C++ 对象链表

Question

我有一个类，它的对象必须添加到链表中。对象仅在非成员函数中创建。我不得不承认，链接列表对我来说毫无意义，是的，我已经阅读了这个论坛上的其他问题，但仍然无法弄清楚。

我将如何进行 1. 创建这个链表 2. 每次创建一个对象时都向这个列表添加一个对象 3. 能够删除列表中的每个节点？

这是我的课：

class ShirtOrder
{
    friend ostream& operator<<(ostream &os, const ShirtOrder &rhsObj);

private:
    // the data members below are required (you may change identifiers)
    // there is no need for additional data members
    int orderYear, orderMonth, orderDay;
    char printMethod; // 's', 'i', or 'e'
    string message;
    int mediums; // number of medium shirts ordered
    int larges; // number of large shirts ordered
    int xls; // number of XL shirts ordered
    string shirtColor;
    string inkColor;
    string orderID;
    string region;
    string nameAndEmail;

    ShirtOrder* next; // new for P5

public:
    ShirtOrder(); // default constructor

    ShirtOrder(int orderYear, int orderMonth, int orderDay,
               char printMethod, string message, int mediums, int larges, int xls,
               string shirtColor, string inkColor, string orderID,
               string region, string nameAndEmail,
               ShirtOrder *soPtr = NULL);

    ShirtOrder(const ShirtOrder &otherObj);

    ~ShirtOrder(); // destructor                      // New for P5 (may not be in-line)

    ShirtOrder* getNext() const {return next;}        // New for P5 (may be in-line)

    void setNext(ShirtOrder* soPtr) {next = soPtr;}   // New for P5 (may be in-line)

    double getBlankCost() const;
    double getPrintingCost() const;
    double getTotalCost() const;

    int    getLetterCount() const;
    char   getPrintMethod() const {return printMethod;}
    int    getOrderYear() const {return orderYear;}
    int    getOrderMonth() const {return orderMonth;}
    int    getOrderDay() const {return orderDay;}
    int    getMediums() const {return mediums;}
    int    getLarges() const {return larges;}
    int    getXls() const{return xls;}

    string getShirtColor() const {return shirtColor;}
    string getInkColor() const {return inkColor;}
    string getOrderID() const {return orderID;}
    string getRegion() const {return region;}
    string getNameAndEmail() const {return nameAndEmail;}
    string getMessage() const {return message;}

    void  setOrderYear (int orderYear) {this->orderYear = orderYear;}
    void  setOrderMonth (int orderMonth) {this->orderMonth = orderMonth;}
    void  setOrderDay (int orderDay) {this->orderDay = orderDay;}
    void  setPrintMethod (char printMethod) {this->printMethod = printMethod;}
    void  setMessage (string message) {this->message = message; }
    void  setMediums (int mediums) {this->mediums = mediums;}
    void  setLarges (int larges) {this->larges = larges;}
    void  setXls (int xls) {this->xls = xls;}
    void  setShirtColor (string shirtColor) {this->shirtColor = shirtColor;}
    void  setInkColor (string inkColor) {this->inkColor = inkColor;}
    void  setOrderID (string orderID) {this->orderID = orderID;}
    void  setRegion (string region) {this->region = region;}
    void  setNameAndEmail (string nameAndEmail) {this->nameAndEmail = nameAndEmail;}

};

所以说这个类的一个对象是在一个非成员函数中创建的。如何创建此类对象的列表，并将每个对象添加到列表的末尾？谢谢！

在你的私人领域创建一个std::lib<dataType> mylist;

然后你只需插入你想要的项目。 mylist.insert(whateverItem);

这有帮助吗？
