此项目适合c++初学者,针对c++基础知识,涉及到变量、结构体定义使用、数组定义使用、指针定义使用等。 运行之后的结果如下: 代码: #include<iostream></iostream> #include<string></string> using namespace std; #define MAX 1000//定义通讯录最大容量为1000 //联系人结构体 struct person { string name; int sex; int age; string address; }; //通讯录结构体 struct contact { struct person p[MAX]; int size; }; //操作菜单 void showMenu() { cout << "*********通讯录管理系统**********" << endl; cout << "********* 1.增加联系人 **********" << endl; cout << "********* 2.删除联系人 **********" << endl; cout << "********* 3.修改联系人 **********" << endl; cout << "********* 4.查询联系人 **********" << endl; cout << "********* 5.显示联系人 **********" << endl; cout << "********* 6.清空通讯录 **********" << endl; cout << "********* 0.退出通讯录 **********" << endl; } //封装查询联系人是否存在 int isExist(contact* con, string name) { for (int i = 0; i < con->size; i++) { if (con->p[i].name == name) { return i; } } return -1; } //添加联系人函数 void addPerson(contact *con){//传入数组的指针 if (con->size == MAX) { cout << "通讯录已满"<<endl; } else { cout << "输入姓名"; string name; cin >> name; cout << "输入年龄"; int age; cin >> age; cout << "输入性别1:女 2:男"; int sex; cin >> sex; cout << "输入地址"; string address; cin >> address; con->p[con->size].name = name; con->p[con->size].age = age; con->p[con->size].sex = sex; con->p[con->size].address = address; con->size++; } cout << "添加成功"<<endl; system("pause"); } //删除联系人函数 void deletecon(contact* con) { string name; cout << "输入要删除的姓名"; cin >> name; int res = isExist(con,name); if (res != -1) { for (int i = res; i < con->size; i++) { con->p[res] = con->p[res + 1]; } cout << "删除成功" << endl; con->size--; } else { cout << "查无此人"<<endl; } system("pause"); } //修改联系人函数 void updateContact(contact* con) { string name; cout << "输入要修改的联系人姓名查询" << endl; cin >> name; int res = isExist(con, name); if (res != -1) { cout << "姓名:" << con->p[res].name << "年龄:" << con->p[res].age << "性别:" << (con->p[res].sex == 1 ?
