校运动会代码（部分），使用VB编程，由学生自己开发(yundonghui)

说明：  用c语言实现电机仿真－基于恒定磁链的转子磁链控制。(Using c language realize electrical simulation- based on a constant flux of the rotor flux control.)

统计字母出现的频率，统计英文文章相应字母出现概率(Statistics the frequency of occurrence of English letters, the letters corresponding to probability statistics)

实现大小写互换，即输入大写子母程序会自动转成小写子母(Realization case swap)

抑制载波型差分相位调制，借鉴了主成分分析算法（PCA），有CDF三角函数曲线/三维曲线图。( Suppressed carrier type differential phase modulation, It draws on principal component analysis algorithm (PCA), There CDF trigonometric curve/3D graphs.)

VC抽奖程序源代码，绝对可用，而且代码很全(VC lottery program source code is absolutely free , and the code is all )

编写C程序，随机给出n*n的邻接矩阵，并打印输出邻接矩阵，以及有向图的边的个数，每个顶点的度，并判断该图中是否存在Euler回路： （1）如果为n阶，则随机产生一个n*n的邻接矩阵； （2）输出邻接矩阵，边的个数，每个顶点的度以及图中是否存在Euler回路。 这个题目涉及到了两个主要的知识点，一个是数据结构中的有向图的邻接矩阵的创建，还有就是离散数学中的Euler回路的判定定理。(The preparation of C procedures, were randomly given n* n s adjacency matrix and adjacency matrix printouts, as well as to map the number of edges, each vertex degrees, and determine the existence of the map Euler circuit: (1) If for n-order, then randomly generated a n* n adjacency matrix (2) output adjacency matrix, the number of edges, each vertex of degree as well as map the existence of Euler circuit. This topic relates to two main points of knowledge, a data structure of digraph adjacency matrix of creation, there is discrete mathematics in the loop to determine Euler theorem.)

Visual C下提取点阵字模源代码，可可直接生成C语言的code，可选字体，大小. (The dot matrix source code Visual C extract, cocoa directly generate C language code, selectable font, size.)

实现一个可编程表达式的计算器，并判断输入的表达式是否正确。(Expression of the realization of a programmable calculator, and determine the expression entered is correct.)

vs2005环境下编写的sbl病毒专杀工具，可以扫描文件中的sbl病毒，并集中清除(vs2005 environment prepared by the sbl virus Zhuanshagongju, you can scan documents in the sbl-virus, and focus on clear)
