scope of a declaration
说明作用域
That portion of a program within which the declaration applies. Notes: (a) “The scope of an identifier” is often used as a synonym for “ the scope of its declaration”.
(b) A language object may not be referable throughout its scope since it may be hidden by the declaration of the same identifier in an inner block.
程序中说明适用的那一部分。注: (1) “标识符作用域”常被用作“标识符说明作用域”的同义词。 (2) 一种语言对象不一定在其整个作用域中都可被引用,这是由于该语言对象可能被内 层分程序中相同标识符的说明所遮掩。 |
