问题
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?
回答1:
From the Standard:
5.1.2.2.1 Program startup
...
-- argv[argc] shall be a null pointer.
So, yes; argv is null terminated
回答2:
According to the standard, "argv[argc] shall be a null pointer" (5.1.2.2.1).
