C ++繼承沒有枚舉

Question

我試圖找出基本的繼承。 但是我似乎無法獲得枚舉。 它只是以笑臉回應而已。

老實說，我不知道我在做什么錯，所以恐怕我只需要把我所有的代碼扔給你。

#include <iostream>
#include <string>

using namespace std;

enum Discipline {
   COMPUTER_SCIENCE, Computer_SCIENCE_AND_INNOVATION
};

const string DISCIPLINE_STRINGS[2] = { "Computer Science",
   "Computer Science and Innovation",
};

class Person {
public:
    Person(){cout << "Person object created using the default Person constructor\n";};
    Person(const string& name, Discipline type){pName = name; pType = type;};
    ~Person(){cout << "Person object destroyed\n";};
    string pName;
    string pType;
};

class Faculty: public Person {
public:
    Faculty();
    Faculty(const string& name, Discipline type) {pName = name; pType = type; cout << "Faculty object created using the alternative Faculty constructor\n";};
    ~Faculty(){cout << "Faculty object destroyed!";};
    string getName(){return pName;};
    string getDepartment(){return pType;};
};

class Student: public Person {
public:
    Student();
    Student(const string& name, Discipline type) {pName = name; pType = type; cout << "Student object created using the alternative Student constructor\n";};
    ~Student(){cout << "Student object destroyed!";};
    string getMajor(){return pType;};
    string getName(){return pName;};
};



int main()
{
   Faculty prof("Name1", COMPUTER_SCIENCE);
   Student stu(" Name2", Computer_SCIENCE_AND_INNOVATION);

   cout << endl << "I, " << stu.getName() << ", am majoring in " << stu.getMajor() << "." << endl;
   cout << "I am taking CSI 240 with Prof. " << prof.getName() << ", who teaches "
        << prof.getDepartment() << " courses." << endl << endl;
   system ("pause");
   return 0;
}

Answer 1

您正在打印出枚舉而不是實際的字符串。 您應該使用枚舉索引到DISCIPLINE_STRINGS 。

設置類型字符串時，請執行以下操作： pType = DISCIPLINE_STRINGS[type]
