1.职工管理系统的需求
本教程主要利用C++实现一个职工管理系统
公司职工分类：普通员工，经理，老板，显示信息时，需要显示职工的编号，职工姓名，职工岗位，以及职责。
普通员工的职责：完成经理交给的任务。
经理职责：完成老板交给的任务，并下发任务给员工。
老板职责:管理公司所有事物。
2.功能实现
2.1创建管理类
class Worker_Manger
{
public:
Worker_Manger();
//展示菜单
void Dispaly() ;
//退出系统
void ExitSystem();
//记录职工的人数
int M_EmpNum=0;
//职工数组指针
Worker ** M_EmpArray=0;
//添加职工
void Add_Emp();
//判断是否编号重复,姓名可能相同
bool If_Id_Repeat(int id);
//保存文件
void Save();
//判断文件是否为空
bool M_FileEmpty=0;
//统计文件中的人数
int Get_EmpNum();
//初始化员工
void init_Emp();
//显示职工
void Show_Emp();
//删除职工
void Delete_Emp();
//判断是否存在要查找的职工
int IsExit_Id(int id);//Id查找方式
int IsExit_Name(string name);//Name查找方式
string IsExit_Id_Name_choice(int cho);
//查找联系人
void Find_Emp_Name();
void Find_Emp_Id();
void Find_Emp();
//修改职工信息
void Modify();
//编号排序
void Sort_Emp();
//清空操作
void Clean_File();
//析构函数
~Worker_Manger();
};
2.2退出功能
void Worker_Manger::ExitSystem()
{
cout << "欢迎下次使用" << endl;
system("pause");
exit(0);
}
2.3增加联系人信息
oid Worker_Manger::Add_Emp()
{
cout << "请输入添加的职工数量：" << endl;
int addnum = 0;//保存用户的输入数量
cin >> addnum;
if (addnum > 0)
{
int newSize = this->M_EmpNum + addnum;//新空间人数=原来的人数+新增加人数
//开辟新空间
Worker ** newspace = new Worker * [newSize+4];
//拷贝原来空间的数据
if (this->M_EmpArray != NULL)
{
for (int i = 0; i < this->M_EmpNum;i++)
{
newspace[i] = this->M_EmpArray[i];
}
}
//添加新数据
for (int i = 0; i < addnum; i++)
{
int id;//职工编号
string name;//职工的姓名
int dSelect;//部门选择
cout << "请输入第" << i + 1 << "个职工编号：" << endl;
cin >>id;
//If_Id_Repeat(id);
while (If_Id_Repeat(id))
{
int cho = IsExit_Id(id);//Id查找方式
cout << "通讯录已经有相同的编号，请重新输入" << endl;
this->M_EmpArray[cho]->Showinformation();
cin >> id;
}
cout << "请输入第" << i + 1 << "个职工姓名：" << endl;
cin >> name;
cout << "请选择该职工的岗位：" << endl;
cout << "1.职员" << endl;
cout << "2.经理" << endl;
cout << "3.总裁" << endl;
cin >> dSelect;
Worker* worker = NULL;
switch (dSelect)
{
case 1:
worker = new Employee(id, name, 1);
break;
case 2:
worker = new Manager(id, name, 2);
break;
case 3:
worker = new Boss(id, name, 3);
break;
default:
break;
}
//将创建职工职责，保存到数组中
newspace[this->M_EmpNum + i] = worker;
}
//释放空间
delete[] this->M_EmpArray;
//更改新空间的指向
this->M_EmpArray = newspace;
//更新新空间的人数
this->M_EmpNum = newSize;
//更新职工不为空的情况标志
this->M_FileEmpty = false;
//提示添加成功
cout << "成功添加" << addnum << "名新职工" << endl;
//保存数据
this->Save();
}
else
{
cout << "输入有误" << endl;
}
system("pause");
system("cls");
}
2.4显示职工信息
void Worker_Manger::Show_Emp()
{
//判断文件是否为空
if (this->M_FileEmpty)
{
cout << "文件不存在或文件为空!" << endl;
}
else
{
for (int i = 0; i < M_EmpNum; i++)
{
//利用多态
this->M_EmpArray[i]->Showinformation();
}
}
//按任意键清屏
system("pause");
system("cls");
//Name查找方式
int Worker_Manger::IsExit_Name(string name)
{
int index = -1;
for (int i = 0; i < this->M_EmpNum; i++)
{
if (this->M_EmpArray[i]->M_name == name)
{
//找到
index = i;
break;
}
}
return index;
}
//Id查找方式
int Worker_Manger::IsExit_Id(int id)
{
int index = -1;
for (int i = 0; i < this->M_EmpNum; i++)
{
if (this->M_EmpArray[i]->M_id == id)
{
//找到
index = i;
break;
}
}
return index;
}
}
2.5删除离职职工
void Worker_Manger::Delete_Emp()
{

cout << "1.通过姓名查找要删除的联系人" << endl;
cout << "2.通过编号查找要删除的联系人" << endl;
cin >> choose;
switch (choose)
{
case 1:

cout << "请输入要删除职工的姓名" << endl;
string name;
cin >> name;
int index = this->IsExit_Name(name);
if (index != -1)
{
string ch = IsExit_Id_Name_choice(index);
if (ch == "是")
{
for (int i = index; i < this->M_EmpNum - 1; i++)
{
this->M_EmpArray[i] = this->M_EmpArray[i + 1];
}
this->M_EmpNum--;
//数据同步更新文件当中
this->Save();
cout << "删除成功!" << endl;
}
else
{
cout << "取消成功" << endl;
break;
}
}

cout << "未找到此人，删除失败!" << endl;
break;
}
}
case 2:
