C++实现简易通讯录

本文实例为大家分享了C++实现简易通讯录的具体代码，供大家参考，具体内容如下

#include <iostream>
#include <string>
#define MAX 1000
using namespace std;

// 设计联系人的结构体
struct Person
{
 string m_Name;
 int m_Sex;  // 1、男  2 女
 int m_Age;
 string m_Phone;
 string m_Addr;
};

// 设计通讯录的结构体
struct Addressbooks
{
 struct Person personArray[MAX];
 int m_Size;
};

// 1、菜单界面
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;
}
// 2、添加联系人
void addPerson(Addressbooks * abs)
{
 // 判断通讯录是否已满
 if (abs->m_Size == MAX)
 {
 cout << "通讯录已经满，无法添加！" << endl;
 return;
 }
 else
 {
 // 添加具体联系人
 string name;
 cout << "请输入姓名：" << endl;
 cin >> name;
 abs->personArray[abs->m_Size].m_Name = name;
 cout << "请输入性别：" << endl;
 cout << "1----男\n2----女" << endl;
 int sex = 0;
 while (true)
 {
  cin >> sex;
  if (sex == 1 || sex == 2)
  {
  abs->personArray[abs->m_Size].m_Sex = sex;
  break;
  }
  cout << "输入有误，请重新输入" << endl;
 }
 cout << "请输入年龄：" << endl;
 int age = 0;
 cin >> age;

 abs->m_Size++;

 cout << "添加成功！" << endl;

 system("pause"); // 请按任意键继续
 system("cls");  // 清屏操作
 }

}

// 3、显示所有的联系人
void showPerson(Addressbooks * abs)
{

 }
 }

}

// 4、检测联系人是否存在，若存在，返回联系人所在数组中的具体位置
// 参数1 通讯录  参数2 对比姓名
int isExit(Addressbooks * abs, string name)
{
 for (int i = 0; i < abs->m_Size; i++)

 if (abs->personArray[i].m_Name == name)
 {
  return i;  //找到了，返回该人在数组中的编号
 }
 }
 return -1;     // 没有找到，则返回-1

// 5、删除指定的联系人

// 7、修改指定的联系人信息

// 8、清空联系人
void cleanPerson(Addressbooks * abs)
{

 cout << "联系人已经清空！！！" << endl;
 system("pause");
 system("cls");
}

int main()
