工程学院国脉信息学院《C语言程序设计》课程设计实验报告题目：城区古树名木信息管理系统专业：电子信息工程班级：（1）班学号：姓名：成绩：指导教师：完成日期：2011年 4 月 20 日四、系统结构图五、功能模块说明古树名木信息的录入、查询、修改、删除模块如下：1）、列表模块2）、录入模块3）查询模块4).*城区信息模块与古树名木养护信息的录入、查询、删除模块雷同。

六、运行情况1）、主菜单N开始读文件数据列出数据输入stree[i].number==s ?删除数据 Y 返回主函数 返回主函数输出数据 开始读文件数据输入numTree[i].numbe ==rnum ? 输出数据 返回主函数YN显示数据 修改数据 返回主函数一、课程设计目的1）对C各部分知识的综合应用能力2）提高程序设计的能力3）提升对于较大程序的抽象分析设计能力4）学习调试和测试的技巧二、课程设计内容1）熟悉C实验环境，按给定的上机步骤练习完成；2）熟悉C程序的编辑，编译，链接和运行的过程。

3）编译一个应用系统程序，形成一个软件系统。

三、数据结构设计及用法说明1、本程序使用到了三个struct，分别是（1）struct tree/*古树名木养护信息*/{ char number[5];/*编号*/char area[10];/*区号*/char name[100];/*树名*/char xueming[100];/*学名*/char branch[100];/*科属*/int age;/*树龄*/char day[11];/*确认时间*/int rank;/*保护级别*/char place[100];/*栽植地点*/}tree[MAX];（2）struct city/*城区信息*/{ char cityarea[7];/*区号*/char areaname[20];/*区名*/char management[30];/*主管部门*/char address[30];/*地址*/char tel[13];/*电话*/char worker[20];/*负责人*/}city[MAX];（3）struct protection/*古树名木养护信息*/{ char cityareas[7];/*区号*/char treenumber[5];/*古树名木编号*/char protecter[30];/*养护人*/char data[11];/*养护日期*/char measure[30];/*养护措施*/char state[20];/*生长状况*/}pro[MAX];2、本段程序在main函数中嵌套了所有子函数，包括“void Input();/* 古树基本信息录入*/”、“void Display();/*古树信息浏览*/、“void Find();/*古树信息查询*/”、“void Modify();/*删除*/”、“void Change();/*修改*/”、“void Inputcity();/* 城区信息录入*/”、“void Displaycity();/* 城区信息浏览*/”、“void Changecity();/* 城区信息修改*/”、“void Inputprotection();/* 养护信息录入*/”、“void Displayprotection();/* 养护信息浏览*/”、“void Changeprotection()/*修改*/”。

2）录入古树名木信息3）浏览古树名木信息4）查询古树名木信息（按古树名查找）（按编号查找）5）删除古树信息（删除后的信息浏览）6）录入城区信息6）城区信息浏览7）从城区信息中查询某城区的古树名木8）从城区信息中删除某古树名木9）录入古树名木养护信息10）浏览古树名木养护信息11）修改古树名木养护信息（修改后的古树名木养护信息浏览）12）退出系统七、设计体会和反思#include<stdio.h>#include<string.h>#include<stdlib.h>#include<conio.h>#define
