C++实现通讯录管理系统项目
作者:hongwen_yul
这篇文章主要为大家详细介绍了C++实现通讯录管理系统项目,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
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; string name; cin >> name; // addBook 操作指针指向的哪个对象 addBook->perArray[addBook->person_size].name = name; cout << "请输入性别对应的序号:1--男 2---女" << endl; int sex; // 通过while死循环持续性的读取用户输入的性别 while(true) { cin >> sex;

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;

} 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;

break; } } }
