在C中，所有字符串都是字符数组，但反过来并不总是
true。例如：
char carray [BUFSIZ];
声明一组BUFSIZ字符。
char string [] =" Hello" ;;
声明一个char类型的数组，它有六个元素。也可以将
视为字符串，只要字符串[5] ==''\'''为真。
如果你这样做string [5] =''o''，然后string变为char数组但是
不再是字符串。如果传递给期望nul终止字符串的
函数，它将调用未定义的行为。
简而言之，字符串是一个字符数组[s]，由nul
字符终止。一个简单的字符数组没有这样的要求。
In C, all strings are character arrays but the reverse is not always
true. For example:
char carray[BUFSIZ];
declares an array of BUFSIZ characters.
char string[] = "Hello";
declares an array of type char having six elements. In can also be
treated as a string as long as string[5] == ''\0'' is true.
If you do string[5] = ''o'', then string becomes an array of char but is
no longer a string. It will invoke undefined behaviour if passed to
functions that expect a nul terminated string.
In short, a string is an array of character[s], terminated by a nul
character. A plain array of characters has no such requirement.

字符数组是一种类型（或该类型的对象）。例如，
" char [10]"是一种特殊的字符数组类型;给定char
obj [10];"，obj是这种类型的对象。
C中的字符串不是数据类型;这是一个数据布局。正如标准
所说：
_string_是一个连续的字符序列，由
终止并包含第一个空字符。

我们必须做点什么。这是事情。因此，我们必须这样做。
A character array is a type (or an object of that type). For example,
"char[10]" is a particular character array type; given "char
obj[10];", "obj" is an object of that type.
A string in C is not a data type; it''s a data layout. As the standard
says:
A _string_ is a contiguous sequence of characters terminated by
and including the first null character.

We must do something. This is something. Therefore, we must do this.

数组是纸板箱[1]。一个字符串就是你可以放入其中的东西。
你可能会把其他东西放在那里，当然 - 或者盒子可能
只是充满了垃圾 - 但它这是为了一个字符串，就像
鸡蛋盒是为鸡蛋制作的。
[1] ...除了那个，现在，数组几乎没有纸板制成。

An array is a cardboard box[1]. A string is something you might put in it.
You might put something else in there instead, of course - or the box might
just be full of junk - but it''s kind of made for a string, just like
egg-boxes are kind of made for eggs.
[1] ...except that, nowadays, arrays are hardly ever made from cardboard.
