C++实现通讯录管理系统项目
本文实例为大家分享了C++实现通讯录管理系统的具体代码,供大家参考,具体内容如下
1、通讯录设计要点
1:添加联系人:向通讯录中添加新人(包括:性别,年龄,联系电话,家庭住址),并且最多记录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:按照姓名进行删除指定联系人
4:查找联系人:按照姓名查找联系人
5:修改联系人:按照姓名修改联系人
6:清空联系人:按照姓名清空联系人
7:退出通讯录:退出当前使用的通讯录
2、设计思路
/** 本教程主要利用C++来实现一个通讯管理系统,系统中需要实现如下功能: 1:添加联系人:向通讯录中添加新人(包括:性别,年龄,联系电话,家庭住址),并且最多记录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:按照姓名进行删除指定联系人 4:查找联系人:按照姓名查找联系人 5:修改联系人:按照姓名修改联系人 6:清空联系人:按照姓名清空联系人 7:退出通讯录:退出当前使用的通讯录 */ // 引入C++标准包 #include <iostream> #include <string> // #define MAX_NUMBER 2 using namespace std; // const int MAX_NUMBER2 = 3; // 定义常量通讯录最大值 (auto 让编译其自己推断变量的类型) constexpr auto MAX = 3; // 定义联系人结构体 struct Person { string name; int sex; int age; string phoneNamer; string address; }; struct addressbook { struct Person perArray[MAX]; // struct Person personArr[MAX_NUMBER2]; // struct Person personArr[MAX_NUMBER]; int person_size; }; // 展示通讯录系统 void showMenu() { cout << "欢迎来到通讯录管理系统" << endl; cout << "功能1:添加联系人" << endl; cout << "功能2:显示联系人" << endl; cout << "功能3:删除联系人" << endl; cout << "功能4:查找联系人" << endl; cout << "功能5:修改联系人" << endl; cout << "功能6:清空联系人" << endl; cout << "功能0:退出通讯录系统" << endl; } int isExist(addressbook* personBook , string name) { for (int i = 0; i < personBook->person_size;i++) { if (personBook->perArray[i].name == name) { // 从通讯录中找到了某个人 return i; } } return -1; } void addPerson(addressbook *addBook) { if (addBook->person_size < MAX) { cout << "请输入姓名:" << endl;

} else { cout << "查无此人喔!" << endl; } system("pause"); system("cls"); } void modifyPerson(addressbook *person) { string modifyName; cout << "请输入修改后的姓名: " << endl; cin >> modifyName; int exist = isExist(person, modifyName); if (exist != -1) { person->perArray[exist].name = modifyName; while (true) { int modifySex; cout << "请输入修改后的性别: (1:男 2:女) " << endl; cin >> modifySex; if (modifySex == 1 || modifySex ==2) { person->perArray[exist].sex = modifySex; break; } else { cout << "您应当输入1或者2,请重新输入" << endl; } } int modifyAge; cout << "请输入修改后的年龄: "; cin >> modifyAge; person->perArray[exist].age = modifyAge; string modifyPhoneNum; cout << "请输入修改后的电话: "; cin >> modifyPhoneNum;

} system("pause"); system("cls"); } // 清空通讯录 void clearPersonAddress(addressbook *personBook) { string ensure; cout << "您确定要是清空所有联系人信息吗?注意此操作不可逆,请谨慎操作,请输入\"我同意\" " << endl; cin >> ensure; if (ensure == "我同意") { personBook->person_size = 0; for (int i = 0; i < personBook->person_size; i++) { personBook->perArray[i].address = ""; personBook->perArray[i].name = ""; personBook->perArray[i].phoneNamer = ""; personBook->perArray[i].age =0; personBook->perArray[i].sex =0; } cout << "已成功清空通讯录列表" << endl; } else { cout << "撤销清空联系人列表" << endl; } system("pause"); system("cls"); } int main() { std::cout << "通许录管理系统 \n"; struct addressbook address; address.person_size = 0; int userSelect = -1; while (true) { showMenu(); cout << "请在下方输入您向选择的功能(输入下面数字即可)" << endl; cin >> userSelect; switch (userSelect) { case 1: addPerson(&address); break; case 2: showPerson(address); break; case 3: deletePerson(&address); break; case 4: findPerson(&address); break; case 5: modifyPerson(&address); break; case 6: clearPersonAddress(&address); break; case 0: cout << "退出系统成功,欢迎您下次使用!" << endl; return 0; default: system("pause"); break; } } }
