在什么情况下？


相同的规则适用于任何其他变量的字符数组。


如果数组在编译单元中并且您不想要它是在其他地方可见的
，你声明它是静态的，以避免用数组的名称污染全局的

命名空间。


如果数组有函数范围并且你希望在调用之间保留值

，你会声明它是静态的。

在早些时候，也许在C99之前，本地数组不能初始化为
，除非它被声明为静态数据。

一种可能性是您希望在后续调用函数期间记住该值

。这适用于所有类型的静态变量
而不仅仅是字符数组。另一种可能性

In what context?

The same rules apply for a character array as for any other variable.

If the array is in a compilation unit and you don''t want it to be
visible elsewhere, you declare it static to avoid polluting the global
namespace with the array''s name.

If the array has function scope and you wish the value to be retained
between calls, you would declare it static.

In the earlier days, perhaps before C99, a local array could not be
initialized unless it was declared as a static one.

One possibility is that you want the value to be remembered
during subsequent calls to the function. This applies to all kinds
of static variables not just character arrays. For another possibility
read 7.5a and 7.5b of the FAQ.
