用C语言编写的并行计算π值的代码，并附多次运算结果的分析和比较(Using C language code for parallel computing π value, along with many of the analysis and comparison of operation results)

用linq实现 从数组中随机选n个 元素 示例

说明：  青蛙源代码，是当前最完整的，供大家分享，绝对简单(Frog source code, is currently the most complete, for everyone to share, absolutely simple)

用编程软件matlab写的一个yy样条函数，参考(Matlab programming software to write with a yy spline function, reference)

这是我又一个编程,通过它,你可以详细了解c++builder的使用 初学,请大家指教,(This is my another programming, through it, you can learn more about the use of c++ builder beginner, please advise,)

将txt导入到程序中，程序以txt文件中两列数据的第一列为横坐标，第二列为纵坐标生成对应的曲线，利用QCustomplot绘制；同时右端窗口可导入GIF图并实现播放和暂停。

之前下载了winform实现Echart统计图（基于webBrowser）有了echart在winform的应用。但发现他实际上是静态页面的，统计图未有数据交互功能。本例主要通过C#winform给echart赋值，实现数据动态交互。 

非常经典的讲解编程风格的一本书，欢迎大家下载(Programming style is very classic, a book to explain, are welcome to download)

说明：  编写一个程序，包括两个线程，一个线程用于模拟内存分配活动，另一个用于跟踪第一个线程的内存行为，要求两个线程之间通过信号量实现同步，模拟内存活动的线程可以从一个文件中读出要进行的内存操作。将VirtualAlloc函数的参数flAllocationType分别设置为MEM_RESET,MEM_TOP_DOWN,将flProtect参数分别设置为PAGE_GUARD,PAGE_NOACCESS,PAGE_NOCACHE，执行并查看内存分配的结果。(Write a program that consists of two threads, one thread is used to simulate the memory allocation activities, one for tracking the memory behavior of the first thread, requiring between two threads synchronize through semaphores to simulate the activities of the thread of memory from a read the file memory operations to be carried out. FlAllocationType the VirtualAlloc function parameters were set to MEM_RESET, MEM_TOP_DOWN, will flProtect parameters are set to PAGE_GUARD, PAGE_NOACCESS, PAGE_NOCACHE, execute and view the results of memory allocation.)
