电话簿管理系统java源码 电话簿管理程序

复习简单操作，实现一个非常非常简单的通讯录管理小程序

#include <iostream>
using namespace std;
#include <string>
constexpr auto MAX = 1000; //通讯录最大人数;

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

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

//1、添加联系人
void addPerson(Addressbooks *abs){
	//判断通讯录是否已满，满了则不再添加
	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

		//姓名
		string name;
		cout << "请输入姓名：" << endl;
		cin >> name;
		abs->personArray[abs->m_Size].m_Name = name;
		//性别
		cout << "请输入性别：" << endl;
		cout << "1——男" << endl;
		cout << "2——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;
		}
		//年龄
		cout << "请输入年龄：" << endl;
		int age = 0;
		cin >> age;
		abs->personArray[abs->m_Size].m_Age = age;
		//电话
		cout << "请输入联系电话：" << endl;
		string phone;
		cin >> phone;

	}
}

//2、显示联系人
void showPerson(Addressbooks *abs) {

	}
		system("pause");
		system("cls");
}

//3、删除联系人

	for (int i = 0; i < abs->m_Size; i++) {
		if (abs->personArray[i].m_Name == name) {
			return i;
		}
	}
	return -1;
}
/*删除指定联系人*/
void deletePerson(Addressbooks *abs) {
	cout << "请输入您要删除的联系人：" << endl;
	string name;
	cin >> name;

	int ret = isExist(abs, name);

	if (ret != -1) {
		for (int i = ret; i < abs->m_Size; i++) {
			abs->personArray[i] = abs->personArray[i + 1];
		}
		abs->m_Size--;
		cout << "删除成功" << endl;
	}
	else {
		cout << "查无此人" << endl;
	}
	system("pause");  //请按任意键继续
	system("cls");  //清屏功能
}

//4、查找联系人
void findPerson(Addressbooks *abs) {
	cout << "请输入您要查找的联系人：" << endl;
	string name;
	cin >> name;
	
	int ret = isExist(abs, name);

	if (ret != -1) {
		cout << "姓名：" << abs->personArray[ret].m_Name<<"\t";
		cout << "性别：" << (abs->personArray[ret].m_Sex == 1 ? "男" : "女") << "\t";
		cout << "年龄：" << abs->personArray[ret].m_Age << "\t";
		cout << "电话：" << abs->personArray[ret].m_Phone << "\t";

	}
	else {
		cout << "查无此人" << endl;
	}
	system("pause");  //请按任意键继续
	system("cls");  //清屏功能
}

//5、修改联系人
void modefyPerson(Addressbooks *abs) {
	cout << "请输入您要修改的联系人：" << endl;
	string name;
	cin >> name;

	int ret = isExist(abs, name);
	if (ret!=-1){
		//姓名
		string name;
		cout << "请输入姓名：" << endl;
		cin >> name;
		abs->personArray[ret].m_Name = name;
		//性别
		int sex=0;
		cout << "请输入性别：" << endl;

		while (true) {
			cin >> sex;
			if (sex == 1 || sex == 2) {
				abs->personArray[ret].m_Sex = sex;
				break;

	}
	else {
		cout << "查无此人" << endl;
	}
	system("pause");  //请按任意键继续
	system("cls");  //清屏功能
}

//6、清空联系人
void cleanPerson(Addressbooks *abs) {
	abs->m_Size = 0;   //静态内存在进程结束时自动释放，无需其他操作
	cout << "通讯录已清空" << endl;
	system("pause");  //请按任意键继续
	system("cls");  //清屏功能
}

//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;
}

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

	int select = 0;   //创建用户选择输入的变量

	while (true)
	{
		//菜单调用
		showMenu();

		cin >> select;

		switch (select)
		{
		case 1:     //1、添加联系人
			addPerson(&abs);   //利用地址传递通过修改形参来修改实参
			break;

Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.
