描述:每名老师带领五位同学,总共三名老师,设计学生和老师的结构体,在老师的结构体中,有老师和一个存放五名学生的数组作为成员,学生的成员有姓名、考试分数、创建数组存放三名老师,通过函数给每名老师以及所带的学生赋值,最终打印出老师数据以及老师所带的学生数据

//姓名
string sName;
//分数
int score;
};
struct Teacher
{
string tName;
struct Student sArray[5];

//给老师开始赋值

//通过循环给学生赋值

//打印所有信息

6.2通讯录管理系统功能:
添加联系人:向通讯录添加新人;
显示联系人:显示通讯录所有人的信息;
删除联系人:按照姓名删除指定联系人;
查找联系人:按照姓名查找制定联系人;
修改联系人:按照姓名重新修改指定联系人信息;
清空联系人:清空通讯录中的所有信息;
退出通讯录:退出当前使用的通讯录;
示例:
#includeusing namespace std;
#include#define MAX 1000
//联系人结构体
struct Person
{
string m_Name;
int m_Sex;
int m_Age;
string m_Phone;
string m_Addr;

//通讯录结构体
struct Addressbooks

struct Person personArray[MAX];//通讯录中保存的联系人数组
int m_Size;//通讯录中的人员个数
};
