我要創建C++中的小型控制檯應用程序，這將做到以下幾點：在第二個對象的數組存儲對象
創建類話題爲接下來的屬性：對象的名字，學生和陣列的數量的參加該科目的學生。之後，創建一個名爲學生姓名的學生作爲屬性。在主文件中統計每個主題有多少重複名稱。
我在這裏幾乎沒有問題。首先，我不知道如何初始化Subject.h文件中的數組。其次是如何實際將Student對象放入Subject對象中，並最終比較名稱。
想輸出什麼我看起來像：
在subjectA重複的名稱是：邁克爾。
subjectB重複的名字是：Nicholas，John。
其中subjectA和subjectB應該被稱爲C++和C。
這是我的代碼到目前爲止（我搜索了一兩個關於我的這個問題，但我只是找不到正確的答案/例子）。
注：我包括所有這些文件的澄清。
Subject.h
#include <string>
#include <iostream>
using namespace std;
/*
* I should also have an array named `arrayOfStudents`
* which should store all students who are attending
* that Subject.
*/
class Subject
{
public:
Subject();
Subject(Subject &subject);
Subject(string nameOfSubject, int numberOfStudents);
~Subject();
const string getNameOfSubject();
const int getNumberOfStudents();
void setNameOfSubject(string nameOfSubject);
void setNumberOfStudents(int numberOfStudents);
void print();
private:
string nameOfSubject;
int numberOfStudents;
};
Subject.cpp
#include <iostream>
#include "Subject.h"
using namespace std;
Subject::Subject()
{
}
Subject::Subject(string nameOfSubject, int numberOfStudents)
{
this->nameOfSubject = nameOfSubject;
this->numberOfStudents = numberOfStudents;
}
Subject::Subject(Subject &Subject) : nameOfSubject(Subject.getNameOfSubject()), numberOfStudents(Subject.getNumberOfStudents())
{
}
Subject::~Subject()
{
cout << "Object is destroyed" << endl;
}
const string Subject::getNameOfSubject()
{
return nameOfSubject;
}
const int Subject::getNumberOfStudents()
{
return numberOfStudents;
}
void Subject::setNameOfSubject(string nameOfSubject)
{
nameOfSubject = this->nameOfSubject;
}
void Subject::setNumberOfStudents(int numberOfStudents)
{
numberOfStudents = this->numberOfStudents;
}
void Subject::print()
{
cout << "Subject: " << nameOfSubject << " :: Number of students: " << numberOfStudents << endl;
}
Student.h
#include <string>
#include <iostream>
using namespace std;
class Student
{
public:
Student();
Student(Student &student);
Student(string name, string surname);
~Student();
const string getName();
const string getSurname();
void setName(string name);
void setSurname(string surname);
void print();
private:
string name;
string surname;
};
Student.cpp
#include <iostream>
#include "Student.h"
using namespace std;
Student::Student()
{
}
Student::Student(string name, string surname)
{
this->name = name;
this->surname = surname;
}
Student::Student(Student &student) : name(student.getName()), surname(student.getSurname())
{
}
Student::~Student()
{
cout << "Object is destroyed" << endl;
}
const string Student::getName()
{

const string Student::getSurname()

void Student::setName(string name)

}
void Student::setSurname(string surname)
{
surname = this->surname;
}
void Student::print()
{
cout << "Student: " << name << " " << surname << endl;
}
Main.cpp的
#include <iostream>
#include "Subject.h"
#include "Student.h"
using namespace std;
int main()
{
/*
* First three students should attend first Subject
* while other four the second Subject.
* Also note that only names matter and not surnames.
*/
Student stA("Michael", "Doe");
Student stB("Michael", "Doe");
Student stC("Thomas", "Doe");
Student stD("Nicholas", "Doe");
Student stE("Nicholas", "Doe");
Student stF("John", "Doe");
Student stG("John", "Doe");
Subject subjectA("C++", 3);
Subject subjectB("C", 4);
return 0;
}
'nameOfSubject = this-> nameOfSubject;'在'setNameOfSubject'和其他的後面。但是我沒有看到有關打印「重複名稱......」的任何代碼，所以，誰知道？ –
