由预处理器管理的数组 [英] Array managed by preprocessor
问题描述
我的老师说C中的数组是由预处理器管理的。
Preprocesser用
替换所有数组出现(即int [10])我不理解/记得很清楚。
预处理/编译阶段阵列究竟发生了什么?
谢谢提前

Preprocesser用一些我不理解/记得不错的东西替换所有阵列出现(即int [10])。
什么是在预处理/编译阶段确实发生了数组吗?
提前致谢
嗯,这里有两种可能:
1)你误解了老师说的话。
2)你的老师非常可怕,非常错误。
我怀疑你需要修改坐在主题上;为什么不*问你的老师*?

如果我有这个数组:
a [i]
预处理器将其翻译成*(a + i)

a被翻译为costant。
谢谢

预处理器没有'不能把它翻译成任何东西。它的工作在
那个阶段完成,它已退出舞台。 []是一个成熟的运算符在
C中。它的行为定义为*(间接)和+(加法)
运算符组合使得a [i]表示*(a + i)。另外,我[a]的意思是[i]相同的
。

My teacher said that array in C is managed by preprocessor.
Preprocesser replace all array occurences (i.e. int a[10] ) with
something that I don''t understand/remember well.
What''s exactly happens with array during preprocessing/compiling stage?
Thanks in advance

Well, there are two possibilities here:
1) You misunderstood what your teacher said.
2) Your teacher is horribly, horribly wrong.
I suspect you need to revisit the subject; why not *ask your teacher*?

If I have this array:
a[i]
the preprocessor translate it, into *(a+i)
a is translated as costant.
Thanks

The preprocessor doesn''t translate it into anything. Its job is done at
that stage and it has exited stage left. [] is a full-blown operator in
C. Its behaviour is defined as the * (indirection) and + (addition)
operators combined so that a[i] means *(a+i). Also, i[a] means the same
thing as a[i].
