How to use the chrono library in C?
Apr 28, 2025 pm 10:18 PM
Using the chrono library in C can allow you to control time and time intervals more accurately. Let's explore the charm of this library. C's chrono library is part of the standard library, which provides a modern way to deal with time and time intervals. For programmers who have suffered from time.h and ctime, chrono is undoubtedly a boon. It not only improves the readability and maintainability of the code, but also provides higher accuracy and flexibility. Let's start with the basics. The chrono library mainly includes the following key components: std::chrono::system_clock: represents the system clock, used to obtain the current time. std::chron

How to measure thread performance in C?
Apr 28, 2025 pm 10:21 PM
Measuring thread performance in C can use the timing tools, performance analysis tools, and custom timers in the standard library. 1. Use the library to measure execution time. 2. Use gprof for performance analysis. The steps include adding the -pg option during compilation, running the program to generate a gmon.out file, and generating a performance report. 3. Use Valgrind's Callgrind module to perform more detailed analysis. The steps include running the program to generate the callgrind.out file and viewing the results using kcachegrind. 4. Custom timers can flexibly measure the execution time of a specific code segment. These methods help to fully understand thread performance and optimize code.
How to optimize code
Apr 28, 2025 pm 10:27 PM
C code optimization can be achieved through the following strategies: 1. Manually manage memory for optimization use; 2. Write code that complies with compiler optimization rules; 3. Select appropriate algorithms and data structures; 4. Use inline functions to reduce call overhead; 5. Apply template metaprogramming to optimize at compile time; 6. Avoid unnecessary copying, use moving semantics and reference parameters; 7. Use const correctly to help compiler optimization; 8. Select appropriate data structures, such as std::vector.

How to implement loosely coupled design in C?
Apr 28, 2025 pm 09:42 PM
To implement loose coupling design in C, you can use the following methods: 1. Use interfaces, such as defining the Logger interface and implementing FileLogger and ConsoleLogger; 2. Dependency injection, such as the DataAccess class receives Database pointers through the constructor; 3. Observer mode, such as the Subject class notifies ConcreteObserver and AnotherObserver. Through these technologies, dependencies between modules can be reduced and code maintainability and flexibility can be improved.
