Student-system

学生成绩管理系统，包括学号，成绩，性别，姓名等内容(Student performance management system, including school grades, gender, name, etc.)

一个学生信息管理的小系统，可以增加记录，查找记录，可以将数据导出到制定文件(student information management)

实现注册、登录、分老师账户和学生账户提供用户的成绩查询，修改等(To achieve registration, login, sub teacher and student accounts, accounts)

自己用VC++编写的操作Excel的程序，基于MFC，用于学生成绩的转换和计算，以及奖学金的评定。对于使用vc操作excel的朋友，可以直接使用或参考。(Own used VC++ codes for the Excel,basing on the MFC, using for the transfomaion and calculation of students grades, and the assessment of scholarship. To the friends who operate excel by vc++ codes,this can be used directly or by reference.)

语法分析器构造 借助于词法分析程序提供的分析结果，编写一个算符优先语法分析程序，程序能进行语法结构分析和错误检查并产生相应的归约信息。同时给出出错信息和错误类型，从而加深对语法分析的理解。 (parser using lexical analysis procedure for the analysis of results prepare a priority operator syntax analysis procedures, procedures for structural analysis and syntax error checking and produce corresponding reduction information. Also given wrong information and the wrong types, so as to enhance the understanding of syntax analysis.)

说明：  学生选课系统:采用C语言教程编写。适合初学者用户，文件内含有语法说明！(Student Course Selection System: The C language tutorial to prepare. Suitable for novice users, the file contains syntax description!)

这是2012年全国大学生数学建模大赛的题目，自己写的程序，纸张计数系统，非常实用。(This is the topic of 2012 national college students mathematical modeling contest, write their own procedures, paper counting system, very practical.)

批量生成学生信息的SQL语句，主要包括生成随机姓名的功能，如下： insert into name(name,age,sex,yuwen_score,shuxue_score)values(林洁凡,93,女,71,13) insert into name(name,age,sex,yuwen_score,shuxue_score)values(范贞晶,83,女,4,37) insert into name(name,age,sex,yuwen_score,shuxue_score)values(黎丹莉,10,女,96,28) insert into name(name,age,sex,yuwen_score,shuxue_score)values(康兰蓉,49,女,73,100) insert into name(name,age,sex,yuwen_score,shuxue_score)values(毕艳艳,62,女,57,42)(Batch SQL statements generated student information, including the name of the function to generate a random, as follows: insert into name (name, age, sex, yuwen_score, shuxue_score) values ​ ​ (Anna Fan, 93, female, 71,13) insert into name (name, age, sex, yuwen_score, shuxue_score) values ​ ​ (Fan Zhen Jing, 83, female, 4,37) insert into name (name, age, sex, yuwen_score, shuxue_score) values ​ ​ (Li Danli, 10, female, 96,28) insert into name (name, age, sex, yuwen_score, shuxue_score) values ​ ​ (Kanglan Rong, 49, female, 73,100) insert into name (name, age, sex, yuwen_score, shuxue_score) values ​ ​ (Bi Yanyan, 62, female, 57,42))

针对肖田元教授所著的《系统仿真导论》中龙格库塔法参考程序研究生很难看懂的现象，我加上了注释,使初学者能把学习算法和编写程序对应起来，从而可以有效地掌握算法的实现，对于用龙格库塔法进行在线实时仿真、建模、最优控制及自适应控制的教学有意义。(Professor Xiao Tianyuan for the book " Introduction to System Simulation," in reference to Runge-Kutta method is difficult to understand the phenomenon of post-graduate program, I have added comments to beginners can learn the corresponding algorithms and programming together, which could effectively implementation of control algorithms, using Runge-Kutta method for online real-time simulation, modeling, optimal control and adaptive control of a meaningful education.)

基于VC++和数据库的学生成绩管理 程序能运行 基本没什么错误
