C++实现通讯录小功能
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
//2.1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;
};
//2.2 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
};
//3.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;
}
}
//4.删除联系人
//4.1检测联系人是否存在
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;
}
//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;
}
//5.修改联系人
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;
}
//6.查找联系人
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 << " ";
}
//7.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;
}
}
//8.清空联系人
void cleancontact(struct contacts* p) {
p->people_num = 0;
cout << "已清空！" << endl;
}
int main() {
//创建通讯录结构体变量
struct contacts c;
//初始化通讯录当前联系人个数
c.people_num = 0;
int select = 0;
string name;
while (1) {
menu();
cin >> select;
switch (select) {
case 1:// 添加联系人
addperson(&c);
system("pause");
break;
case 2:// 删除联系人
cout << "请输入删除联系人的姓名：";
cin >> name;
if (existperson(&c,name)==-1) {
cout << "该联系人不存在！";
}
else{
delperson(&c, existperson(&c, name));
}
system("pause");
break;
case 3:// 修改联系人
cout << "请输入要修改联系人的姓名：";
cin >> name;
if (existperson(&c,name) == -1) {
cout << "该联系人不存在！";
}
else {
modifyperson(&c, existperson(&c, name));
}
system("pause");
break;
case 4:// 查找联系人
cout << "请输入查找联系人的姓名：";
cin >> name;
if (existperson(&c,name) == -1) {
cout << "该联系人不存在！";
}
else {
searchperson(&c, existperson(&c, name));
}
system("pause");
break;
case 5:// 显示通讯录
showcontact(&c);
system("pause");
break;
case 6:// 清空联系人
cleancontact(&c);
system("pause");
break;
case 0://退出通讯录
cout << "欢迎下次使用" << endl;
system("pause");//暂停批文件的处理
return 0;
break;
}
system("cls");//清屏
