鏈表訪問私有成員錯誤C2248

Question

我做了一個鏈表類員工在這裏我的代碼：

Node.cpp

#include "EmpNode.h" 

    EmpNode::EmpNode(int id, string name){ 

     emp.id = id; 
     emp.name = name; 
     next = NULL; 
    } 

List.cpp

#include "List.h" 
#include "Header.h" 

bool ListOfEmp::insertEmp(int id, string name){ 

    EmpNode *newNode = new EmpNode(id, name); 

    if (!newNode){ 
     return false; // Failure 
    } 
    else{ 
     newNode->next = head; 
     head = newNode; 
     return true; // Success 
    } 
} 

bool ListOfEmp::findEmp(int id, const Employee &emp) const{ 
    EmpNode *currentNode = head; 

    while (currentNode != 0){ 
     if (currentNode->emp.id == id){ 
      emp = currentNode->emp; 
      return true; 
     } 
     currentNode = currentNode->next; 
    } 
    return false; 
} 

Node.h

#pragma once 
// My Node 
class EmpNode { 
    friend class ListOfEmp; 
public: 
    EmpNode(int id, string name); 

private: 
    Employee emp; 
    EmpNode *next; 
}; 

List.h

#pragma once 
// My List of Nodes 
class ListOfEmp { 

public: 
    ListOfEmp(); 
    ~ListOfEmp(); 
    bool findEmp(int id, const Employee &emp) const; 
    bool insertEmp(int id, string name); 

private: 
    EmpNode *head; 
}; 

錯誤1錯誤C2248：「員工:: ID」：不能訪問類中聲明「員工」 \\ 22 1 LinkedList的

我想你想使用它的構造函數初始化emp成員私有成員並且您要查找的是

EmpNode::EmpNode(int id, string name) 
    : emp(id, name), 
     next(NULL) 
{ 
}
