简单的静态通讯录的实现。

实现一个通讯录:

通讯录可以用来存储1000个人的信息，每个人的信息包括：姓名、性别、年龄、电话、住址

提供方法：
1. 添加联系人信息
2. 删除指定联系人信息
3. 查找指定联系人信息
4. 修改指定联系人信息
5. 显示所有联系人信息
6. 清空所有联系人
7. 以名字排序所有联系人

 为了结构清晰我使用了三个文件来进行封装，Contact.h封装结构体以及函数的声明,test.c封装主函数，Contact.c用来封装函数的算法。

contact.h

#ifndef __CONTACT_H__ #define __CONTACT_H__ #include <stdio.h>#include <stdlib.h>//#include <iostream>#include<string.h>#define MAX 1000 #define NAME_MAX 20 #define SEX_MAX 5 #define ADDR_MAX 30 #define TELE_MAX 12 typedef struct PeoInfo{char name[NAME_MAX];int age;char sex[SEX_MAX];char addr[ADDR_MAX];char tele[TELE_MAX];}PeoInfo;typedef struct Contact{PeoInfo data[MAX];int sz;}Contact, *pContact;void InitContact(pContact pcon);void AddContact(pContact pcon);void ShowContact(const pContact pcon);void DelContact(pContact pcon);void SearchContact(pContact pcon);void ModifyContact(pContact pcon);void SortContach(pContact pcon);void ClearContact(pContact pcon);#endif

contact.c

test.c

#define _CRT_SECURE_NO_WARNINGS 1#include"contact.h"void menu(){printf("\t********** 通讯录管理 **********\n");printf("\t*** 1.添加联系人 2.查找联系人***\n");printf("\t*** 3.删除联系人 4.修改联系人***\n");printf("\t*** 5.清空联系人 6.显示联系人***\n");printf("\t*** 7.按姓名排序 0.退出系统  ***\n");printf("\t**********  请选择:  ***********\n");}int main(){Contact con;InitContact(&con);int input = 0;do{menu();printf("请选择：");scanf("%d", &input);switch (input){case 1:AddContact(&con);break;case 2:SearchContact(&con);break;case 3:DelContact(&con);break;case 4:ModifyContact(&con);break;case 5:ClearContact(&con);break;case 6:ShowContact(&con);break;case 7:SortContach(&con);break;case 0:exit(EXIT_FAILURE);default:break;}} while (input != 0);system("pause");return 0;}

总结：在这个程序的实现过程中，程序出现了许多问题，特别是传参过程中和函数的实现过程中，参数稍有差错，程序就会出现问题，导致运行不成功。
