A thread in C++ refers to a sequence of executions that execute concurrently. A thread library, the header file, is introduced in the C++11 standard for creating and managing threads.
You can use the member functions of the thread object to manage the thread, such as join is used to wait for the execution of the thread to complete, detach is used to separate the thread and so on. In addition, you can also pass parameters to the thread function by calling the thread function with additional parameters.
Concurrent execution of threads can improve program performance and responsiveness, but also requires careful handling of shared data and synchronization issues. The C++ standard library also provides other classes and functions for thread synchronization, such as std::mutex, std::condition_variable, etc., to help handle shared data access between threads.
Note that threaded programming is complex and requires careful consideration and handling of various concurrency issues. When writing multithreaded code, be careful with shared data and avoid race conditions, deadlocks, etc.
To use threads in C++, you need to include the header file and use the std::thread class to create a thread object. Here is a simple example:
#include <iostream>
#include <
