1.信息存储

1.设置联系人结构体

/*设置联系人结构体*/
struct Pepole {
	//姓名
	string L_name;
	//性别 1 男 2女
	int L_sex;
	//年龄
	int L_age;
	//电话
	string L_phone;
	//住址
	string L_addr;
};

2.设置通讯录结构体

/*设置通讯录结构体*/
struct Addressbooks {
	//通讯录中保存的联系人数组
	struct Pepole person[MAX];
	//当前记录通讯录中联系人的个数
	int L_size;

};

2.菜单界面

/*菜单界面*/
void ShowJM()
{
	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;
}

3.判断联系人是否存在

/*判断联系人是否存在*/
int isExist(Addressbooks* variablea,string name)
{
	for (int i = 0; i < variablea->L_size; i++)
	{
		if (variablea->person[i].L_name == name)
		{
			return i;
		}
	}
	return -1;
}

4.功能

1.添加功能

/*1、添加联系人*/

		return;
	}
	else
	{
		//添加联系人

		//姓名
		string name;
		cout << "请输入姓名：" << endl;
		cin >> name;
		variablea->person[variablea->L_size].L_name = name;
		//性别
		cout << "请输入性别：" << endl;
		cout << "1--男，2--女" << endl;
		int sex = 0;
		while (true) {
			cin >> sex;
			if (sex == 1 || sex == 2)
			{
				variablea->person[variablea->L_size].L_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;
		while (true)
		{
			cin >> age;
			if (age > 0)
			{
				variablea->person[variablea->L_size].L_age = age;
				break;
			}
			cout << "输入有误，请重新输入" << endl;
		}
		//电话
		cout << "请输入电话：" << endl;
		string phone ;
		cin >> phone;
		variablea->person[variablea->L_size].L_phone = phone;
		//住址

		variablea->person[variablea->L_size].L_addr = addr;
		variablea->L_size++;
		cout << "添加成功" << endl;
		system("papuse"); 
		system("cls"); //清屏操作
	}
}

2.显示功能

/*2、显示联系人*/
void showPepole(Addressbooks* variablea)
{
	//判断通讯录人数是否为空
	if (variablea->L_size == 0) cout << "当前为空" << endl;
	else {
		for (int i = 0; i < variablea->L_size; i++)
		{
			cout << "姓名：" << variablea->person[i].L_name << "\t";
			cout << "性别：" << (variablea->person[i].L_sex ==1 ? "男":"女") << "\t";
			cout << "年龄：" << variablea->person[i].L_sex << "\t";
			cout << "电话：" << variablea->person[i].L_phone <<"\t";

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

3.删除功能

/*3、删除联系人*/
void deletePepole(Addressbooks * variablea)
{
	cout << "请输入您要删除的联系人" << endl;
	string name;
	cin >> name;
	int len = isExist(variablea, name);
	if (len == -1) {
		cout << "查无此人" << endl;
	}
	else
	{
		for (int i = len; i < variablea->L_size; i++)
		{
			//数据前移
			variablea->person[i] = variablea->person[i + 1];
		}
		variablea->L_size--;//更新通讯录中的人员数
		cout << "删除成功" << endl;
	}
	system("pause");
	system("cls");
}

4.查找功能

void findPepole(Addressbooks *variablea)
{
	cout << "请输入您要查找的联系人" << endl;
	string name;
	cin >> name;
	int len = isExist(variablea, name);
	if (len == -1)
	{
		cout << "查无此人" << endl;
	}
	else
	{
		cout << "姓名：" << variablea->person[len].L_name << "\t";
		cout << "性别：" << (variablea->person[len].L_sex == 1 ? "男" : "女") << "\t";

	//初始化通讯录中当前人员个数
	variable.L_size = 0;

	int select_input = 0; //用户选择输入
	while (true) {
		ShowJM();
		cin >> select_input;
		switch (select_input)
		{
		case 1: //1、添加联系人

			break;
		case 5: //5、修改联系人
			fixPepole(&variable);
			break;
		case 6: // 6、清空联系人
		{
			cout << "您是否确定要清空所要联系人" << endl;
			cout << "输入Yes为确定清空，输入No为放弃清空" << endl;
			char ch[10];
			while (true)
			{
				cin >> ch;
				if (strcmp(ch, "Yes") == 0)
				{
					cleanPepole(&variable);
					break;
				}
				else if (strcmp(ch, "No") == 0) {
