使用C语言打造通讯录管理系统和教学安排系统的代码示例

使用C语言打造通讯录管理系统和教学安排系统的代码示例这篇文章主要介绍了使用C语言打造通讯录管理系统和教学安排系统的代码示例,利用C语言强大的数组和指针能够更加清晰地体现设计思路,需要的朋友可以参考下:通讯录管理系统实现了通讯录的录入信息、保存信息、插入、删除、排序、查找、单个显示等功能。

C语言通讯录管理系统程序代码

C语言通讯录管理系统程序代码

一、课程设计题目及要求题目通讯录管理系统任务:自学C语言中相关知识,设计出通讯录管理系统。

要求如下所述:◆建立通讯录信息,信息至少包含编号、姓名、年龄、电话、通讯地址、电子邮箱等;;◆能够提供添加、删除和修改通讯录信息的功能;◆能够提供按姓名或电话等查询;◆将通讯录保存在文件中;◆能够按表格方式输出通讯录信息。

二、系统设计方案(一)总体框架图:通讯录管理系统:1、录入通讯录信息2、修改通讯录信息3、查询通讯录信息4、浏览通讯录信息5、增加通讯录信息6、推出系通讯录统(二)模块设计模块一:头文件,变量定义,函数的声明对系统所使用的变量进行定义,对函数进行声明模块二:录入通讯录信息声明函数void readfile(),说明一个文件指针FILE *fp 打开文件"student.txt"模块三:通讯录信息的查找声明void seek()为查找函数,通过switch(item)设定用学号查找,用姓名查找两个分支模块四:通讯录信息的修改声明void modify()为学生信息修改函数,通过switch(item)设定所要修改的项目模块五:通讯录信息按学号排序声明void sort()将录入通讯录信息系按升序排列,用的是“冒泡排序法”实现排序模块六:加通讯录信息声明void insert()插入通讯录信息,先通过判断通讯录是否存在,若否则继续输入,若是跳出,重新循环模块七:通讯录信息声明void del()实现通讯录信息删除,通过学号对比确定要删除的信息,然后用后一个替换掉。

模块八:示学生信息通过display()函数输出通讯录信息模块九;存信息通过fp=fopen("student.txt","w");写入信息模块十:界面菜单通过switch(num)调用,以上各函数,实现功能三、设计详情1.主函数主函数设计要求简洁,只提供部分提示语和函数的调用【程序】图1. 主函数流程图void menu()/* 界面 */{ int num;printf(" \n\n 自动化0901通讯录管理系统 \n\n");printf(" ***************** \n\n");printf(" * 制作人:翁行兴 * \n \n");printf(" ***************** \n\n");printf("*********************系统功能菜单************************ \n");printf(" ---------------------- ---------------------- \n");printf(" * 1.刷新学生信息 * * 2.查询学生信息 * \n");printf(" * 3.修改学生信息 * * 4.增加学生信息 * \n");printf(" * 5.按学号删除信息 * * 6.显示当前信息 * \n");printf(" * 7.保存当前学生信息 * * 8.退出系统 * \n");printf(" ---------------------- ---------------------- \n");printf("请选择菜单编号:");scanf("%d",&num);switch(num){case 1:readfile();break;case 2:seek();break;case 3:modify();break;case 4:insert();break;case 5:del();break;case 6:display();break;case 7:save();break;case 8:k=0;break;default:printf("请在1-8之间选择\n");}}四、源代码#include<stdio.h>#include<stdlib.h>#include<string.h>#define BUFLEN 100#define LEN 15#define N 100struct record /*结构体*/{char code[LEN+1]; /* 学号 */char name[LEN+1]; /* 姓名 */int age; /* 年龄 */char sex[3]; /* 性别 */char time[LEN+1]; /* 出生年月 */char add[30]; /* 家庭地址 */char tel[LEN+1]; /* 电话号码 */char mail[30]; /* 电子邮件地址 */ }stu[N];int k=1,n,m; /* 定义全局变量 */ void readfile();/* 函数声明 */void seek();void modify();void insert();void del();void display();void save();void menu();int main(){while(k)menu();system("pause");return 0;}void readfile()/* 建立信息 */{char *p="student.txt";FILE *fp;int i=0;if ((fp=fopen("student.txt","r"))==NULL){printf("Open file %s error!

一、课程设计题目及要求题目通讯录管理系统任务:自学C语言中相关知识,设计出通讯录管理系统。

要求如下所述:◆建立通讯录信息,信息至少包含编号、、年龄、、通讯地址、电子等;;◆能够提供添加、删除和修改通讯录信息的功能;◆能够提供按或等查询;◆将通讯录保存在文件中;◆能够按表格方式输出通讯录信息。

二、系统设计方案(一)总体框架图:通讯录管理系统:1、录入通讯录信息2、修改通讯录信息3、查询通讯录信息4、浏览通讯录信息5、增加通讯录信息6、推出系通讯录统(二)模块设计模块一:头文件,变量定义,函数的声明对系统所使用的变量进行定义,对函数进行声明模块二:录入通讯录信息声明函数void readfile(),说明一个文件指针FILE *fp 打开文件"student.txt"模块三:通讯录信息的查找声明void seek()为查找函数,通过switch(item)设定用学号查找,用查找两个分支模块四:通讯录信息的修改声明void modify()为学生信息修改函数,通过switch(item)设定所要修改的项目模块五:通讯录信息按学号排序声明void sort()将录入通讯录信息系按升序排列,用的是“冒泡排序法”实现排序模块六:加通讯录信息声明void insert()插入通讯录信息,先通过判断通讯录是否存在,若否则继续输入,若是跳出,重新循环模块七:通讯录信息声明void del()实现通讯录信息删除,通过学号对比确定要删除的信息,然后用后一个替换掉。

模块八:示学生信息通过display()函数输出通讯录信息模块九;存信息通过fp=fopen("student.txt","w");写入信息模块十:界面菜单通过switch(num)调用,以上各函数,实现功能三、设计详情1.主函数主函数设计要求简洁,只提供部分提示语和函数的调用图1. 主函数流程图void menu()/* 界面 */{ int num;printf(" \n\n 自动化0901通讯录管理系统 \n\n");printf(" ***************** \n\n");printf(" * 制作人:翁行兴 * \n \n");printf(" ***************** \n\n");printf("*********************系统功能菜单************************ \n");printf(" ---------------------- ---------------------- \n");printf(" * 1.刷新学生信息 * * 2.查询学生信息 * \n");printf(" * 3.修改学生信息 * * 4.增加学生信息 * \n");printf(" * 5.按学号删除信息 * * 6.显示当前信息 * \n");printf(" * 7.保存当前学生信息 * * 8.退出系统 * \n");printf(" ---------------------- ---------------------- \n");printf("请选择菜单编号:");scanf("%d",&num);switch(num){case 1:readfile();break;case 2:seek();break;case 3:modify();break;case 4:insert();break;case 5:del();break;case 6:display();break;case 7:save();break;case 8:k=0;break;default:printf("请在1-8之间选择\n");}}四、源代码#include<stdio.h>#include<stdlib.h>#include<string.h>#define BUFLEN 100#define LEN 15#define N 100struct record /*结构体*/{char code[LEN+1]; /* 学号 */char name[LEN+1]; /* */int age; /* 年龄 */char sex[3]; /* 性别 */char time[LEN+1]; /* 出生年月 */ char add[30]; /* 家庭地址 */char tel[LEN+1]; /* */char mail[30]; /* 电子地址 */}stu[N];int k=1,n,m; /* 定义全局变量 */ void readfile();/* 函数声明 */void seek();void modify();void insert();void del();void display();void save();void menu();int main(){while(k)menu();system("pause");return 0;}void readfile()/* 建立信息 */{char *p="student.txt";FILE *fp;int i=0;if ((fp=fopen("student.txt","r"))==NULL){printf("Open file %s error!
