c++ - 没有在类 'void StringSet::removeALL()' 中声明的 'StringSet' 成员函数

Question

我已经检查了其他类似的问题，但我仍然无法摆脱这个问题。我试图同时拥有公共(public)和私有(private)功能。

我的类(class)有一个 removeALL 函数:

类减法

#ifndef STRINGSET_H
#define STRINGSET_H
#include <iostream>
#include <string>
#include "StringNode.h"
using namespace std;

class StringSet
{
    public:
        // Constructor: creates an empty set.
        StringSet();

        // Destructor.
        ~StringSet();

        // Returns the number of elements in the set.
        int size();

        // Inserts 'element' into the set. If 'element' is contained in the
        // set, this operation has no effect.
        void insert(string element);

        // Removes 'element' from the set. If 'element' is not in the set, this
        // operation has no effect.
        void remove(string element);

        // Returns true if and only if 'element' is a member of the set.
        bool contains(string element);



        // A friend function for writing the contents of the set to an output stream.
        friend ostream& operator <<(ostream& outs, const StringSet& set);



    private:
        void removeAll();
        int fixing (string element);

        NodePtr head; // pointer to the head of the linked list
};

#endif // STRINGSET_H

但是当我尝试在 cpp 文件中创建函数时，我得到错误:没有在类“StringSet”中声明的“void StringSet::removeALL()”成员函数

删除cpp中的所有函数和头文件

#include <iostream>
#include <string>
#include "StringSet.h"

using namespace std;

void StringSet::removeALL()
{
     if(head == NULL){
        cout << "The list is empty" << endl;
        return;
    }

    while (NodePtr temp = head)
    {
        head = temp->getLink();
        delete temp;
    }

}

int StringSet::fixing(string element)
{
    int temp = 0;

    if(((element[0] == 'n') || (element[0] == 'N')) && ((element[1] == 'o') || (element[1] == 'O'))
       && ((element[2] == 't') || (element[2] == 'T')))
    {
        element.erase(0,3);
        remove(element);
        element.clear();
        temp = 1;
        return temp;

    }
    else return temp;
}

有人有解决办法吗？提前致谢!

C++ 区分大小写。 removeAll 和 removeALL 是不同的东西。
