英文:
Stack behavior when adding new thread
问题
当我们创建新线程时，堆栈会发生什么变化？
如果它进入堆栈顶部，那么它如何成为一个线程呢？如果它没有进入堆栈顶部，那么程序如何知道在哪里继续执行它的任务呢？
英文:
What happens to stack when we create new thread?
If it gets on the top of the stack, so how is it a thread?! If it doesn't get on the top of the thread, so how the program know where to continue it's job?

每个线程都有自己的堆栈。因此，如果初始线程创建了第二个线程，那么这不会影响第一个线程的堆栈。第二个线程将有它自己的堆栈。因此，在这个过程中存在两个独立的堆栈 - 每个线程一个。但是每个线程只会使用它自己的堆栈。操作系统会看到这两个线程，并在从一个线程切换到另一个线程时确保设置/使用适当的堆栈。
英文:
Each thread gets it's own stack. So if the initial thread creates a second thread, then this does not affect the stack of the first thread. And the second thread will have it's own stack. So in that process two independant stacks exist - one per thread. But each thread will only use it's own thread. The operating system sees both threads - and takes care that the proper stack is being set/used when switching from one thread to another.
