一想到“管理系统”，咱们脑海里通常浮现四个字，增查删改。这也是必不可少的局部。
我先把这个零碎我要实现的局部列举进去（当然，我的思路有很多有余，恳请大佬斧正，批评，不胜感激）
cout << "***********1. 增加联系人 **********" << 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. 批改联系人 **********" << endl;
cout << "***********6. 清空联系人 *********" << endl;
cout << "***********0. 退出零碎 ***********" << endl;（备注：退出也是其中一个性能哦）
首先，构建构造体变量
#define MAX 1000
struct person
{
string name;
int sex{ };
int age{ };
string phonenumber;
string address;
};
struct addressbook
{struct person personArr[MAX];
int person_size{};增加联系人
void addPerson(addressbook* aaa) // 增加联系人模块
{if (aaa->person_size < MAX)
{
string name;
cout << "请输出姓名：" << endl;
cin >> name;
aaa->personArr[aaa->person_size].name = name;
int sex;
cout << "请输出性别对应序号：（1-- 男 2-- 女 )" << endl;
while (true)
{
cin >> sex;
if ((sex == 1) || (sex == 2))
{aaa->personArr[aaa->person_size].sex = sex;
break;
}
else
{cout << "您输出的有误，请查看后从新输出！" << endl;}
}
int age = 0;
cout << "请输出年龄：" << endl;
cin >> age;
aaa->personArr[aaa->person_size].age = age;
string phonenumber;
cout << "请输出电话：" << endl;
cin >> phonenumber;
aaa->personArr[aaa->person_size].phonenumber = phonenumber;
string address;
cout << "请输出地址：" << endl;
cin >> address;
aaa->personArr[aaa->person_size].address = address;
aaa->person_size++;
cout << "增加联系人胜利！" << endl;
}
else
{cout << "联系人已满，请删除局部联系人再增加！" << 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 << "删除胜利！" << 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");批改联系人
void modifyperson(addressbook * person)
{
string name;
cout << "请输出要批改的联系人姓名：" << endl;
cin >> name;
int exist = isExist(person, name);
if (exist != -1)
{
string modifyName;
cout << "请输出批改好的名字：";
cin >> modifyName;
if (modifysex == 1 || modifysex == 2)
{person->personArr[exist].name = modifyName;
while (true)
{
int modifysex;
cout << "请输出批改后的性别（1. 男 2. 女）：";
cin >> modifysex;
if (modifysex == 1 || modifysex == 2)
{person->personArr[exist].sex = modifysex;
break;
}
else
{cout << "您该当输出 1 或者 2，请从新输出" << endl;}
int modifyAge;
cout << "请输出批改后的年龄：";
cin >> modifyAge;
person->personArr[exist].age = modifyAge;
string modifyPhone;
cout << "请输出批改后的电话：";
cin >> modifyPhone;
person->personArr[exist].phonenumber = modifyPhone;
string modifyAddress;
cout << "请输出批改后的住址：";
cin >> modifyAddress;
person->personArr[exist].address = modifyAddress;
cout << "批改胜利" << endl;
}
else
{cout << "没有查到这个名字的人，故无奈批改" << 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，请审慎，如需清空，请输出：我批准" << endl;
cin >> ensure;
if (ensure == "我批准")
{
person->person_size = 0;
cout << "清空联系人胜利" << endl;
}
else
{cout << "撤销了清空联系人的操作" << endl;}
system("pause");
system("cls");
}退出零碎
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;
