C++實現通訊錄小功能
本文實例為大傢分享瞭C++實現通訊錄功能的具體代碼，供大傢參考，具體內容如下
思路：
1.顯示菜單欄
void menu() {
cout << "——————————————————" << endl;
cout << "*********** 1.添加聯系人 ***********" << endl;
cout << "*********** 2.刪除聯系人 ***********" << endl;
cout << "*********** 3.修改聯系人 ***********" << endl;
cout << "*********** 4.查找聯系人 ***********" << endl;
cout << "*********** 5.顯示通訊錄 ***********" << endl;
cout << "*********** 6.清空聯系人 ***********" << endl;
cout << "*********** 0.退出通訊錄 ***********" << endl;
cout << "——————————————————" << endl;
}
2.退出
int main() {
int select = 0;
cin >> select;
switch (select) {
case 0://退出通訊錄
cout << "歡迎下次使用" << endl;
system("pause");
return 0;
break;
}
system("pause");
return 0;
}
3.創建結構體
3.1創建聯系人結構體
3.2創建通訊錄結構體
//定義聯系人結構體
//姓名、電話號碼、郵箱、地址
struct person {
string name;
string number;
string Email;
string address;
};
// 定義通訊錄結構體
struct contacts {
int people_num;
struct person personarr[MAX];//子結構體:聯系人信息
};
4.添加聯系人
void addperson(struct contacts* p) {
if (p->people_num == MAX ) {
cout << "通訊錄已滿" << endl;
}
else {//添加聯系人信息
string name, number, Email, address;
cout << "請輸入姓名：" << endl;
cin >> name;
cout << "請輸入電話：" << endl;
cin >> number;
cout << "請輸入郵箱：" << endl;
cin >> Email;
cout << "請輸入地址：" << 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.刪除聯系人
判斷聯系人是否存在
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，獲取聯系人在通訊錄位置，將position後面的都往前移動一個位置，覆蓋之前的值
//刪除聯系人
void delperson(struct contacts* p,int position) {
while (position < (p->people_num)) {
p->personarr[position] = p->personarr[position + 1];
position++;
}
p->people_num--;
cout << "刪除成功！" << endl;
}
6.修改
檢查要修改聯系人是否存在，並獲取當前位置
void modifyperson(struct contacts* p, int position) {
string number, Email, address;
cout << "請輸入修改電話：" << endl;
cin >> number;
cout << "請輸入修改郵箱：" << endl;
cin >> Email;
cout << "請輸入修改地址：" << 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 << " "
<< "電話：" << p->personarr[position].number << " "
<< "郵箱：" << p->personarr[position].Email << " "
<< "地址：" << p->personarr[position].address << " ";
}
8.顯示通訊錄
void showcontact(struct contacts* p) {
for (int i = 0; i < (p->people_num); i++) {
cout <<"姓名：" << p->personarr[i].name << " "
<<"電話：" << p->personarr[i].number << " "
<<"郵箱：" << p->personarr[i].Email << " "
<<"地址：" << p->personarr[i].address << " "<< endl;
}
}
9.清空通訊錄
void cleancontact(struct contacts* p) {
p->people_num = 0;
cout << "已清空！" << endl;
}
全部代碼
#include<iostream>
using namespace std;
#define MAX 200
//1.菜單欄顯示
void menu() {
cout << "——————————————————" << endl;
cout << "*********** 1.添加聯系人 ***********" << endl;
cout << "*********** 2.刪除聯系人 ***********" << endl;
cout << "*********** 3.修改聯系人 ***********" << endl;
cout << "*********** 4.查找聯系人 ***********" << endl;
cout << "*********** 5.顯示通訊錄 ***********" << endl;
cout << "*********** 6.清空聯系人 ***********" << endl;
cout << "*********** 0.退出通訊錄 ***********" << endl;
cout << "——————————————————" << endl;
}
//2.定義結構體
//2.1定義聯系人結構體
//姓名、電話號碼、郵箱、地址
struct person {
string name;
string number;
string Email;
string address;
};
//2.2 定義通訊錄結構體
struct contacts {
int people_num;
struct person personarr[MAX];//子結構體:聯系人信息
};
//3.添加聯系人
void addperson(struct contacts* p) {
if (p->people_num == MAX ) {
cout << "通訊錄已滿" << endl;
}
else {//添加聯系人信息
string name, number, Email, address;
cout << "請輸入姓名：" << endl;
cin >> name;
cout << "請輸入電話：" << endl;
cin >> number;
cout << "請輸入郵箱：" << endl;
cin >> Email;
cout << "請輸入地址：" << 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.刪除聯系人
//4.1檢測聯系人是否存在
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;
}
//刪除聯系人
void delperson(struct contacts* p,int position) {
while (position < (p->people_num)) {
p->personarr[position] = p->personarr[position + 1];
position++;
}
p->people_num--;
cout << "刪除成功！" << endl;
}
//5.修改聯系人
void modifyperson(struct contacts* p, int position) {
string number, Email, address;
cout << "請輸入修改電話：" << endl;
cin >> number;
cout << "請輸入修改郵箱：" << endl;
cin >> Email;
cout << "請輸入修改地址：" << 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.查找聯系人
void searchperson(struct contacts* p, int position) {
cout << "姓名：" << p->personarr[position].name << " "
<< "電話：" << p->personarr[position].number << " "
<< "郵箱：" << p->personarr[position].Email << " "
<< "地址：" << p->personarr[position].address << " ";
}
//7.顯示通訊錄
void showcontact(struct contacts* p) {
for (int i = 0; i < (p->people_num); i++) {
cout <<"姓名：" << p->personarr[i].name << " "
<<"電話：" << p->personarr[i].number << " "
<<"郵箱：" << p->personarr[i].Email << " "
<<"地址：" << p->personarr[i].address << " "<< endl;
}
}
//8.清空聯系人
void cleancontact(struct contacts* p) {
p->people_num = 0;
cout << "已清空！" << endl;
}
int main() {
//創建通訊錄結構體變量
struct contacts c;
//初始化通訊錄當前聯系人個數
c.people_num = 0;
int select = 0;
string name;
while (1) {
menu();
cin >> select;
switch (select) {
case 1:// 添加聯系人
addperson(&c);
system("pause");
break;
case 2:// 刪除聯系人
cout << "請輸入刪除聯系人的姓名：";
cin >> name;
if (existperson(&c,name)==-1) {
cout << "該聯系人不存在！";
}
else{
delperson(&c, existperson(&c, name));
}
system("pause");
break;
case 3:// 修改聯系人
cout << "請輸入要修改聯系人的姓名：";
cin >> name;
if (existperson(&c,name) == -1) {
cout << "該聯系人不存在！";
}
else {
modifyperson(&c, existperson(&c, name));

system("pause");
break;
case 4:// 查找聯系人
cout << "請輸入查找聯系人的姓名：";
cin >> name;
if (existperson(&c,name) == -1) {
cout << "該聯系人不存在！";

searchperson(&c, existperson(&c, name));
}
system("pause");
break;
case 5:// 顯示通訊錄
showcontact(&c);
system("pause");
break;
case 6:// 清空聯系人
cleancontact(&c);
system("pause");
break;
case 0://退出通訊錄
cout << "歡迎下次使用" << endl;
