关于结构选择的模板错误

我的结构有问题......或类似的东西。我有2个数组,其中一个被定义为Array <Student> DBst,一个Array <Assignment> DBas。事情是错过了,因为我的一个函数(模板形式)弹出一个错误它告诉我Class Assignment没有函数setStudent(...)但是我不知道为什么它会读取我的结构{ {1}}作为Assigment对象的集合。

Domain.h:

DBst

或者Controller.h:

template <class T>
void addStudent(int a, int b, std::string c,Array <T> &A){
    A.M[a].setStudent(a,b,c);
    cout<<"here";
}

Menuc.cpp:

template <class T1>
void _addStudent(Array <T1> &A){
    int a,b;
    string c;
    cout<<"Enter ID:"<<endl;
    cin>>a;
    cout<<"Enter Group:"<<endl;
    cin>>b;
    cout<<"Enter Name:"<<endl;
    cin>>c;

    addStudent(a,b,c,A);
}

Menu.h:

void Menu::mainMenu(Array <Student> &DBst,Array <Assignment> &DBas){
showMainMenu();
int ret = Menu::intInputHandler();

switch(ret){
case 1:studentMenu(DBst,DBas);break;
case 2:assignmentMenu(DBas,DBst);break;
case 3:statsMenu(DBst,DBas);break;
case 4:_printAll(DBst,DBas);break;
case 0:break;
default:cout<<"Wrong option selected!";break;
}
Menu::mainMenu(DBst,DBas);

    void Menu::studentMenu(Array <Student> &DBst,Array <Assignment> &DBas){
    showStudentMenu();
    int ret = Menu::intInputHandler();

    switch(ret){
    case 1:_addStudent(DBst);break;
    case 2:_removeStudent(DBst);break;
    case 3:_editStudent(DBst);break;
    case 4:_printStudent(DBst);break;
    case 5:_printAllStud(DBst);break;
    case 6:_searchByID(DBst);break;
    case 0:mainMenu(DBst,DBas);break;
    default:cout<<"Wrong option selected!";break;
    }
    Menu::studentMenu(DBst,DBas);
}

Student.cpp:

class Menu{

    public:
        string stringInputHandler();
        int intInputHandler();
        void mainMenu(Array <Student> &,Array <Assignment> &);
        void studentMenu(Array <Student> &,Array <Assignment> &);
        void assignmentMenu(Array <Assignment> &,Array <Student> &);
        void statsMenu(Array <Student> &,Array <Assignment> &);
};

我得到的错误是休息:

void Student::setStudent(int a,int b,string c){
this->ID = a;
    this->group = b;
    this->name = c;
}

编辑:

D:\c++\Begin\Lab6-8_UML/Domain.h:70:2: error: 'class Assignment'
                                       has no member named 'setStudent'`

1 个答案:

答案 0 :(得分:1)

它在您提供的代码中不可见,但我怀疑您使用addStudent<T>参数(最后一个)调用某个Array<Assignment>函数并且Assignment类没有setStudent方法。
