一、Contact.h文件
包含函数的声明
#pragma once
#define _CRT_SECURE_NO_WARNINGS 1
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <assert.h>
#define MAX 100
#define MAX_NAME 20
#define MAX_SEX 10
#define MAX_TELE 20
#define MAX_ADDR 30
#define MAX_LEG 5
//结构体的定义，用于储存通讯录数据
struct Contact
{
char name[MAX_NAME];
char sex[MAX_SEX];
char tele[MAX_TELE];
char addr[MAX_ADDR];
int age;
};
struct PeoInfo
{
struct Contact* data;
int length;
int capacity;
};
//定义游戏菜单函数
void menu();
//定义初始结构体函数
void InitContact(struct PeoInfo* abs);
//添加通讯录消息函数的声明
void AddConInfo(struct PeoInfo* abs);
//查询信息是否存在函数
int IsExist(struct PeoInfo* abs, char* name);
//删除指定信息函数的定义
void DelConInfo(struct PeoInfo* abs);
//修改指定信息函数的定义
void ModefiInfo(struct PeoInfo* abs);
//查询指定信息函数的定义
void SearchInfo(struct PeoInfo* abs);
//展示通讯录信息函数的定义
void ShowInfo(struct PeoInfo* abs);
//清空通讯录列表函数的定义
void ClearInfo(struct PeoInfo* abs);
//排序通讯录信息函数的定义
void SortInfo(struct PeoInfo* abs);
//扩容函数的定义
int IncMemmery(struct PeoInfo* abs);
//释放内存函数的定义

//保存通讯录函数的定义
void saveInfo(struct PeoInfo* abs);
//加载通讯录函数的定义
void loadInfo(struct PeoInfo* abs);

}
else
{
printf("%-20s\t%-10s\t%-20s\t%-20s\t%-10s\n","姓名","性别","联系方式","住址","年龄");
printf("%-20s\t%-10s\t%-20s\t%-20s\t%-10d\n",

}
}
//清空通讯录列表函数的实现
void ClearInfo(struct PeoInfo* abs)
{
assert(abs);
struct Contact* ptr = (struct Contact*)realloc(abs->data, MAX_LEG * (sizeof(struct Contact)));
if (ptr == NULL)
{

}
else

}
}
//排序通讯录函数的实现
int CmpByAge(const void* e1, const void* e2)
{
return ((struct Contact*)e1)->age - ((struct Contact*)e2)->age;
}
int CmpByName(const void* e1, const void* e2)

qsort(abs->data, abs->length, sizeof(struct Contact), CmpByAge);
printf("已按照年龄排序成功！\n");
}
else if(ch == 'N')

{
fwrite(abs->data + i, sizeof(struct Contact), 1, pf);
}

}
三、test.c文件
包含主函数即代码思想
#include "contact.h";
int main()
{
int input = 0;
struct PeoInfo con;
//初始化结构体
InitContact(&con);
do
{
menu();
printf("请选择：>");
scanf("%d", &input);
switch (input)
{
case 1:
AddConInfo(&con);
break;
case 2:
DelConInfo(&con);
break;
case 3:
ModefiInfo(&con);
break;
case 4:
SearchInfo(&con);
break;
case 5:
ShowInfo(&con);
break;
case 6:
ClearInfo(&con);
break;
case 7:
SortInfo(&con);
break;
case 0:
saveInfo(&con);
FreeInfo(&con);
printf("退出通讯录！");
break;
default:
printf("选择错误！\n");
}
} while (input);
return 0;
}
