实现一个通讯录 通讯录可以动态存储个人的信息，每个人的信息包括： 姓名、性别、年龄、电话、住址
实现功能:
- 添加联系人信息
- 删除指定联系人信息
- 查找指定联系人信息
- 修改指定联系人信息
- 显示所有联系人信息
- 清空所有联系人
- 以名字排序所有联系人
- 保存联系人到文件
- 加载联系人
//8,9功能需要在对应的目录下创建对应的文件
代码如下:
#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
//功能

//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
//8. 保存联系人到文件
//9. 加载联系人
