1、系统需求

本文将利用C++来实现一个通讯录管理系统

系统中需要实现的功能如下：

• 添加联系人：向通讯录中添加新人，信息包括（姓名、性别、年龄、联系电话、家庭住址）最多记录1000人
• 显示联系人：显示通讯录中所有联系人信息
• 删除联系人：按照姓名进行删除指定联系人
• 查找联系人：按照姓名查看指定联系人信息
• 修改联系人：按照姓名重新修改指定联系人
• 清空联系人：清空通讯录中所有信息
• 退出通讯录：退出当前使用的通讯录

以下是本篇文章正文内容

完整代码

#include<iostream>
#include<string>
#define MAX 1000
using namespace std;//设计联系人结构体
struct Person
{//姓名string m_Name;//性别 1 男 2 女int m_Sex;//年龄int m_Age;//电话string m_Phone;//地址string m_Addr;
};//设计通讯录结构体
struct Addressbooks
{//通讯录中保存的联系人数组struct Person PersonArray[MAX];//通讯录中当前记录的人数int m_Size;
};//1、添加联系人
void addPerson(Addressbooks * abs)
{//判断通讯录是否已经加满，如果加满则不再添加if (abs->m_Size == MAX){cout << "通讯录已满，无法添加！" << endl;}else{//添加具体联系人//姓名string name;cout << "请输入姓名：" << endl;cin >> name;abs->PersonArray[abs->m_Size].m_Name = name;//性别cout << "请输入性别：" << endl;cout << "1 --- 男" << endl;cout << "2 --- 女" << endl;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" << endl;}//年龄cout << "请输入年龄：" << endl;int age = 0;cin >> age;abs->PersonArray[abs->m_Size].m_Age = age;//电话string phone;cout << "请输入联系电话：" << endl;cin >> phone;abs->PersonArray[abs->m_Size].m_Phone = phone;//住址string address;cout << "请输入家庭地址：" << endl;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;	}}//打印联系人
//打印数组中第i个联系人
void print(Addressbooks * abs, int i)
{cout << "姓名：" << abs->PersonArray[i].m_Name << "\t";cout << "性别：" << (abs->PersonArray[i].m_Sex == 1 ? "男" : "女") << "\t";cout << "年龄：" << abs->PersonArray[i].m_Age << "\t";cout << "电话：" << abs->PersonArray[i].m_Phone << "\t";cout << "地址：" << abs->PersonArray[i].m_Addr << endl;
}//2、显示所有的联系人
void showPerson(Addressbooks * abs)
{//判断通讯录中人数是否为0，如果为0，提示记录为空if (abs->m_Size == 0){cout << "通讯录为空" << endl;}else{for (int i = 0; i < abs->m_Size; i++){print(abs, i);}}}//检测联系人是否存在，如果存在，返回联系人所在数组中的具体位置，不存在返回-1
//参数1：通讯录参数
//参数2：对比姓名
int isExit(Addressbooks * abs,string name)
{for (int i = 0; i < abs->m_Size; i++){if (abs->PersonArray[i].m_Name == name){return i;}else{return -1;}}
}//3、删除联系人
void deletePerson(Addressbooks * abs)
{cout << "请输入您要删除的联系人姓名" << endl;string name;cin >> name;//ret == -1 未查到//ret != -1 查到了int ret = isExit(abs, name);if (ret != -1){for (int i = ret;i < abs->m_Size; i++){//数据前移abs->PersonArray[i] = abs->PersonArray[i + 1];}abs->m_Size--; //更新通讯录中的人数cout << "删除成功" << endl;}else{cout << "查无此人" << endl;}
}//4、查找联系人
void findPerson(Addressbooks * abs)
{cout << "请输入您要查找的联系人：" << endl;string name;cin >> name;int ret = isExit(abs, name);if (ret != -1){print(abs, ret);}else{cout << "查无此人" << endl;}
}//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 = isExit(abs, name);if (ret != -1){cout << "请输入姓名：" << endl;string name;cin >> name;abs->PersonArray[ret].m_Name = name;cout << "请输入性别：" << endl;cout << "1 --- 男" << endl;cout << "2 --- 女" << endl;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" << endl;}cout << "请输入年龄：" << endl;int age = 0;cin >> age;abs->PersonArray[ret].m_Age = age;cout << "请输入联系电话：" << endl;string phone;cin >> phone;abs->PersonArray[ret].m_Phone = phone;cout << "请输入地址：" << endl;string address;cin >> address;abs->PersonArray[ret].m_Addr = address;cout << "修改成功！" << endl;}else{cout << "查无此人" << endl;}}//6、清空所有联系人
void clearPerson(Addressbooks* abs)
{abs->m_Size = 0; //将当前联系人数量计为0，做逻辑清空操作cout << "通讯录已清空" << endl;
}//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()
{//创建通讯录结构体变量Addressbooks abs;//初始化通讯录中当前成员个数abs.m_Size = 0;int select = 0; //创建用户输入的变量while (true){showMenu(); //菜单调用cin >> select;switch (select){case 1: //1、添加联系人addPerson(&abs);  //利用地址传递，可以修饰实参break;case 2: //2、显示联系人showPerson(&abs);break;case 3: //3、删除联系人deletePerson(&abs);break;case 4: //4、查找联系人findPerson(&abs);break;case 5: //5、修改联系人modifyPerson(&abs);break;case 6: //6、清空联系人clearPerson(&abs);break;case 0: //0、退出通讯录cout << "欢迎下次使用" << endl;system("pause");return 0;default:break;}system("pause");system("cls");}}
