ARGV [ARGC] ==？ [英] argv[argc] ==?

问题描述

我的教授和几个同学在争论是否的argv 是空终止与否。我的朋友写了一个小程序，它打印出来空，但另一个孩子说，他可能是简单地读入空白的存储。有人能解决这个讨论呢？

My professor and a couple of students are arguing about whether argv is null terminated or not. My friend wrote a small program and it printed out null but another kid said that he is probably simply reading into blank memory. Can someone solve this discussion?

推荐答案

从标准：

5.1.2.2.1程序启动结果
  ...结果
     - ARGV [ARGC]应是一个空指针

5.1.2.2.1 Program startup
...
-- argv[argc] shall be a null pointer.

所以，是的;的argv是空终止

So, yes; argv is null terminated
