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
