Well, turns out that with arrays, not to make this too trippy too soon, but Arg V bracket something is a string, you can also use square bracket notation to go to a specific letter in a string, because little teaser a string is just an array.

好的，结果用那个数组，不要使这个很快引起幻觉，但是Argv什么的，是一个字符串，你也可以用方括号定位到,字符串中的一个特定的字母，因为一个字符串只是一个数组。
