作者：青衫哥
这篇文章主要为大家详细介绍了C++实现通讯录系统项目实战，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
本文实例为大家分享了C++实现通讯录系统项目的具体代码，供大家参考，具体内容如下
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)
{

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

break;
}
cout << "请重新输入" << endl;
}
}
//年龄
cout << "请输入年龄" << endl;
