通訊錄管理系統

通訊錄管理系統

添加聯系人功能：聯系人上限1000人，信息（姓名、性別、年齡、聯系電話、住址）

實現步驟：
1.設計聯系人結構體
2.設計通訊錄結構體
3.main函數中創建通訊錄
4.封裝添加聯系人函數
5.測試添加聯系人功能

關於清屏操作：
system("pause"); //按任意鍵繼續
system("cls"); //清屏

刪除聯系人：
1.檢測是否存在聯系人
2.封裝刪除聯系人
3.測試刪除聯系人功能

 

源碼如下：

#include<iostream>
#include<string>
#include<iomanip>
using namespace std;
#define MAX 1000   //最大人數

//聯系人結構體
struct Person
{
    string m_Name;   //姓名
    int m_Sex;   //性別 1 - 男 2 - 女
    int m_Age;   //年齡
    string m_Phone;   //電話
    string m_Address;   //地址
};

//通訊錄的結構體
struct Addressbooks
{
    struct Person personArray[MAX];   //通訊錄中保存的聯系人數組
    int m_Size;   //通訊錄中人員個數
};

void showMenu();  //菜單函數
void addPerson(Addressbooks* abs);  //添加聯系人
void showPerson(Addressbooks* abs);  //顯示所有聯系人
int isExist(Addressbooks* abs, string name);  //檢測聯系人是否存在，參數一 通訊錄 參數二 對比姓名
void deletePerson(Addressbooks* abs);  //刪除指定聯系人
void findPerson(Addressbooks* abs);   //查找指定聯系人信息
void modifyPerson(Addressbooks* abs);  //修改指定聯系人的信息
void cleanPerson(Addressbooks* abs);   //清除所有聯系人

int main()
{
    // 創建通訊錄結構體變量
    Addressbooks abs;
    //初始化通訊錄中當前人數
    abs.m_Size = 0;

    int select = 0;
