寻找一本重点关注数据类型的C教科书 [英] Looking for a C textbook with emphasis on data types
问题描述
我本来应该教一个不寻常的倾向的入门C课程，
并且找不到合适的教科书。这个课程将开始传统上使用变量，循环，条件，结构，
指针和fopen / fclose。然而，除此之外，我所看到的每门课程和b * b b教科书对数据*结构都很重要*，如果有的话，会轻易触及其他
主题。而我需要强调数据*类型*，
将它们转换为另一个，并进行位操作。
结束课程我不在乎我的学生是否知道链表是什么，让
单独一个二叉树，但他们必须对ASCII有很好的理解，
二进制和十六进制。例如，它必须向他们清楚为什么数字
353实际存储为0x01 0x61如果它是和INT，但是0x33 0x35 0x33
如果它是's CHAR *。或者为什么将数字CHAR转换为INT涉及
减去48 - 而不是30，如前面的例子所示。
是否有教科书强调数据类型，位和
十六进制，还是我注定要写自己的？

课程我不在乎我的学生知道链表是什么，让
一个二进制树，但他们必须对ASCII有很好的理解，
为什么？这与C无关。
二进制和十六进制。例如，它必须向他们清楚为什么数字
353实际存储为0x01 0x61如果它是和INT，
那里C中没有INT类型.353可能存储为0x0161，但可能存储为0x6101,0x00006101（即4个八位位组），或者为0x61010000（小
$ b $） b endian，四个八位字节到int），或者以其他任何方式。
但是0x33 0x35 0x33如果它是CHAR *。
C没有CHAR类型。要存储字符3，5和3，您需要
三个字节的存储空间。指向第一个字符的指针将是/ b $ b /不是/具有值0x333533（除非通过一些惊人的巧合）。
或者为什么将数字CHAR转换为INT涉及
减去48 -
它没有。如果你的意思是将''4'变成4或'6'变成6，它会涉及
减去''0'而不是48。
而不是30，正如前面的例子所暗示的那样。
是否有一本教科书如此强调数据类型，位和
十六进制，还是我注定要写自己的？
我的话。拜托，拜托，请不要自己写，直到你了解你在说什么。

谁叫你减去30？
你必须减去''0''。当你在读取
时，你会错过''0x'。
应该是0x30。

哎呀...
请不要,,,为了上帝的缘故。
去读取圣书 ，C编程语言，由K& R.

想想孩子们!!!
I am supposed to teach an introductory C course with an unusual slant,
and have trouble finding an appropriate textbook. The course will begin
traditionally enough with variables, loops, conditionals, structures,
pointers and fopen/fclose. Beyond that, however, every course and
textbook I had seen is heavy on data *structures*, and touches on other
topics lightly if at all. Whereas I need to stress data *types*,
converting them one into the other, and bit manipulation. By the end of
the course I do not care if my students know what a linked list is, let
alone a binary tree, but they must have good understanding of ASCII,
binary and hexadecimal. For example, it must clear to them why number
353 is actually stored as 0x01 0x61 if it''s and INT, but 0x33 0x35 0x33
if it''s a CHAR*. Or why converting a numeric CHAR into an INT involves
subtracting 48 -- and not 30, as previous example might suggest.
Is there a textbook with such emphasis on data types, bits, and
hexadecimal, or am I doomed to writing my own?

binary and hexadecimal. For example, it must clear to them why number
353 is actually stored as 0x01 0x61 if it''s and INT,There is no INT type in C. 353 might be stored as 0x0161, but it might be
stored as 0x6101, 0x00006101 (i.e. in 4 octets), or as 0x61010000 (little
endian, four octets to the int), or in any of a zillion other ways.
but 0x33 0x35 0x33 if it''s a CHAR*.C has no CHAR type. To store the characters ''3'', ''5'', and ''3'', you need
three bytes of storage. A pointer to the first of these characters will
/not/ have the value 0x333533 (unless by some astounding coincidence).
Or why converting a numeric CHAR into an INT involves
subtracting 48 --It doesn''t. If you mean turning ''4'' into 4 or ''6'' into 6, it involves
subtracting ''0'', not 48.
and not 30, as previous example might suggest.
Is there a textbook with such emphasis on data types, bits, and
hexadecimal, or am I doomed to writing my own?Oh my word. Please, please, please don''t write your own, until you
understand what you''re talking about.

converting them one into the other, and bit manipulation. By the end of
the course I do not care if my students know what a linked list is, let
alone a binary tree, but they must have good understanding of ASCII,
binary and hexadecimal.Which of these is ''C'' ?

byte ordering ?
>but 0x33 0x35 0x33
if it''s a CHAR*.How can number 353 be char * ??
>Or why converting a numeric CHAR into an INT involves

You have to subtract '' 0''. And you would have missed '' 0x'' while you
were reading.
It should have been 0x30.
Is there a textbook with such emphasis on data types, bits, and
hexadecimal, or am I doomed to writing my own?Ooops...
No please,,, for god''s sake.
Go and read " the holy book" , The C programming language, by K & R.
