本篇内容介绍了“C++如何实现通讯录系统”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！
制作一个具有添加联系人、删除联系人、修改联系人等功能的通讯录系统
效果图：
代码如下：
#include <iostream>
using namespace std;
#include <string>
#define Max 1000
//创建联系人结构体
struct person
{
string p_name;
int p_sex; //1、男 2、女
int p_age;
string p_phone;
string p_address;
};
//创建通讯录结构体
struct addressbooks
{
//保存的联系人数组
struct person personarr[Max];
//当前记录的人数
int p_size;
};
//菜单
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;
}
//添加联系人
void addperson(addressbooks* abs)
{
//先判断通讯录是否已满
if (abs->p_size == Max)
{
cout << "通讯录已满" << endl;
return;
}
else
{
string name;
cout << "请输入姓名: " << endl;
cin >> name;
abs->personarr[abs->p_size].p_name = name;
cout << "请输入性别: " << endl;
cout << "输入1 -- 男" << endl;
cout << "输入2 -- 女" << endl;
int sex = 0;
while (true)
{
cin >> sex;
if (sex == 1 || sex == 2)
{
//输入1或者2,退出循环. 输入其他数字重新循环
abs->personarr[abs->p_size].p_sex = sex;
break;
}
cout << "请重新输入" << endl;
}
}
//年龄
cout << "请输入年龄" << endl;
int age = 0;
cin >> age;
abs->personarr[abs->p_size].p_age = age;
//电话
cout << "请输入联系电话" << endl;
string phone;

//地址
cout << "请输入地址" << endl;

//更新通讯录

cout << "电话: " << abs->personarr[i].p_phone << "\t";
cout << "地址: " << abs->personarr[i].p_address << endl;
}
}
//清屏回到最初菜单
system("pause");
system("cls");
}
//检测联系人是非存在通讯录中,如果存在,返回该联系人在通讯录中的位置,不存在返回-1
int isExist(addressbooks* abs, string name)
