【C++ 入坑指南】（13）综合练习（实现通讯录管理系统）

效果图

需求

通讯录是一个可以记录亲人、好友信息的工具。

本文主要利用 C++ 来实现一个通讯录管理系统。

实现功能：

• 添加联系人
• 显示联系人
• 删除联系人
• 查找联系人
• 修改联系人
• 退出通讯录

代码

#include 
#include 

using namespace std;

#define MAX 1000

struct Person
{
	string m_Name;  //姓名

	int m_Sex;      // 性别 1. 男 2. 女

	int m_Age;     // 年龄

	string m_Phone;   // 电话

	string m_Address;  //地址

};

struct AddressBooks
{
	struct Person personArray[MAX];   // 联系人数组

	int m_Size;    //联系人个数
};

// 显示菜单
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) 
{
