39. SD卡实验

VB扑克牌游戏（纸牌游戏）源码下载，程序非常简单，因此如果你是VB新手的话，你会比较喜欢的。游戏玩法：左键翻牌或选牌，右键在目标位置放牌，双击浮在最上的已翻开的牌可按规则自动放牌到右上角。Codefans.net截图如上所示。

书本的习题代码以及课件等等c有关的学习资料(Exercise code for books)

python核心编程，本书详细介绍了python编程的语法结构，并有大量的例子作为参考。(python core programming, the book details the python programming grammatical structure, and there are plenty of examples as a reference.)

VB 透过GPIB 和仪器通信，代码比较简单，仅供参考。谢谢(VB communicates with the instrument through GPIB. The code is relatively simple and is for reference only. Thank you)

一个非常流行的游戏，用C++开发的，适用于初学者学习与研究。-a very popular game, with C development and applicable to beginners learning and research.

说明：  浮点数的表示与算术运算算法分析，要求理论推导与程序模拟。 算术运算包括字符串到浮点数、浮点数到字符串的转换，加、减、乘、除四则运算等。要有说明文档，包括算法证明、程序框图、使用方法、特殊处理(溢出、数位扩展)、实例分析等等。字符串转换可能稍难。 typedef unsigned int dwrd; #32-bit char* ftoa(dwrd); dwrd atof(char*); dwrd fadd(dwrd, dwrd); dwrd fsub(dwrd, dwrd); dwrd fmul(dwrd, dwrd); dwrd fdiv(dwrd, dwrd);(The representation of floating-point number and the analysis of arithmetic operation algorithm require theoretical derivation and program simulation. Arithmetic operations include string to floating point, floating point to string conversion, addition, subtraction, multiplication, division and so on. Documentation should be provided, including algorithm proof, program block diagram, usage, special handling (overflow, digital expansion), case analysis, etc. String conversion can be slightly difficult. typedef unsigned int dwrd; #32-bit char* ftoa(dwrd); dwrd atof(char*); dwrd fadd(dwrd, dwrd); dwrd fsub(dwrd, dwrd); dwrd fmul(dwrd, dwrd); dwrd fdiv(dwrd, dwrd);)
