c++ 多线程屏幕输出会乱，且无法定位问题

解决方案：
为每个线程创建一个日志文件

#include 
#include 
#include 

void thread_func(const std::string& log_file) {
    std::ofstream log(log_file, std::ios::out | std::ios::app);
    if (!log) {
        std::cerr << "Could not open log file: " << log_file << std::endl;
        return;
    }
    log << "This is a log message from thread " << std::this_thread::get_id() << std::endl;
}

int main() {
    std::thread t1(thread_func, "log1.txt");
    std::thread t2(thread_func, "log2.txt");

    t1.join();
    t2.join();

    return 0;
}
