C++實現通訊錄系統項目實戰
本文實例為大傢分享瞭C++實現通訊錄系統項目的具體代碼，供大傢參考，具體內容如下
制作一個具有添加聯系人、刪除聯系人、修改聯系人等功能的通訊錄系統
效果圖：
代碼如下：
#include <iostream>
using namespace std;
#include <string>
#define Max 1000
//創建聯系人結構體
struct person
{
string p_name;
int p_sex; //1、男 2、女
int p_age;
string p_phone;
string p_address;
};
//創建通訊錄結構體
struct addressbooks
{
//保存的聯系人數組
struct person personarr[Max];
//當前記錄的人數
int p_size;
};
//菜單
void showmenu() {
cout << "********************************" << endl;
cout << "***** 1、添加聯系人 *****" << endl;
cout << "***** 2、顯示聯系人 *****" << endl;
cout << "***** 3、刪除聯系人 *****" << endl;
cout << "***** 4、查找聯系人 *****" << endl;
cout << "***** 5、修改聯系人 *****" << endl;
cout << "***** 6、清空聯系人 *****" << endl;
cout << "***** 0、退出通訊錄 *****" << endl;
cout << "********************************" << endl;
}
//添加聯系人
