C++实现通讯录的相关功能

C++实现通讯录的相关功能

1.实现功能

 1.显示操作目录
 2.添加联系人
 3.显示联系人
 4.删除联系人
 5.修改联系人
 6.清空通讯录
 7.退出通讯录

2.思路梳理

创建两个结构体：一个表示通讯录（包括，联系人和联系人数量），一个表示联系人（保存联系人的姓名、年龄、性别、电话、家庭住址）.对结构体进行相关操作

3.结构体的建立

struct Person{
	string name;
	string sex;
	int age;
	string tele;
	string address;
};

struct addressBook
{
	struct Person myFriend[MAX];
	int num;
};

4.主函数设计

int main() {
	int flag = 1;
	addressBook myBook;
	myBook.num = 0;

	while (flag) {
		showMenu();
		cout << endl << "请选择操作：" << endl;
		cin >> flag;
		switch (flag)
		{
		case 1:
			addBook(&myBook);
			break;
		case 2:
			showBook(&myBook);
			break;
		case 3:
			deleBook(&myBook);
			break;
		case 4:
			findBook(&myBook);
			break;
		case 5:
			modifyBook(&myBook);
			break;
		case 6:
			cleanBook(&myBook);
			break;
		default:
			break;
		}
	}
	cout << "欢迎下次使用！";
	
}

5.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;
}

6.添加联系人

void addBook(struct addressBook *book) {
	if (book->num >= MAX) {
		cout << "超出限制";
	}
	else {
		cout << "请输入联系人姓名：";
		cin >> book->myFriend[book->num].name;

		cout << "请输入联系人性别：";
		cin >> book->myFriend[book->num].sex;

		cout << "请输入联系人年龄：";
		cin >> book->myFriend[book->num].age;

		cout << "请输入联系人电话：";
		cin >> book->myFriend[book->num].tele;

		cout << "请输入联系人地址：";
		cin >> book->myFriend[book->num].address;

		book->num += 1;
	}
	cout << "添加成功！" << endl << endl;
}

7.显示通讯录

void showBook(struct addressBook *book) {
	if (book->num == 0) {
		cout << "没有联系人" << endl;
	}
	else {
		for (int i = 0; i < book->num; i++) {
			cout << "联系人" << i+1 << "：" << endl;
			cout << "联系人姓名：" << book->myFriend[i].name << endl;
			cout << "联系人性别：" << book->myFriend[i].sex << endl;
			cout << "联系人年龄：" << book->myFriend[i].age << endl;
			cout << "联系人电话：" << book->myFriend[i].tele << endl;
			cout << "联系人地址：" << book->myFriend[i].address << endl << endl;
		}
	}
}

8.判断联系人是否存在

int isExist(string deleName,struct addressBook book) {
	for (int i = 0; i < book.num; i++) {
		if (deleName == book.myFriend[i].name) {
			return i;
		}
	}
	return -1;
}

9.删除联系人

int deleBook(struct addressBook* book) {
	string deleName;
	int flag=0;
	if (book->num == 0) {
		cout << "没有联系人" << endl;
		return 0;
	}
	cout << "输入删除联系人姓名：";
	cin >> deleName;
	flag = isExist(deleName,*book);
	if (flag != -1) {
		for (int i = flag; i < book->num - 1; i++) {
			book->myFriend[i] = book->myFriend[i + 1];
		}
		book->num -= 1;
		cout << "删除成功！" << endl << endl;
	}
	else {
		cout << "没有联系人" << endl << endl;
	}
	
}

10.查找联系人

void findBook(struct addressBook* book) {
	string findName;
	int flag;
	cout << "输入查询联系人姓名：";
	cin >> findName;
	flag = isExist(findName, *book);
	if (flag != -1) {
		cout << "联系人姓名：" << book->myFriend[flag].name << endl;
		cout << "联系人性别：" << book->myFriend[flag].sex << endl;
		cout << "联系人年龄：" << book->myFriend[flag].age << endl;
		cout << "联系人电话：" << book->myFriend[flag].tele << endl;
		cout << "联系人地址：" << book->myFriend[flag].address << endl << endl;
	}
	else {
		cout << "没有该联系人！" << endl << endl;
	}
}

11.修改联系人

void modifyBook(struct addressBook* book) {
	string modifyName;
	cout << "输入需要修改的联系人姓名：" ;
	cin >> modifyName;
	int flag;
	flag = isExist(modifyName, *book);
	if (flag != -1) {
		cout << "请输入联系人姓名：";
		cin >> book->myFriend[flag].name;

		cout << "请输入联系人性别：";
		cin >> book->myFriend[flag].sex;

		cout << "请输入联系人年龄：";
		cin >> book->myFriend[flag].age;

		cout << "请输入联系人电话：";
		cin >> book->myFriend[flag].tele;

		cout << "请输入联系人地址：";
		cin >> book->myFriend[flag].address;

		cout << "修改成功！" << endl << endl;
	}
	else {
		cout << "没有该联系人!" << endl << endl;
	}
}

12.清空联系人

void cleanBook(struct addressBook* book) {
	char flag;
	cout << "确定清空联系人？ 输入‘y’确定";
	cin >> flag;
	if (flag == 'y') {
		book->num = 0;
		cout << "清空成功！" << endl << endl;
	}
	else {
		cout << "取消清空！" << endl << endl;
	}
}
