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
|
1
2
3
4
5
6
7
8
9
|
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
|
1
2
3
4
5
6
7
8
9
|
//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;} |
