C++通讯录管理系统-创新互联

一、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
  • 清空联系人
  • 退出通讯录
二、代码参考
#include#includeusing namespace std;

#define MAX 1000

//设计联系人结构体
struct Person
{//姓名
	string m_Name;
	//性别
	int m_Sex;
	//年龄
	int m_Age;
	//电话
	string m_Phone;
	//住址
	string m_Addr;

};

//设计通讯录结构体
struct Addressbooks
{//通讯录中保存的联系人数组
	Person personArray[MAX];
	//通讯录中当前记录联系人个数
	int m_Size;
};

//菜单界面
void showMenu()
{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;
}

//所有功能

//1.添加联系人
void addPerson(Addressbooks* abs)
{//判断通讯录是否已满，满了就不再添加
	if (abs->m_Size == MAX)
	{cout<< "通讯录已满，无法添加！"<< endl;
		return;
	}
	else
	{//添加具体联系人

		string name;
		cout<< "请输入姓名:";
		cin >>name;
		abs->personArray[abs->m_Size].m_Name = name;

		int sex;
		cout<< "请输入性别:"<	cin >>sex;
			if (sex == 1 || sex == 2)
			{		abs->personArray[abs->m_Size].m_Sex = sex;
				break;
			}
			else
			{		cout<< "请重新输入"<>age;
		abs->personArray[abs->m_Size].m_Age = age;

		string phone;
		cout<< "请输入联系电话：";
		cin >>phone;
		abs->personArray[abs->m_Size].m_Phone = phone;

		string address;
		cout<< "请输入家庭住址：";
		cin >>address;
		abs->personArray[abs->m_Size].m_Addr = address;

		abs->m_Size++;

		cout<< "添加成功"<//判断通讯录中人数是否为0
	if (abs->m_Size == 0)
	{cout<< "当前记录为空"<< endl;
	}
	else
	{for (int i = 0; i< abs->m_Size; i++)
		{	cout<< "姓名："<< abs->personArray[i].m_Name<< " ";
			cout<< "性别："<< (abs->personArray[i].m_Sex==1?"男":"女")<< " ";
			cout<< "年龄："<< abs->personArray[i].m_Age<< " ";
			cout<< "电话："<< abs->personArray[i].m_Phone<< " ";
			cout<< "住址："<< abs->personArray[i].m_Addr<< endl;
		}
	}
	system("pause");//按任意键继续
	system("cls");//清屏
}

//3.删除联系人
//3.1检测联系人是否存在
int isExist(Addressbooks *abs,string name)
{for (int i = 0; i< abs->m_Size; i++)
	{if (abs->personArray[i].m_Name == name)
		{	return i;//返回通讯录中的数组下标
		}
	}
	return -1;
}
//3.2删除指定联系人
void deletePerson(Addressbooks *abs)
{string name;
	cout<< "请输入您要删除的联系人"<< endl;
	cin >>name;
	int index = isExist(abs, name);//这里只传abs的原因是abs就是代表了地址了
	if(index==-1)
	{cout<<"未查到此人"<for (int i = index; i< abs->m_Size - 1; i++)
		{	//数据前移
			abs->personArray[i] = abs->personArray[i + 1];
		}
		abs->m_Size--;
		cout<< "删除成功"<< endl;
	}
	system("pause");
	system("cls");
}


//4.查找联系人
void findPerson(Addressbooks* abs)
{string name;
	cout<< "请输入您要查找的联系人"<< endl;
	cin >>name;
	int index = isExist(abs, name);
	if ( index== -1)
	{cout<< "找不到这个联系人"<< endl;
	}
	else
	{cout<< "姓名："<< abs->personArray[index].m_Name<< " ";
		cout<< "性别："<< (abs->personArray[index].m_Sex == 1 ? "男" : "女")<< " ";
		cout<< "年龄："<< abs->personArray[index].m_Age<< " ";
		cout<< "电话："<< abs->personArray[index].m_Phone<< " ";
		cout<< "住址："<< abs->personArray[index].m_Addr<< endl;
	}
	system("pause");
	system("cls");
}

//5.修改联系人
void modifyPerson(Addressbooks* abs)
{string name;
	cout<< "请输入要修改的联系人姓名"<< endl;
	cin >>name;
	int index = isExist(abs, name);
	if (index == -1)
	{cout<< "查无此人"<< endl;
	}
	else
	{//修改
		string name;
		cout<< "请输入姓名:";
		cin >>name;
		abs->personArray[index].m_Name = name;

		int sex;
		cout<< "请输入性别:"<< endl;
		cout<< "1---男"<< endl;
		cout<< "2---女"<< endl;

		while (true)
		{	cin >>sex;
			if (sex == 1 || sex == 2)
			{		abs->personArray[index].m_Sex = sex;
				break;
			}
			else
			{		cout<< "请重新输入"<< endl;
			}
		}

		int age;
		cout<< "请输入年龄：";
		cin >>age;
		abs->personArray[index].m_Age = age;

		string phone;
		cout<< "请输入联系电话：";
		cin >>phone;
		abs->personArray[index].m_Phone = phone;

		string address;
		cout<< "请输入家庭住址：";
		cin >>address;
		abs->personArray[index].m_Addr = address;

		abs->m_Size= abs->m_Size;//只是修改，保存原来人数

		cout<< "修改成功"<< endl;
	}
	system("pause");
	system("cls");
}

//6.清空联系人
void cleanPerson(Addressbooks* abs)
{int judge = 0;
	cout<< "确认是否清空 1--是，2--否"<< endl;
	cin >>judge;
	if (judge == 2)
	{cout<< "取消清空，返回菜单"<< endl;
	}
	else if(judge==1)
	{abs->m_Size = 0;				//逻辑清空
		cout<< "通讯录已清空"<< endl;
	}
	system("pause");
	system("cls");
}

int main()
{//创建通讯里结构体变量
	Addressbooks abs;
	//初始化通讯录中当前人员个数
	abs.m_Size = 0;


	int select = 0;

	while (true)
	{//菜单调用
		showMenu();

		cin >>select;

		switch (select)
		{case 1:
			addPerson(&abs);
			break;
		case 2:
			showPerson(&abs);
			break;
		case 3:
		{		//case中加括号的原因是string name在switch语句中重复定义了，必须括起来变成局部变量
			deletePerson(&abs);
			break; 
		}
		case 4:
			findPerson(&abs);
			break;
		case 5:
			modifyPerson(&abs);
			break;
		case 6:
			cleanPerson(&abs);
			break;
		case 0:
			cout<< "欢迎下次使用"<< endl;
			system("pause");
			return 0;
			break;
		default:
			break;
		}
	}

	system("pause");
	
	return 0;
}
