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 以下提供第一种方法: 1.静态实现: #define _CRT_SECURE_NO_WARNINGS 1 #ifndef __CONTACT_H__ #define __CONTACT_H__ #include <stdio.h> #include <string.h> enum OP { EXIT, ADD, DEL, MODIFY, SEARCH, DISPLAY, SORT, CLEAR }; #define NAME_MAX 20 #define SEX_MAX 5 #define TELE_MAX 12 #define ADDR_MAX 25 #define MAX 1000 typedef struct PerInfo { char name[NAME_MAX]; int age; char sex[SEX_MAX]; char tele[TELE_MAX]; char addr[ADDR_MAX]; }PeoInfo; typedef struct Contact { PeoInfo data[MAX]; int size; }Contact,*Pcon; void init_contact(Pcon pcon); void _add_contact(Pcon pcon); void _display_contact(Pcon pcon); void _del_contact(Pcon pcon); void _search_contact(Pcon pcon); void _modify_contact(Pcon pcon); void _sort_contact(Pcon pcon); void _clear_contact(Pcon pcon); #endif //__CONTACT_H__
函数实现部分:
