内部级别声明的存储类说明符Storage-Class Specifiers for Internal-Level Declarations

可以对内部级别的变量声明使用四个 storage-class-specifier 终止符中的任何一个。You can use any of four storage-class-specifier terminals for variable declarations at the internal level. 如果省略此类声明中的 storage-class-specifier,则默认的存储类将是 auto。因此,很少在 C 程序中显示关键字 auto。When you omit the storage-class-specifier from such a declaration, the default storage class is auto. Therefore, the keyword auto is rarely seen in a C program.
