a C language application, which requires copying a large number of files from one directory to another. Using multithreading, we can speed up this process while performing the following steps: #include

- C language data structure: Best practices for data structures in object-oriented programming
- Best Practices for Data Structures in Object-Oriented Programming In Object-Oriented Programming (OOP), data structures are a key component used to organize and store data. Following best practices is essential to designing efficient and maintainable applications. Selecting the appropriate structure OOP provides various data structures such as arrays, linked lists, trees and graphs. For a specific task, choosing the right structure is crucial. For example: array: suitable for storing a collection of consecutive elements. Linked list: used to store discontinuous elements and can be dynamically expanded. Tree: Used to create hierarchical data structures, such as file systems. Encapsulation and hidden data structures should encapsulate member data and operations to achieve data hiding. This ensures security implemented internally and reduces the risk of external data changes. Use the appropriate data type to select

- C language conditional compilation: a detailed guide for beginners to practical applications
- C language conditional compilation is a mechanism for selectively compiling code blocks based on compile-time conditions. The introductory methods include: using #if and #else directives to select code blocks based on conditions. Commonly used conditional expressions include STDC, _WIN32 and linux. Practical case: Print different messages according to the operating system. Use different data types according to the number of digits of the system. Different header files are supported according to the compiler. Conditional compilation enhances the portability and flexibility of the code, making it adaptable to compiler, operating system, and CPU architecture changes.

- C language data structure: the key role of data structures in artificial intelligence
- C Language Data Structure: Overview of the Key Role of Data Structure in Artificial Intelligence In the field of artificial intelligence, data structures are crucial to processing large amounts of data. Data structures provide an effective way to organize and manage data, optimize algorithms and improve program efficiency. Common data structures Commonly used data structures in C language include: arrays: a set of consecutively stored data items with the same type. Structure: A data type that organizes different types of data together and gives them a name. Linked List: A linear data structure in which data items are connected together by pointers. Stack: Data structure that follows the last-in first-out (LIFO) principle. Queue: Data structure that follows the first-in first-out (FIFO) principle. Practical case: Adjacent table in graph theory is artificial intelligence
