der increasing pressure. As is known to all, buses have a very large role in every city, and almost every citizen should use the bus. And the bus routes are often changed. How to effectively strengthen the maintenance and management of the operation line becomes the urgent problem of the bus system.
Therefore, it is very important to design a bus line management system based on C language. Based on C language, this paper designs a bus line management system based on Visual C++. This system provides the bus company to handle the daily business functions. Efficient management functions are provided on site Settings and line Settings. Mainly from the site and the line management. Including reveal all bus stops, add, bus stops, modify, bus stops, reveal all bus lines, adding bus lines, adjust the bus lines and query function such as bus lines, beautiful interface, easy to use. If the system is used, the bus company can modify and save the route information in a timely manner, so as to satisfy the citizens enquiries and facilitate the life of the people. And the system is easy to use. The user can query the required information simply by selecting and entering the displayed prompt information. Improve travel efficiency. Based on our knowledge, scope and depth, a simple management inquiry system is established here.
Key words: C language, bus line management, flow chart, module decomposition, document.
一、绪论
C语言
未装任何软件的计算机称为“裸机”。只有装有操作系统和应用软件的计算机才能正常工作。操作系统和应用软件均是用计算机语言编成的。C语言是计算机语言,在国际上广泛流行。
早期的C语言主要是用于UNIX系统。八十年代,C语言在其它各种计算机的操作系统中广泛应用成为最优秀程序设计语言之一。
C语言对比汇编语言的好处简单来说进行了抽象,具有如下优点:
1.C语言开发的效率高。
2.C语言与人类思维习惯相符。
3.模块化。
4.C语言编写的程序可读性和可维护性强。
当然C语言也存在一些缺点,比如实时性通常要比汇编差。
无论哪一种程序设计语言,它都具有规定的表达方法。无论哪一种程序设计语言,也都有特定的语法。无论用哪一种程序设计语言编写程序,都要严格遵守编程语言的语法规定,并且按照表达方式编写。才能保证编写的程序在计算机中能正确地被执行、阅读和理解。
本论文要设计一个基于C语言的公交线路管理系统。因此开发一个C程序要完成以下步骤:
1上机输入和编辑源程序也就是程序设计。
2编译源程序即编译。
3对程序进行链接处理即链接。
4运行可执行程序,得到执行结果即运行。
课题的研究意义
城市建设规模逐渐扩大,公交系统承受的压力也越来越大,我们都知道,公交车在每一个城市中都发挥着巨大的作用,几乎每个市民出行都需要使用公交车作为交通工具。但是公交车的路线经常会有所改动。给公交公司管理公交系统增加了很多麻烦。也不利于市民查询出行线路。
