哪里是用C auto关键字? [英] Where is the C auto keyword used?
问题描述
在我的大学时代我读了汽车
关键字,并在时间过程中,我居然忘了是什么了。它被定义为:
In my college days I read about the auto
keyword and in the course of time I actually forgot what it is. It is defined as:
一个局部变量定义为具有
当地寿命
defines a local variable as having a local lifetime
我从来没有发现它正在使用的任何地方,是不是真的使用,这样的话它在哪儿使用,在什么情况下?
I never found it is being used anywhere, is it really used and if so then where is it used and in which cases?
推荐答案
汽车
像修改器静态
。它定义了存储类变量。但是,由于局部变量默认为汽车
,你通常不需要手动指定它。
auto
is a modifier like static
. It defines the storage class of a variable. However, since the default for local variables is auto
, you don't normally need to manually specify it.
