C++实现通讯录管理系统设计 C++实现通讯录管理系统设计

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
最核心的内容是结构体，结构体数组与指针
主要功能包括：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

//封装函数显示该界面，如 void showMenu()//在mian函数中调用封装好的函数#include #include #define MAX 1000using namespace std; //设计联系人结构体struct Person{//姓名string m_Name; //性别int m_Sex; //年龄int m_Age; //电话string m_Phone; //住址string m_Addr; }; //设计通讯录结构体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; }; // 1、添加联系人void addPerson(Addressbooks *abs){//判断通讯录是否已满，如果满了就不再添加if (abs->m_Size == MAX){cout << "通讯录已满，无法添加" << endl; return; }else {//添加具体联系人//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：" << endl; cout << "1 -- 男" << endl; cout << "2 -- 女" << endl; int sex = 0; while (true){//如果输入的是1或者2可以退出循环，因为输入的是正确值//如果输入有误，重新输入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cout << "请输入年龄：" << endl; int age = 0; cin >> age; abs->personArray[abs->m_Size].m_Age = age; //电话cout << "请输入联系电话：" << endl; string phone; cin >> phone; abs->personArray[abs->m_Size].m_Phone = phone; //住址cout << "请输入家庭地址：" << endl; string address; 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"); //请按任意键继续system("cls"); //清屏操作}}//2、显示所有联系人void showPerson(Addressbooks * abs){//判断通讯录中人数是否为0，如果为0，提示记录为空//如果不为0，显示记录的联系人信息if (abs->m_Size == 0){cout << "当前记录为空" << endl; }else{for (int i = 0; i < abs->m_Size; i++){cout << "姓名: " << abs->personArray[i].m_Name << "\t"; //空格cout << "性别: " << (abs->personArray[i].m_Sex == 1 ?
