使用C++实现通讯录管理系统，包含如下功能：添加联系人、显示联系人、删除联系人、查找联系人、修改联系人、清空联系人。 相关代码如下：
#include<iostream> #include<string> using namespace std; #define MAX 100 struct Person { string m_Name; //姓名 string m_Sex; //性别 int m_Age; //年龄 string m_Phone; //手机号码 string m_Addr; //家庭住址 }; struct Address_book { struct Person personArray[MAX]; //通讯录中联系人的数组 int m_size; //通讯录的大小 }; void showMenu(); void AddPerson(struct Address_book* abs); void showPerson(Address_book* abs); void deletePerson(Address_book* abs); void searchPerson(Address_book* abs); void modifyPerson(Address_book* abs); void clearPerson(Address_book* abs); int find_Person(Address_book* abs, string find_name); int main(void) { Address_book abs; //创建通讯录 abs.m_size = 0; int select = 0; //定义用户输入变量 while (true) { showMenu(); cin >> select; switch (select) { case 1: //添加联系热 AddPerson(&abs); break; case 2: //显示联系人 showPerson(&abs); break; case 3: //删除联系人 deletePerson(&abs); break; case 4: //查找联系人 searchPerson(&abs); break; case 5: //修改联系人 modifyPerson(&abs); break; case 6: //清空联系人 clearPerson(&abs); break; case 0: //退出通讯录 cout << "欢迎下次使用！" << endl; return 0; break; default: break; } } system("pause"); return 0; } //菜单界面 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.退出通信录 " << "*****" << endl; cout << "**************************" << endl; } //添加联系人 void AddPerson(struct Address_book* abs) { if (abs->m_size >= 100) { cout << "通讯录已满，无法添加！" << endl; return; } else { //姓名 cout << "请输入联系人姓名：" << endl; string name; cin >> name; abs->personArray[abs->m_size].m_Name = name; //性别 cout << "请输入联系人性别：" << endl; string sex; cin >> sex; abs->personArray[abs->m_size].m_Sex = sex; //年龄 cout << "请输入联系人年龄：" << endl; int age; cin >> age; abs->personArray[abs->m_size].m_Age = age; //号码 cout << "请输入联系人的手机号码：" << endl; string phone; cin >> phone; abs->personArray[abs->m_size].m_Phone = phone; //住址 cout << "请输入联系人的住址：" << endl; string address; cin >> address; abs->personArray[abs->m_size].m_Addr = address; abs->m_size++; //表长增加 cout << "添加成功！" << endl; system("pause"); //按任意键继续 system("cls"); //清屏 } } //显示联系人 void showPerson(Address_book* abs) { if (abs->m_size == 0) { cout << "记录为空，请输入联系人信息！" << endl; } else { for (int i = 0; i < abs->m_size; i++) { cout << "姓名：" << abs->personArray[i].m_Name << "\t"; cout << "性别：" << abs->personArray[i].m_Sex << "\t"; cout << "年龄：" << abs->personArray[i].m_Age << "\t"; cout << "手机号码：" << abs->personArray[i].m_Phone << "\t"; cout << "住址：" << abs->personArray[i].m_Addr << endl; } } system("pause"); system("cls"); } //删除联系人 void deletePerson(Address_book* abs) { string find_name; int flag; //接收find_Person的返回值 cout << "请输入要删除的联系人姓名：" << endl; cin >> find_name; flag = find_Person(abs, find_name); if (flag == -1) { cout << "未查询到该用户的信息！" << endl; } else { for (int i = flag; 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"); } //查找联系人 void searchPerson(Address_book* abs) { string search_name; int flag1; cout << "请输入要查找的联系人的姓名：" << endl; cin >> search_name; flag1 = find_Person(abs, search_name); if (flag1 == -1) { cout << "查找失败！无此联系人。" << endl; } else { cout << "查询成功！结果如下：" << endl; cout << "姓名：" << abs->personArray[flag1].m_Name << "\t"; cout << "性别：" << abs->personArray[flag1].m_Sex << "\t"; cout << "年龄：" << abs->personArray[flag1].m_Age << "\t"; cout << "手机号码：" << abs->personArray[flag1].m_Phone << "\t"; cout << "住址：" << abs->personArray[flag1].m_Addr << endl; } system("pause"); system("cls"); } //修改联系人 void modifyPerson(Address_book* abs) { string modify_name; cout << "请输入要修改的联系人的姓名：" << endl; cin >> modify_name; int flag2 = find_Person(abs, modify_name); if (flag2 == -1) { cout << "该用户不存在！" << endl; } else { //姓名 cout << "请输入联系人姓名：" << endl; string name; cin >> name; abs->personArray[flag2].m_Name = name; //性别 cout << "请输入联系人性别：" << endl; string sex; cin >> sex; abs->personArray[flag2].m_Sex = sex; //年龄 cout << "请输入联系人年龄：" << endl; int age; cin >> age; abs->personArray[flag2].m_Age = age; //号码 cout << "请输入联系人的手机号码：" << endl; string phone; cin >> phone; abs->personArray[flag2].m_Phone = phone; //住址 cout << "请输入联系人的住址：" << endl; string address; cin >> address; abs->personArray[flag2].m_Addr = address; } cout << "修改成功！" << endl; system("pause"); system("cls"); } //清空联系人 void clearPerson(Address_book* abs) { abs->m_size = 0; cout << "通讯录已清空！" << endl; system("pause"); system("cls"); } //查找联系人 int find_Person(Address_book* abs, string find_name) { for (int i = 0; i < abs->m_size; i++) { if (abs->personArray[i].m_Name == find_name) { return i; //返回元素在数组中的位置 } } return -1; }
