本文实例为大家分享了C++实现通讯录管理系统的具体代码，供大家参考，具体内容如下
1、通讯录设计要点
1：添加联系人：向通讯录中添加新人（包括：性别，年龄，联系电话，家庭住址），并且最多记录1000人
2：显示联系人：显示通讯录中所有联系人信息
3：删除联系人：按照姓名进行删除指定联系人
4：查找联系人：按照姓名查找联系人
5：修改联系人：按照姓名修改联系人
6：清空联系人：按照姓名清空联系人
7：退出通讯录：退出当前使用的通讯录
2、设计思路
// 引入C++标准包
#include <iostream>
#include <string>
// #define MAX_NUMBER 2
using namespace std;
// const int MAX_NUMBER2 = 3;
// 定义常量通讯录最大值 (auto 让编译其自己推断变量的类型)
constexpr auto MAX = 3;
// 定义联系人结构体
struct Person
{
string name;
int sex;
int age;
string phoneNamer;
string address;
};
struct addressbook
{
struct Person perArray[MAX];
// struct Person personArr[MAX_NUMBER2];
// struct Person personArr[MAX_NUMBER];
int person_size;
};
// 展示通讯录系统
void showMenu() {
cout << "欢迎来到通讯录管理系统" << endl;
cout << "功能1：添加联系人" << endl;
cout << "功能2：显示联系人" << endl;
cout << "功能3：删除联系人" << endl;
cout << "功能4：查找联系人" << endl;
cout << "功能5：修改联系人" << endl;
cout << "功能6：清空联系人" << endl;
cout << "功能0：退出通讯录系统" << endl;
}
int isExist(addressbook* personBook , string name) {
for (int i = 0; i < personBook->person_size;i++)
{
if (personBook->perArray[i].name == name)
{
// 从通讯录中找到了某个人
return i;
}
}
return -1;
}
void addPerson(addressbook *addBook) {
if (addBook->person_size < MAX)
{
cout << "请输入姓名：" << endl;
string name;
cin >> name;
// addBook 操作指针指向的哪个对象
addBook->perArray[addBook->person_size].name = name;

int sex;
// 通过while死循环持续性的读取用户输入的性别
