通讯录管理系统的设计实现

我要做的

一想到“管理系统”，我们脑海里通常浮现四个字，增查删改。这也是必不可少的部分。
我先把这个系统我要实现的部分列举出来（当然，我的思路有很多不足，恳请大佬指正，批评，不胜感激）

  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.退出系统***********" << endl;

（备注：退出也是其中一个功能哦）

首先，构建结构体变量

#define MAX 1000

struct person
{
	string name;
	int sex{ };
	int age{ };
	string phonenumber;
	string address;
};
struct addressbook
{
	struct person personArr[MAX];
	int person_size{ };

下面，根据上述功能，依次实现相关函数如下：

添加联系人

void addPerson(addressbook* aaa) //添加联系人模块
{
	if (aaa->person_size < MAX)
	{
			string name;
			cout << "请输入姓名：" << endl;
			cin >> name;
			aaa->personArr[aaa->person_size].name = name;

			int sex;
			cout << "请输入性别对应序号：（1--男    2--女)" << endl;
			while (true)
			{
				cin >> sex;
				if ((sex == 1) || (sex == 2))
				{
					aaa->personArr[aaa->person_size].sex = sex;
					break;
				}
				else
				{
					cout << "您输入的有误，请检查后重新输入！" << endl;
				}
			}

			int age = 0;
			cout << "请输入年龄：" << endl;
			cin >> age;
			aaa->personArr[aaa->person_size].age = age;

			string phonenumber;
			cout << "请输入电话：" << endl;
			cin >> phonenumber;
			aaa->personArr[aaa->person_size].phonenumber = phonenumber;

			string address;
			cout << "请输入地址：" << endl;
			cin >> address;
			aaa->personArr[aaa->person_size].address = address;

			aaa->person_size++;
			cout << "添加联系人成功！" << endl;
	}
	else
	{
		cout << "联系人已满，请删除部分联系人再添加！" << endl;
	
	}
	system("pause");
	system("cls");
}

显示联系人

void showperson(addressbook person)
{
	if (person.person_size == 0)
	{
		cout << "联系人列表为空" << endl;
	}
	for (int i = 0; i < person.person_size; i++)
	{
		cout << i + 1 << "." << "姓名：" << person, personArr[i].name << " "
			<< "性别：" << （person.personArr[i].sex == 1 ? "男"："女") << " "
			<< "年龄：" << person.personArr[i].age << " "
			<< "电话：" << person.personArr[i].phonenumber << " "
			<< "住址：" << person.pearsonArr[i].address << " " << endl;
	}
	system("pause");
	system("cls");
}

删除联系人

void deleteperson(addressbook * person)
	{
		string name;
		cout << "请输入您要删除的联系人姓名" << endl;
		cin >> name;
		int exist = isExist(person, name);
		if (exist != -1)
		{
			for (int i = exist; i < person->person_size; i++)
			{
				{
					person->personArr[i] = person->personArr[i + 1];

				}
				(person->person_size)--;
				cout << "删除成功！" << endl;

			}
		else
		{
			cout << "没有这个人！" << endl;

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

		}

查找联系人

void showperson(addressbook person)
{
	if (person.person_size == 0)
	{
		cout << "联系人列表为空" << endl;
	}
	for (int i = 0; i < person.person_size; i++)
	{
		cout << i + 1 << "." << "姓名：" << person, personArr[i].name << " "
			<< "性别：" << （person.personArr[i].sex == 1 ? "男"："女") << " "
			<< "年龄：" << person.personArr[i].age << " "
			<< "电话：" << person.personArr[i].phonenumber << " "
			<< "住址：" << person.pearsonArr[i].address << " " << endl;
	}
	system("pause");
	system("cls");

修改联系人

void modifyperson(addressbook * person)
		{
			string name;
			cout << "请输入要修改的联系人姓名：" << endl;
			cin >> name;
			int exist = isExist(person, name);
			if (exist != -1)
			{
				string modifyName;
				cout << "请输入修改好的名字：";
				cin >> modifyName;
				if (modifysex == 1 || modifysex == 2)
				{
					person->personArr[exist].name = modifyName;

					while (true)
					{
						int modifysex;
						cout << "请输入修改后的性别（1.男 2.女）：";
						cin >> modifysex;
						if (modifysex == 1 || modifysex == 2)
						{
							person->personArr[exist].sex = modifysex;
							break;

						}
						else
						{
							cout << "您应当输入1或者2，请重新输入" << endl;

						}
						int modifyAge;
						cout << "请输入修改后的年龄：";
						cin >> modifyAge;
						person->personArr[exist].age = modifyAge;

						string modifyPhone;
						cout << "请输入修改后的电话：";
						cin >> modifyPhone;
						person->personArr[exist].phonenumber = modifyPhone;

						string modifyAddress;
						cout << "请输入修改后的住址：";
						cin >> modifyAddress;
						person->personArr[exist].address = modifyAddress;

						cout << "修改成功" << endl;
					}
				else
				{
					cout << "没有查到这个名字的人，故无法修改" << endl;
				}
				system("pause");
				system("cls");
				}

清空联系人

void emptyperson(addressbook * person)
				{
					string ensure;
					cout << "您确定清空所有联系人吗，此操作不可逆，请谨慎，如需清空，请输入：我同意" << endl;
					cin >> ensure;
					if (ensure == "我同意")
					{
						person->person_size = 0;
						cout << "清空联系人成功" << endl;
					}
					else
					{
						cout << "撤销了清空联系人的操作" << endl;
					}
					system("pause");
					system("cls");
				}

退出系统

int isExist(addressbook* person, string name)
{
	for (int i = 0; i < person->person_size; i++)
	{
		if (person->personArr[i].name == name)
		{
			return i;
		}
		return -1;
	}
