推荐答案

表示退出程序并将值10返回给操作系统作为程序结果。

10可能意味着操作系统依赖于具有已定义含义的唯一数字是0，必须将其解释为成功。通常，任何非零数字都会以某种方式被解释为失败。

it means exit the program and return a value of 10 to the operating system as the programs result.

What 10 might mean is operating system dependant the only number with a defined meaning is 0 which must be interpreted as success. Normally any non-zero number is interpreted as fail in some manner.

我认为exit（10）;这里没有意义且无法访问，如果程序返回0之前的情况。

I think "exit(10);" here is meaningless and unreachable, case the program return 0 before.

抱歉你说得对，我在你的标题中回答了问题而不是你帖子中的问题。


在发布的代码中， exit（10）; 无法访问，因为返回0; 将首先发生。

Sorry you''re right I answered the question in your title not the question in your post.

In the posted code the exit(10); is unreachable and will never be executed because the return 0; will happen first.
