1、菜单界面
#include<iostream>
using namespace std;
//菜单界面
void showMenu()
{
cout << "*************************" << endl;
cout << "***** 1、添加联系人 *****" << endl;
cout << "***** 2、显示联系人 *****" << endl;
cout << "***** 3、删除联系人 *****" << endl;
cout << "***** 4、查找联系人 *****" << endl;
cout << "***** 5、修改联系人 *****" << endl;
cout << "***** 6、清空联系人 *****" << endl;
cout << "***** 0、退出通讯录 *****" << endl;
cout << "*************************" << endl;
}
int main()
{
showMenu();
system("pause");
return 0;
}
2、退出功能
功能描述:退出通讯录系统
思路:根据用户不同的选择,进入不同的功能,可以选择switch分支结构,将整个架构进行搭建
当用户选择0时候,执行退出,选择其他先不做操作,也不会退出程序
int main()
{
int select = 0;
while (true)
{
showMenu();
cin >> select;
switch (select)
{
case 1://添加联系人
break;
case 2://显示联系人
break;
case 3://删除联系人
break;
case 4://查找联系人
break;
case 5: //修改联系人
break;
case 6://清空联系人
break;
case 0: //退出通讯录
cout << "欢迎下次使用" << endl;
system("pause");
return 0;
break;
default:
break;
}
}
system("pause");
return 0;
}
3、添加联系人
功能描述:
实现添加联系人功能,联系人上限为1000人,联系人信息包括(姓名、性别、年龄、联系电话、家庭住址)
添加联系人实现步骤:
3.1 设计联系人结构体
3.2 设计通讯录结构体
3.3 main函数中创建通讯录
3.4 封装添加联系人函数
3.5 测试添加联系人功能
3.1 设计联系人结构体
//联系人结构体
struct Person
{
string m_Name;
int m_Sex;
int m_Age;
string m_Phone;
string m_Addr;
};
3.2 设计通讯录结构体
//通讯录结构体
struct Addressbooks
{
struct Person personArray[MAX]; //通讯录中保存的联系人数组
int m_Size;//通讯录中人员的个数
};
3.3 main函数中创建通讯录
Addressbooks abs; //创建通讯录
abs.m_Size = 0;//初始化
int select = 0;
3.4 封装添加联系人函数
//1、添加联系人信息
void addPerson(Addressbooks *abs)
{
//判断电话本是否满了
if (abs->m_Size == MAX)
{
cout << "通讯录已满,无法添加" << endl;
return;
}
else
{
//姓名
string name;
cout << "请输入姓名:" << endl;
cin >> name;
abs->personArray[abs->m_Size].m_Name = name;
cout << "请输入性别:" << endl;
cout << "1 -- 男" << endl;
cout << "2 -- 女" << endl;
//性别
int sex = 0;
while (true)
{
cin >> sex;
if (sex == 1 || sex == 2)
{
abs->personArray[abs->m_Size].m_Sex = sex;
break;
}
cout << "输入有误,请重新输入";
}
//年龄
cout << "请输入年龄:" << endl;
int age = 0;
cin >> age;
abs->personArray[abs->m_Size].m_Age = age;
//联系电话
cout << "请输入联系电话:" << endl;
string phone = "";
cin >> phone;
abs->personArray[abs->m_Size].m_Phone = phone;
//家庭住址
cout << "请输入家庭住址:" << endl;
string address;
cin >> address;
abs->personArray[abs->m_Size].m_Addr = address;
//更新通讯录人数
abs->m_Size++;
cout << "添加成功" << endl;
system("pause");
system("cls");
}
}
3.5 测试添加联系人功能
case 1://添加联系人
addPerson(&abs);
break;
4、显示联系人
//显示联系人
void showPerson(Addressbooks*abs)
{
//判断如果当前通讯录中没有人员,就提示记录为空,人数大于0,显示通讯录中信息
if (abs->m_Size == 0)
{
cout << "当前记录为空" << endl;
}
else
{
for (int i = 0; i < abs->m_Size; i++)
{
cout << "姓名" << abs->personArray[abs->m_Size].m_Name << "\t";
cout << "性别" <<( abs->personArray[abs->m_Size].m_Sex == 1 ? "男":"女") << "\t";
cout << "年龄" << abs->personArray[abs->m_Size].m_Age << "\t";
cout << "电话" << abs->personArray[abs->m_Size].m_Phone << "\t";
cout << "住址" << abs->personArray[abs->m_Size].m_Addr << endl;
}
}
system("pause");
system("cls");
}
case 2://显示联系人
showPerson(&abs);
break;
5、删除联系人
功能描述:按照姓名进行删除指定联系人
删除联系人实现步骤:
- 封装检测联系人是否存在
- 封装删除联系人函数
- 测试删除联系人功能
5.1?封装检测联系人是否存在
//封装检测联系人是否存在
int isExist(Addressbooks* abs,string name)
{
//删除联系人前,我们需要先判断用户输入的联系人是否存在,
//如果存在删除,不存在提示用户没有要删除的联系人
for (int i = 0; i < abs->m_Size; i++)
{
if (abs->personArray[i].m_Name == name)
{
return i;
}
}
return -1;
}
5.2?封装删除联系人函数
void deletePerson(Addressbooks* abs)
{
cout << "请输入删除的联系人" << endl;
string name;
cin >> name;
int ret = isExist(abs, name);
if (ret != -1)
{
for (int i = ret; i < abs->m_Size; i++)
{
abs->personArray[i] = abs->personArray[i + 1];
}
abs->m_Size--;
cout << "删除成功" << endl;
}
else
{
cout << "查无此人" << endl;
}
system("pause");
system("cls");
}
5.3?测试删除联系人功能
6、查找联系人
//查找联系人
void findPerson(Addressbooks* abs)
{
cout << "请输入查找的联系人" << endl;
string name;
cin >> name;
int ret = isExist(abs, name);
if (ret != -1)
{
cout << "姓名:" << abs->personArray[ret].m_Name << "\t";
cout << "性别:" << abs->personArray[ret].m_Sex << "\t";
cout << "年龄:" << abs->personArray[ret].m_Age << "\t";
cout << "电话:" << abs->personArray[ret].m_Phone << "\t";
cout << "住址:" << abs->personArray[ret].m_Addr << endl;
}
else
{
cout << "查无此人" << endl;
}
system("pause");
system("cls");
}
7、修改联系人
//5、修改指定联系人信息
void modifyPerson(Addressbooks * abs)
{
cout << "请输入您要修改的联系人" << endl;
string name;
cin >> name;
int ret = isExist(abs, name);
if (ret != -1)
{
//姓名
string name;
cout << "请输入姓名:" << endl;
cin >> name;
abs->personArray[ret].m_Name = name;
cout << "请输入性别:" << endl;
cout << "1 -- 男" << endl;
cout << "2 -- 女" << endl;
//性别
int sex = 0;
while (true)
{
cin >> sex;
if (sex == 1 || sex == 2)
{
abs->personArray[ret].m_Sex = sex;
break;
}
cout << "输入有误,请重新输入";
}
//年龄
cout << "请输入年龄:" << endl;
int age = 0;
cin >> age;
abs->personArray[ret].m_Age = age;
//联系电话
cout << "请输入联系电话:" << endl;
string phone = "";
cin >> phone;
abs->personArray[ret].m_Phone = phone;
//家庭住址
cout << "请输入家庭住址:" << endl;
string address;
cin >> address;
abs->personArray[ret].m_Addr = address;
cout << "修改成功" << endl;
}
else
{
cout << "查无此人" << endl;
}
system("pause");
system("cls");
}
8、清空通讯录
//清空联系人
void cleanPerson(Addressbooks* abs)
{
abs->m_Size = 0;
cout << "通讯录已清空" << endl;
system("pause");
system("cls");
}
