我正在尝试为我创建的一些类测试我的代码,但是在尝试编译时遇到了一些困难。我有三个类和一个主要类。第一类是人的类(class),第二和第三类是从人派生的学生和教师。
这是Person.h类的内容:

#ifndef Person_H
#define Person_H
#include <string>

using namespace std;

class Person
{
protected:
long id;
string name;
string email;
string address;
string dateOfBirth;
string gender;

public:
Person(long pId);
Person(long pId, string pName, string pEmail, string pAddress, string pDateOfBirth, string pGender);
void print() const;
};
#endif

这是我的Person.C
#include <iostream>
#include "Person.h"
using namespace std;

Person::Person(long pId)
{
id = pId;
name = "Nothing";
email = "Nothing";
address = "Nothing";
dateOfBirth = "Nothing";
gender = "Nothing";
}

Person::Person(long pId, string pName, string pEmail, string pAddress, string pDateOfBirth, string pGender)
{
id = pId;
name = pName;
email = pEmail;
address = pAddress;
dateOfBirth = pDateOfBirth;
gender = pGender;
}

void Person::print() const
{
cout << "ID: " << id << endl;
cout << "Name: " << name << endl;
cout << "Email: " << email << endl;
cout << "Address: " << address << endl;
cout << "Date of Birth: " << dateOfBirth << endl;
cout << "Gender: " << gender << endl;
}

这是Student.h
#ifndef Student_H
#define Student_H
#include<string>
#include <vector>
#include "Person.h"
#include "Course.h"
using namespace std;

class Student:public Person
{
protected:
int yearOfStudy;
string major;
long advisorId;
vector <Course> coursesTaken;
static long nextStId;

public:
Student();
Student(string sName, string sEmail, string sAddress, string sDateOfBirth, string sG\
ender, int sYearOfStudy, string sMajor, long sAdvistorId);
void print() const;
};
#endif

这是Student.C
#include<iostream>
#include "Student.h"
using namespace std;

long Student::nextStId = 500;

Student::Student():Person(nextStId)
{
yearOfStudy = 0;
major = " ";
advisorId = 0;
}

Student::Student(string sName, string sEmail, string sAddress, string sDateOfBirth, st\
ring sGender, int sYearOfStudy, string sMajor, long sAdvisorId):Person(nextStId, sName\
, sEmail, sAddress,sDateOfBirth, sGender)
{
yearOfStudy = sYearOfStudy;
major = sMajor;
advisorId = sAdvisorId;
}

void Student::print() const
{
Person::print();
cout << "Year of study: " << yearOfStudy << endl;
cout << "Major: " << major << endl;
cout << "Advisor ID: " << advisorId << endl;
}

现在我的主要任务是:
#include <iostream>
#include <string>
#include "Faculty.h"
#include "Student.h"
#include "Person.h"
using namespace std;

int main()
{
Student test1;
Faculty test2;
test1.print();
cout << endl;
test2.print();

return 0;
}

我尝试编译时收到的错误是:
 g++ Assignment3.C Person.C Student.C Faculty.C
Assignment3.C: In function âint main()â:
Assignment3.C:10: error: âStudentâ was not declared in this scope
Assignment3.C:10: error: expected `;' before âtest1â
Assignment3.C:12: error: âtest1â was not declared in this scope

我不明白为什么会给我这个错误。我的教师类似乎运行得很好。有人可以帮忙吗!

最佳答案

我不是专家,但在test1之后您不需要()吗?像学生测验1();我知道这与错误无关,但是您可以检查。
