In C, the POD (PlainOldData) type refers to a type with a simple structure and compatible with C language data processing. It needs to meet two conditions: it has ordinary copy semantics, which can be copied by memcpy; it has a standard layout and the memory structure is predictable. Specific requirements include: all non-static members are public, no user-defined constructors or destructors, no virtual functions or base classes, and all non-static members themselves are PODs. For example structPoint{intx;inty;} is POD. Its uses include binary I/O, C interoperability, performance optimization, etc. You can check whether the type is POD through std::is_pod, but it is recommended to use std::is_trivia after C 11.

In Linux systems, 1. Use ipa or hostname-I command to view private IP; 2. Use curlifconfig.me or curlipinfo.io/ip to obtain public IP; 3. The desktop version can view private IP through system settings, and the browser can access specific websites to view public IP; 4. Common commands can be set as aliases for quick call. These methods are simple and practical, suitable for IP viewing needs in different scenarios.

The key to writing C# code well is maintainability and testability. Reasonably divide responsibilities, follow the single responsibility principle (SRP), and take data access, business logic and request processing by Repository, Service and Controller respectively to improve structural clarity and testing efficiency. Multi-purpose interface and dependency injection (DI) facilitate replacement implementation, extension of functions and simulation testing. Unit testing should isolate external dependencies and use Mock tools to verify logic to ensure fast and stable execution. Standardize naming and splitting small functions to improve readability and maintenance efficiency. Adhering to the principles of clear structure, clear responsibilities and test-friendly can significantly improve development efficiency and code quality.

In C, there are three main ways to pass functions as parameters: using function pointers, std::function and Lambda expressions, and template generics. 1. Function pointers are the most basic method, suitable for simple scenarios or C interface compatible, but poor readability; 2. Std::function combined with Lambda expressions is a recommended method in modern C, supporting a variety of callable objects and being type-safe; 3. Template generic methods are the most flexible, suitable for library code or general logic, but may increase the compilation time and code volume. Lambdas that capture the context must be passed through std::function or template and cannot be converted directly into function pointers.

To use C for high frequency trading (HFT), focus on performance, stability, and low latency. 1. Master the underlying system knowledge, including CPU caching mechanism, system call overhead and using perf tools to analyze hot spots; 2. Optimize compiler options and code structure, such as enabling -O3, LTO, reducing the use of virtual functions, and optimizing the structure layout; 3. Use zero-copy technology, non-blocking UDP, batch data processing to achieve low-latency network communication, and use shared memory or RDMA if necessary; 4. Emphasize debugging and testing strategies, including static analysis, unit testing, stress testing and light-weight logging, and verify the correctness of logic in combination with the simulator.

In C, the lambda capture clause controls how external variables are introduced into the lambda function through values, references, or default patterns. 1. The capture list is at the beginning of the lambda expression and is used to capture variables in the external scope for internal use of the lambda. 2. The variable will be copied through value capture ([var]). Modifications in the lambda will not affect the original variable. If you need to modify the copy, you need to use the mutable keyword. 3. By reference capture ([&var]) allows lambda to directly modify the original variable, but there is a risk of dangling references. 4. Default capture mode [=] automatically captures all used variables by value, [&] automatically captures by reference, but should be used with caution to avoid potential errors.
