c语言设计管理系统
1. 用c语言设计一个学生管理系统
高二的时候，我自己写过。现在在学其它的语言，就不献丑了，在网上给你找到了，是网络文库里面的，直接复制过来的话，排版不对，你自己去看一下吧，完整的代码。
名字就是《用C语言编写的一个学生信息管理系统》
PS：写这个，主要是用到C语言的链表，不难，只是有的时候，如果思路不清晰的话，容易写错，写漏等等，如果不参考上面，而是你自己写的话，建议先画个大概的树图出来，再开始编吧。
纯手工打的，帮到你的话，就采纳吧。
2. c语言 设计一个银行管理系统
功能：能够输入和查询客户存款取款记录。在客户文件中，每个客户是一条记录，包括编号、客户姓名、支取密码、客户地址、客户电话、账户总金额；在存取款文件中，每次存取款是一条记录，包括编号、日期、类别、存取数目、经办人。类别分为取款和存款两种。本系统能够输入客户存款或取款记录；根据客户姓名查询存款和取款记录。分步实施：1、初步完成总体设计，搭好框架，确定人机对话界面，确定函数个数；2、建立一个文件，输入客户的必要信息，能对文件进行显示、输入、修订、删除等。3、进一步要求：完成客户姓名查询存款和取款记录，并能得到每次帐户总金额。要求：1、用C语言实现系统；2、利用结构体数组实现信息的数据结构设计；3、系统的各个功能模块要求用函数的形式实现；4、界面友好（良好的人机交互），程序加必要的注释。课程设计实验报告要求：1、预习报告：题目、课程设计任务、数据结构、程序的总体设计（算法）、模块划分 。2、实验总结报告：流程图、主要源程序代码（需打印）、测试情况及调试中问题与解决方案、小结等要求：标明所用函数的用途和目的，简单叙述制作思路。
是否可以解决您的问题？

5. c语言设计学生信息管理系统
发消息给你了
6. C语言程序 如何编写管理系统
C语言编程的规则
C语言源程序的编程语法归纳如下:
1,强制性规则
1,一个C语言源程序必须有且只有一个MAIN函数.
2,函数名后必须紧跟圆括号对,函数体放在右圆括号")"后的花括号对"{}"中.
3,每个程序体(包括函数的函数体,含有多条语句的选择结构和循环结构中的语句序列)必须用一对花括号括起来.
4,文件包含预处理命令,#INCLUDE<*.H应置于源程序的开始位置.
5,语句未尾必须有分号,而预处理命令和函数首部的未尾及右花括号之后不要分号.
6,同一字母大,小写意义不同,关键字和标准库函数名必须用小写.
7,变量必须先定义,后使用
8,除已有明显间隔符外,标识符,关键字之间必须有至少一个空格9,注解必须包含在"/* */符号之间
