1. 功能分析与实现步骤

需要的功能：
   1.添加联系人：姓名，性别，年龄，联系电话，家庭住址（最多纪录1000人）
   2.显示联系人：显示通讯录中所有联系人信息
   3.删除联系人：按照姓名删除指定联系人
   4.查找联系人：按照姓名查看指定联系人信息
   5.修改联系人：按照姓名重新修改指定联系人
   6.清空联系人：清空通讯录中所有信息
   7.退出通讯录

步骤：
   1.菜单页面的制作
   2.对按键的判断
       2.1 退出的设计
       2.2 添加联系人
               设计联系人结构体
               设计通讯录结构体
               main函数中创建通讯录
               封装添加联系人函数
               测试添加联系人功能
       2.3 显示联系人
       2.4 删除联系人
               需要先实现找到指定联系人的功能
       2.5 查找联系人
       2.6 修改联系人
       2.7 清空通讯录
               删除所有联系人信息，只需要将通讯的联系人数量置为0，做逻辑清空即可

2. 代码编写

2.1 联系人和通讯录结构体设计

// 设计联系人结构体
struct Person
{// 姓名string m_Name;// 性别  1:男  2:女int m_sex;// 年龄int m_age;// 电话string m_Phone;// 住址string m_Addr;
};struct Addressbooks
{// 通讯录中保存的联系人数组struct Person personArray[MAX];// 通讯录中当前记录联系人个数int m_size;
};

2.2 通讯录页面

// 1.菜单页面
void showMenu()
{cout << "*****************************" << endl;cout << "*****     1:添加联系人    *****" << endl;cout << "*****  2:显示联系人    *****" << endl;cout << "*****  3:删除联系人    *****" << endl;cout << "*****  4:查找联系人    *****" << endl;cout << "*****  5:修改联系人    *****" << endl;cout << "*****  6:清空联系人    *****" << endl;cout << "*****  0:退出通讯录    *****" << endl;cout << "*****************************" << endl;
}

2.3 添加联系人

// 2.添加联系人
void addPerson(Addressbooks* abs)
{// 判断通讯录是否已满if (abs->m_size == MAX){cout << "通讯录已满，无法添加" << endl;return;}else{// 姓名string name;cout << "请输入姓名：" << endl;cin >> name;abs->personArray[abs->m_size].m_Name = name;// 性别cout << "请输入性别（1:男  2:女）：" << endl;int sex = 0;while (true){cin >> sex;if (sex == 1 || sex == 2){abs->personArray[abs->m_size].m_sex = sex;break;}cout << "输入有误，请重新输入" << endl;}// 年龄int age;cout << "请输入年龄：" << endl;while (true){cin >> age;if (age >= 0 && age <= 120){abs->personArray[abs->m_size].m_age = age;break;}cout << "输入有误，请重新输入" << endl;}// 电话string phone;cout << "请输入电话：" << endl;cin >> phone;abs->personArray[abs->m_size].m_Phone = phone;// 地址string address;cout << "请输入地址：" << endl;cin >> address;abs->personArray[abs->m_size].m_Addr = address;// 更新通讯录人数abs->m_size++;cout << "添加成功" << endl;system("pause");   // 按下任意键继续system("cls");      // 清屏}
}

2.4 显示所有联系人

// 显示联系人
void showPerson(Addressbooks* abs)
{// 判断通讯录中人数是否为0if (abs->m_size == 0){cout << "通讯录为空" << endl;return;}else{for (int i = 0; i < abs->m_size; i++){cout << "姓名：" << abs->personArray[i].m_Name << "\t";cout << "性别(1:男  2:女)：" << (abs->personArray[i].m_sex == 1 ? "男" : "女") << "\t";cout << "年龄：" << abs->personArray[i].m_age << "\t";cout << "电话：" << abs->personArray[i].m_Phone << "\t";cout << "地址" << abs->personArray[i].m_Addr << endl;}}system("pause");system("cls");

2.5 检测联系人

删除和查找指定联系人都需要一个检测联系人是否存在的模块

// 检测联系人是否存在，存在返回编号，不存在返回-1
int isExit(Addressbooks* abs, string name)
{for (int i = 0; i < abs->m_size; i++){if (abs->personArray[i].m_Name == name){return i;}}return -1;
}

2.6 删除指定联系人

// 删除指定联系人
void deletePerson(Addressbooks* abs)
{cout << "请输入删除联系人姓名：" << endl;string name;cin >> name;int judge;judge = isExit(abs, name);if(judge == -1){cout << "查无此人" << endl;}else{// 数据前移for (int i = judge; i < abs->m_size; i++){abs->personArray[i] = abs->personArray[i + 1];}abs->m_size--;cout << "删除成功" << endl;}system("pause");system("cls");
}

2.7 查找指定联系人

// 查找指定联系人
void findPerson(Addressbooks* abs)
{cout << "请输入查找的联系人姓名：" << endl;string name;cin >> name;int judge;judge = isExit(abs, name);if (judge == -1){cout << "查无此人" << endl;}else{cout << "姓名：" << abs->personArray[judge].m_Name << endl;cout << "性别(1:男  2:女)：" << (abs->personArray[judge].m_sex == 1 ? "男" : "女") << endl;cout << "年龄：" << abs->personArray[judge].m_age << endl;cout << "电话：" << abs->personArray[judge].m_Phone << endl;cout << "地址" << abs->personArray[judge].m_Addr << endl;}system("pause");system("cls");
}

2.8 更改指定联系人

// 更改指定联系人
void modifyPerson(Addressbooks* abs)
{cout << "请输入更改的联系人姓名：" << endl;string name;cin >> name;int judge;judge = isExit(abs, name);if (judge == -1){cout << "查无此人" << endl;}else{while (true){cout << "姓名：" << abs->personArray[judge].m_Name << endl;cout << "性别(1:男  2:女)：" << (abs->personArray[judge].m_sex == 1 ? "男" : "女") << endl;cout << "年龄：" << abs->personArray[judge].m_age << endl;cout << "电话：" << abs->personArray[judge].m_Phone << endl;cout << "地址" << abs->personArray[judge].m_Addr << "\n" << endl;cout << "请输入要修改的内容\n1:姓名\t2:性别\t3:年龄\t4:电话\t5:地址\t0:退出" << endl;int rev;cin >> rev;switch (rev){case 1:{cout << "请输入更改后的姓名" << endl;string new_name;cin >> new_name;abs->personArray[judge].m_Name = new_name;break;}case 2:{cout << "请输入更改后的性别" << endl;int new_sex;while (true){cin >> new_sex;if (new_sex == 1 || new_sex == 2){abs->personArray[judge].m_sex = new_sex;break;}cout << "输入有误，请重新输入" << endl;}break;}case 3:{int new_age;cout << "请输入更改后的年龄：" << endl;while (true){cin >> new_age;if (new_age >= 0 && new_age <= 120){abs->personArray[judge].m_age = new_age;break;}cout << "输入有误，请重新输入" << endl;}break;}case 4:{string new_phone;cout << "请输入更改后的电话：" << endl;cin >> new_phone;abs->personArray[judge].m_Phone = new_phone;break;}case 5:{// 地址string new_address;cout << "请输入地址：" << endl;cin >> new_address;abs->personArray[judge].m_Addr = new_address;break;}case 0:{cout << "修改完成" << endl;system("pause");system("cls");return;}default:break;}system("pause");system("cls");}}
}

2.9 清空所有联系人

// 清空所有联系人
void cleanPerson(Addressbooks* abs)
{cout << "是否确认清空，确认请按1，返回请按0" << endl;int nub;cin >> nub;while (true){if (nub == 1){abs->m_size = 0;cout << "所有联系人已清空" << endl;system("pause");system("cls");return;}else if (nub == 0){cout << "返回主菜单" << endl;system("pause");system("cls");return;}else{cout << "请重新输入，确认请按1，返回请按0" << endl;cin >> nub;}}
}
