他们真的是教程。 L_BitWise.zip包含一个文本文件，157行
long，这确实是按位运算符的教程。 L_ptr2.zip包含
一个文本文件L_ptr.txt，这是一个174行指针教程。
我看起来不是非常接近在他们中的任何一个，但是第一段
指针tute看起来并不乐观：
" C中的指针是一个变量，它保存着另一个变量的地址
在内存中。它们对于动态分配的内存非常有用，可能需要在不再需要时释放
，链接列表，写入程序外部的内存，并允许调用的函数操作数据
范围之外的变量。这些有很多用途，对于在C中成功编程是必要的。
哦，亲爱的我自己。

Usenet是一个奇怪的放置" - dmr 1999年7月29日
They really are tutorials. L_BitWise.zip contains one text file, 157 lines
long, which is indeed a tutorial on bitwise operators. L_ptr2.zip contains
one text file, L_ptr.txt, which is a 174-line tutorial on pointers.
I didn''t look very closely at either of them, but the first paragraph of
the pointer tute does not look promising:
"A pointer in C is a variable which holds the address of another variable
in memory. They are useful for dynamicly allocated memory which may be
deallocated when nolonger needed,linked lists,writing to memory external to
the program,and allowing invoked functions to manipulate the data of
variables outside their scope. These have many uses and are necessary to
successfull programming in C."
Oh deary deary me.

One of yours (the first one), and my second is a rather harsher take on the
same subject as your one-and-a-halfth point, because pointer values need
not even represent object addresses, let alone variable addresses - they
could be indeterminate, or null, or function pointers. My third rather
depends on what you mean by "variable", but if the last clc discussion on
the matter is anything to go by, the bit about scope is wrong too.

这正是MisterE所做的。
我既不知道也不关心指针是否是值，变量，键入或
对象。但这并没有阻止我非常有效地使用它们。

This is exactly the point MisterE was making.
I neither know nor care whether a pointer is a value, variable, type or
object. But that hasn''t stopped me using them quite effectively.
