c++ - “error:no matching function call to …”

我有这个错误。 “错误:没有匹配的函数来调用'Employee::Employee()'”。当我编写有关“教员类”的构造函数时，出现此错误。
您能帮我解决这个问题吗？我求助:(。
还有2个类(class)。 “日期”和“人”。 “人员”是“雇员”的父类(super class)。

员工

 #ifndef GK_EMPLOYEE_H
 #define GK_EMPLOYEE_H
 #include "GK_Person.h"

 class Employee:public Person
{
public:

Employee(char* name,char* surname,char* sex,char* pob, Date* dob,Date* start,char* title,int salary,bool fulltime =true);// start refers to dynamic memory
//virtual ~Employee();
void SetTitle(char* title);
friend ostream& operator<<(ostream&,const Employee&);

friend class Faculty;
private:
char* m_title;
int m_salary;
bool m_fulltime;
Date* m_start;// date started working
};


#endif // GK_EMPLOYEE_H

员工文件

#include "GK_Employee.h"

Employee::Employee(char* name,char* surname,char* sex,char* pob, Date* dob,Date* start,char* title,int salary,bool fulltime/*=true*/){

m_name=name;
m_surname=surname;
m_sex=sex;
m_pob=pob;
m_dob=dob;
m_start=start;
m_title=title;
m_salary=salary;
m_fulltime=fulltime;

}

void Employee::SetTitle(char* title){
m_title = title;
}

学院

  #ifndef GK_FACULTY_H
  #define GK_FACULTY_H
  #include "GK_Employee.h"

 class Faculty :public Employee
{
public:
Faculty(char* name,char* surname,char* sex,char* pob, Date* dob,Date* start,int level,int salary,Date* dolat,bool fulltime = true);
//virtual ~Faculty();
char GetType() const{return'F';}
void Promote(Date* dt);
friend ostream& operator<<(ostream&,const Faculty&);

 private:
 Date* m_dolat;// date of last academic title owned
int m_level;// 0 for Dr., 1 for Ass.Prof.Dr., 2 for Assoc.Prof.Dr. and 3 for Prof.Dr.
};


 #endif // GK_FACULTY_H

教员

#include "GK_Faculty.h"

Faculty::Faculty(char* name,char* surname,char* sex,char* pob, Date* dob,Date* start,int level,int salary,Date* dolat,bool fulltime/*= true*/){

}

最佳答案

由于Faculty源自Employee，因此您需要在Employee构造函数中初始化Faculty的成员。这必须通过调用Employee的构造函数来完成。如果Employee具有默认构造函数(即不带任何参数的构造函数)，则编译器将为您隐式执行此操作。但是Employee仅定义以下构造函数:

Employee(char* name,char* surname,char* sex,char* pob, Date* dob,Date* start,char* title,int salary,bool fulltime =true);// start refers to dynamic memory

编译器无法确定将哪些参数传递给此 Controller ，因此您需要自己从Faculty Controller 内部调用它。像这样:

#include "GK_Faculty.h"

Faculty::Faculty(char* name,char* surname,char* sex,char* pob, Date* dob,Date* start,int level,int salary,Date* dolat,bool fulltime/*= true*/)
: Employee(name,surname,sex,pob,dob,start,"mytitle",salary,fulltime)
{

}
