C语言实现简单通讯录

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

头文件：
#include<stdlib.h>
#include<assert.h>
#include<string.h>
#define MAX 1000

typedef struct PEO
{
    char name[64];
    char sex[10];
    int age[100];
    char ph_num[12];
    char adder[128];
}peo, *peo_p, **peo_pp;
typedef  struct CONTACT
{
    peo person [MAX];
    int size;
}contact, *contact_p, **contact_pp;

int my_add(contact_p peoinf);
int my_delect(contact_p  peoinf);
int my_clear(contact_p  peoinf);
int my_search(contact_p  peoinf);
int my_modify(contact_p  peoinf);
void my_show(contact_p  peoinf);

#endif

测试函数：
