本文实例为大家分享了C++实现通讯录功能的具体代码,供大家参考,具体内容如下
思路:
1.显示菜单栏
- void menu() {
- ?
- ?? ?cout << "——————————————————" << endl;
- ?? ?cout << "*********** 1.添加联系人 ***********" << endl;
- ?? ?cout << "*********** 2.删除联系人 ***********" << endl;
- ?? ?cout << "*********** 3.修改联系人 ***********" << endl;
- ?? ?cout << "*********** 4.查找联系人 ***********" << endl;
- ?? ?cout << "*********** 5.显示通讯录 ***********" << endl;
- ?? ?cout << "*********** 6.清空联系人 ***********" << endl;
- ?? ?cout << "*********** 0.退出通讯录 ***********" << endl;
- ?? ?cout << "——————————————————" << endl;
- }
2.退出
- int main() {
- ?
- ?? ?int select = 0;
- ?? ?cin >> select;
- ?? ?switch (select) {
- ?? ??? ?
- ?? ??? ?case 0://退出通讯录
- ?? ??? ? ? ?cout << "欢迎下次使用" << endl;
- ?? ??? ??? ?system("pause");
- ?? ??? ??? ?return 0;
- ?? ??? ??? ?break;
- ?? ??? ?
- ?? ?}
- ?? ?
- ?? ?system("pause");
- ?? ?return 0;
- }
3.创建结构体
3.1创建联系人结构体
3.2创建通讯录结构体
- //定义联系人结构体
- //姓名、电话号码、邮箱、地址
- struct person {
- ?? ?string name;
- ?? ?string number;
- ?? ?string Email;
- ?? ?string address;
- };
- // 定义通讯录结构体
- struct contacts {
- ?? ?int people_num;
- ?? ?struct person personarr[MAX];//子结构体:联系人信息
- };
4.添加联系人
- void addperson(struct contacts* p) {
- ?? ?if (p->people_num == MAX ) {
- ?? ??? ?cout << "通讯录已满" << endl;
- ?? ?}
- ?? ?else {//添加联系人信息
- ?? ??? ?string name, number, Email, address;
- ?? ??? ?cout << "请输入姓名:" << endl;
- ?? ??? ?cin >> name;
- ?? ??? ?cout << "请输入电话:" << endl;
- ?? ??? ?cin >> number;
- ?? ??? ?cout << "请输入邮箱:" << endl;
- ?? ??? ?cin >> Email;
- ?? ??? ?cout << "请输入地址:" << endl;
- ?? ??? ?cin >> address;
- ?? ??? ?p->personarr[p->people_num].name = name;
- ?? ??? ?p->personarr[p->people_num].number = number;
- ?? ??? ?p->personarr[p->people_num].Email = Email;
- ?? ??? ?p->personarr[p->people_num].address = address;
- ?? ??? ?
- ?? ??? ?p->people_num++;
- ?? ??? ?cout << "添加成功!" << endl;
- ?? ?}
- }
5.删除联系人
判断联系人是否存在
- int existperson(struct contacts* p,string name) {
- ?? ?
- ?? ?for (int i = 0; i < p->people_num; i++) {
- ?? ??? ?if ( p->personarr[i].name == name ) {
- ?? ??? ??? ?return i;
- ?? ??? ?}
- ?? ?}
- ?? ?return -1;
- }
若存在,获取联系人在通讯录位置,将position后面的都往前移动一个位置,覆盖之前的值
- //删除联系人
- void delperson(struct contacts* p,int position) {
- ?? ?while (position < (p->people_num)) {
- ?? ??? ?p->personarr[position] = p->personarr[position + 1];
- ?? ??? ?position++;
- ?? ?}
- ?? ?p->people_num--;
- ?? ?cout << "删除成功!" << endl;
- }
6.修改
检查要修改联系人是否存在,并获取当前位置
- void modifyperson(struct contacts* p, int position) {
- ?? ?string ?number, Email, address;
- ?? ?
- ?? ?cout << "请输入修改电话:" << endl;
- ?? ?cin >> number;
- ?? ?cout << "请输入修改邮箱:" << endl;
- ?? ?cin >> Email;
- ?? ?cout << "请输入修改地址:" << endl;
- ?? ?cin >> address;
- ?
- ?? ?p->personarr[position].number = number;
- ?? ?p->personarr[position].Email = Email;
- ?? ?p->personarr[position].address = address;
- ?? ?cout << "修改成功!" << endl;
- }
7.查找
- void searchperson(struct contacts* p, int position) {
- ?? ?cout << "姓名:" << p->personarr[position].name << " ? ?"
- ?? ??? ?<< "电话:" << p->personarr[position].number << " ? ?"
- ?? ??? ?<< "邮箱:" << p->personarr[position].Email << " ? ?"
- ?? ??? ?<< "地址:" << p->personarr[position].address << " ? ?";
- }
8.显示通讯录
- void showcontact(struct contacts* p) {
- ?? ?for (int i = 0; i < (p->people_num); i++) {
- ?? ??? ?cout <<"姓名:" << p->personarr[i].name << " ? ?"
- ?? ??? ??? ?<<"电话:" << p->personarr[i].number << " ? ?"
- ?? ??? ??? ?<<"邮箱:" << p->personarr[i].Email << " ? ?"
- ?? ??? ??? ?<<"地址:" << p->personarr[i].address << " ? ?"<< endl;
- ?
- ?? ?}?? ??? ?
- }
9.清空通讯录
- void cleancontact(struct contacts* p) {
- ?? ?p->people_num = 0;
- ?? ?cout << "已清空!" << endl;
- }
全部代码
- #include<iostream>
- using namespace std;
- #define MAX 200?
- ?
- //1.菜单栏显示
- void menu() {
- ?
- ?? ?cout << "——————————————————" << endl;
- ?? ?cout << "*********** 1.添加联系人 ***********" << endl;
- ?? ?cout << "*********** 2.删除联系人 ***********" << endl;
- ?? ?cout << "*********** 3.修改联系人 ***********" << endl;
- ?? ?cout << "*********** 4.查找联系人 ***********" << endl;
- ?? ?cout << "*********** 5.显示通讯录 ***********" << endl;
- ?? ?cout << "*********** 6.清空联系人 ***********" << endl;
- ?? ?cout << "*********** 0.退出通讯录 ***********" << endl;
- ?? ?cout << "——————————————————" << endl;
- }
- ?
- //2.定义结构体

- ?? ??? ?cout << "请输入姓名:" << endl;
- ?? ??? ?cin >> name;
- ?? ??? ?cout << "请输入电话:" << endl;
- ?? ??? ?cin >> number;
- ?? ??? ?cout << "请输入邮箱:" << endl;
- ?? ??? ?cin >> Email;
- ?? ??? ?cout << "请输入地址:" << endl;
- ?? ??? ?cin >> address;
- ?? ??? ?p->personarr[p->people_num].name = name;
- ?? ??? ?p->personarr[p->people_num].number = number;
- ?? ??? ?p->personarr[p->people_num].Email = Email;
- ?? ??? ?p->personarr[p->people_num].address = address;
- ?? ??? ?
- ?? ??? ?p->people_num++;
- ?? ??? ?cout << "添加成功!" << endl;
- ?? ?}
- }
- //4.删除联系人
