结合C++特性(类模板/函数模板，STL的list)实现简单员工表示例
个人cpp作业练习，综合构造函数、析构函数、重载运算符等写一个员工类和员工表类，可借鉴思路，禁止照搬
1.原始版本
#include 程序输出：
2.类模板/函数模板 （用T替换员工表类的员工类数组）
#include 程序输出如上
3.STL list<> （替换员工表类的员工类数组）
#include
using namespace std;
class Employee{
public :
Employee(){
}
//重载<<便于显示输出员工信息
Employee(int id,string name,string sex,int age,string department):
id(id),name(name),sex(sex),age(age),department(department){
}
Employee(const Employee& employee){
this->id = employee.id;
this->name = employee.name;
this->sex = employee.sex;
this->age = employee.age;
this->sex = employee.sex;
this->department = employee.department;
}
friend ostream & operator<<( ostream & os,const Employee & employee);
void setName(string name){
this->name = name;}
string getName() {
return this->name;}
void setSex(string sex){
this->sex = sex;}
string getSex(){
return this->sex;}
void setDepartment(string department){
this->department = department;}
string getDepartment() {
return this->department;}
void setAge(int age){
this->age = age;}
int getAge() {
return this->age;}
void setId(int id){
this->id = id;}
int getId() {
return this->id;}
private :
int id;
string name;
string sex;
int age;
string department;
};
ostream & operator<<( ostream & os,const Employee & employee){
os<<"id="<<employee.id<<" name="<<employee.name<<" sex="<<employee.sex<<" age="<<employee.age
<<" department="<<employee.department<<endl;
return os;
}
class EmployeeList{
public:
//动态数组
EmployeeList(){
}
EmployeeList(int size){
eList = list<Employee>(size);}
~EmployeeList() {
}
void add(Employee employee) {
//添加员工
eList.push_back(employee);
}
int query_num(){
//查询员工人数
return eList.size();
}
void show_id(int id){
//通过id号查询显示员工信息
if (id<=0||id>eList.size()) {
cout<<"员工不存在!"<<endl;}
else {
int i=0;
list<Employee>::iterator it=eList.begin();
for(it;i<id;it++,i++){
if(i==id-1)
cout<<*(it); //重载Employee的<<进行输出
}
}
}
void dismiss(int id){
//通过id删除某员工信息
if(id<=0||id>eList.size()) {
cout<<"员工不存在!"<<endl;}
else {
int i = 0;
list<Employee>::iterator it=eList.begin();
for(it;i<id;it++,i++){
if(i==id-1)
eList.erase(it);
}
}
}
void update(int id,Employee &ee){
//通过id更新员工信息
int i=0;
list<Employee>::iterator it=eList.begin();
for(it;i<id;it++,i++){
if(i == id-1){
eList.insert(it,ee);
eList.erase(it);
}
}
}
private:
list<Employee> eList; //员工表
};
int main(){
EmployeeList list(0);//创建空员工表
Employee employee1(1,"林浩","男",18,"开发部");
Employee employee2(2,"文雅","女",18,"销售部");
Employee employee3(1,"李强","男",20,"开发部");
Employee tempEmployee = employee3;//拷贝employee3员工信息
list.add(employee1);
list.add(employee2);
list.add(employee3);
cout<<"现有员工数量:"<<list.query_num()<<endl;
list.show_id(2);//查询employee2员工信息
list.dismiss(2);//解雇employee2员工
cout<<"删除后..."<<endl;
cout<<"现有员工数量:"<<list.query_num()<<endl;
list.show_id(1);//查询employee1员工信息
list.update(1,tempEmployee);//更新employee1员工信息
cout<<"更新后..."<<endl;
list.show_id(1);//查询employee1员工信息
return 0;
}
程序输出如上
