简单的电子钟程序,用汇编语言编写，用单片机的三个接口(a simple electronic clock which can be used in c8051)

图书管理系统，分管理者和读者不同权限，可实现对书籍的管理，读者的管理等(Library management system, sub-managers and readers with different permissions)

想做高效的程序吗？mmx指令集，及常用c程序优化，等你来学(want efficient procedure? Mmx instruction set, and common procedures c optimization, you have to learn)

C语言是一种计算机程序设计语言,它既具有高级语言的特点,又具有汇编语言的特点。它的功能性非常强大,目前是各高校的一门必修课。并且市场上许多软件也是基于C语言的平台而产生的,所以C语言在大学中的教学也称得上是"不遗余力"。但是近些年很多的学生普遍反映C语言晦涩难懂,不容易学透,非常努力的学最后却得不能心满意足,课程过后一无所获,甚至一个小小的程序都写不出来,于是针对这些情况就做出一些初步的分析,并且从C语言编程技巧上提出相关的改善对策。 (C language is a computer programming language, both with advanced language features, but also has characteristics of assembly language. Its function is very powerful, is now a required course in colleges and universities. And also a lot of software on the market based on the C language, platform and produce, so C language teaching at the university is also described as a "spare no effort." But in recent years, a lot of students generally reflect the C language obscure, not easy to learn thoroughly, very hard to learn, but finally could not have satisfied the course after nothing, even a small program that can not write, so for these situations to to make some preliminary analysis, and from the C programming language skills relevant improvement measures put forward.)

说明：  逻辑电平接口设计规范逻辑电平接口设计规范(Logic level interface design specification Logic level interface design specification )

说明：  形参只是形式参数，并不参与实际运算，但是形参在同一个函数里要相同，实参是实际参数，参与实际的运算， 有几个形参就对应有几个实参，形参在自定义函数里，实参在主函数里 (Formals only formal parameter is not involved in the actual operation, but parameter in a function to be the same, the argument is the actual parameters involved in the actual operation, several shape parameters corresponding to several arguments, parameter in Custom function, the argument in the main function)

说明：  利用4个公共点解WGS84转北京54的7参数(The use of public four-point solution to WGS84 parameters Beijing 54 7)

光立方制作的源代码,可以直接输入进行编程,减少菜鸟编程实践 (Light cube made of the source code, you can directly enter the program, reducing the rookie programming practice)

用KEIL-C编写的交通灯源代码 对课程设计的朋友很有帮助的(KEIL-C prepared by the traffic lights at the source code of the Friend of the curriculum design helpful)

方差比检验代码，可以用来进行有效市场假说的检验，另外是一部分(Variance ratio test code can be used for the test of the efficient market hypothesis, the other is part of the)
