Description: 学习c 的绝对好书！ 第1章 声明和初始化. 1 基本类型 1 1.1 我该如何决定使用哪种整数类型？ 1 1.2 为什么不精确定义标准类型的大小？ 2 1.3 因为C语言没有精确定义类型的大小，所以我一般都用typedef定义int16和int32。然后根据实际的机器环境把它们定义为int、short、long等类型。这样看来，所有的问题都解决了，是吗？ 2 1.4 新的64位机上的64位类型是什么样的？ 3 指针声明 3 1.5 这样的声明有什么问题？ char *p1, p2; 我在使用p2的时候报错了。 3 1.6 我想声明一个指针，并为它分配一些空间，但却不行。这样的代码有什么问题？char *p; *p = malloc (10); 4 声明风格 4 1.7 怎样声明和定义全局变量和函数最好？ 4 1.8 如何在C中实现不透明（抽象）数据类型？ 5 1.9 如何生成“半全局变量”，就是那种只能被部分源文件中的部分函数访问的变量？ 5 存储类型 6 1.10 同一个静态（static）函数或变量的所有声明都必须包含static 存储类型吗？ 6 1.11 extern在函数声明中是什么意思？ 6 1.12 关键字auto到底有什么用途？ 7 类型定义（typedef） 7 1.13 对于用户定义类型，typedef和#define有什么区别？ 7 1.14 我似乎不能成功定义一个链表。我试过typedef struct {char *item; NODEPTR next;}* NODEPTR;但是编译器报了错误信息。难道在C语言中结构不能包含指向自己的指针吗？ 7 1.15 如何定义一对相互引用的结构？ 9 1.16 Struct {...} x1;和typedef struct{...} x2;这两个声明有什么区别？ 10 1.17 “typedef int (*funcptr)();”是什么意思？ 10 const限定词 10 1.18 我有这样一组声明：typedef char *charp; const charp p;为什么是p而不是它指向的字符为const? 10 1.19 为什么不能像下面这样在初始式和数组维度值中使用const值？const int n = 5; int a[n];……

Description: 运行环境：win—tc。
能实现一下功能：
1）从键盘读入数据，分析出一个单词。
2）返回单词种别（用整数表示），
3）返回单词属性（不同的属性可以放在不同的全局变量中）。
输入数据例： 0 92+data> 0x3f 00 while
正确结果：这些单词的单词种别及其属性
INT10 0
INT10 92
+ _
IDN data
> _
INT16 63
INT8 0
WHILE _
-Operating environment: win-tc. To achieve some functions: 1) read from the keyboard data, analysis of a word. 2) to return to the word of other species (expressed by an integer), 3) the return of the word attribute (the attribute can be different in different global variables). Cases of input data: 0 92+ data> 0x3f 00 while the correct result: the word of these kinds of words and their properties do not INT10 0 INT10 92+ _ IDN data> _ INT16 63 INT8 0 WHILE _

Description: function [Y,FS,NBITS,OPTS] = mp3read(FILE,N,MONO,DOWNSAMP,DELAY)
MP3READ Read MP3 audio file via use of external binaries.
Y = MP3READ(FILE) reads an mp3-encoded audio file into the
vector Y just like wavread reads a wav-encoded file (one channel
per column). Extension ".mp3" is added if FILE has none.
Also accepts other formats of wavread, such as
Y = MP3READ(FILE,N) to read just the first N sample frames (N
scalar), or the frames from N(1) to N(2) if N is a two-element vector.
Y = MP3READ(FILE,FMT) or Y = mp3read(FILE,N,FMT)
with FMT as native returns int16 samples instead of doubles
FMT can be double for default behavior (to exactly mirror the
syntax of wavread).

Description: 在这个更新的代码，新功能，包括colorbar，samesize包括向量plottting...
％更新版本$日期：5月18日，2011年由梁枯盎斯蒂文斯技术学院
％更新1：更改int8到Int16的colormap的是，当电流超过64个大，这将导致错误
％更新2：加入 samesize 为使所有的向量samesize
％更新3：添加colorbar相应的开方的幅度（ü^2+ V键^ 2）
％更新4：错误修复，当你为h = quiverc，这是行不通的。
------------------------------------------------- -----------
-In this updated code,new features including colorbar, samesize vectors plottting are included
Updated version $Date: May 18th,2011 by Liang Kuang at Stevens Institute of Tech
Update 1: Change int8 to int16 when current colormap is bigger than 64,which will cause error
Update 2: Added samesize for making all the vectors the samesize
Update 3: Add colorbar corresponding the the magnitude of sqrt(u^2+v^2)
Update 4: bug fixed,when you do h=quiverc, it doesn t work.

Description: In mathematics, the greatest common divisor (gcd), also known as the greatest common factor (gcf), or highest common factor (hcf), of two or more integers(at least one of which is not zero), is the largest positive integer that divides the numbers without a remainder. For example, the GCD of 8 and 12 is 4. here GCD algorithm of int16 bit is implemented in vhdl. This has module like fsm(finite state machine),datapath which are used to compute greatest common divisor of two numbers.

Description: Was used to test a memory scanner (Like cheat engine) Simple for hook testing, beginner pointer searching, etc.. Great to make something like this if you don t know a lot about how memory is stored and what not. Basically, the program itself defines a few values and adds a random number to each value type every time you read the console. Has int16, int32, int64, single, and double. Very simple, even a small child can read the source :)
