我的代码中不断出现各种错误，有人可以通过他们的编译器运行它并帮助我解决它们吗？我修复了一些，我现在得到的一个是没有匹配的函数来调用 'classRooms::ClassRooms(std::string&, int&, .....

//classRoom.h 

#ifndef CLASSROOMS_H
#define CLASSROOMS_H

#include <iostream>
#include <string>
#include "ClassRooms.h"

using namespace std;

class ClassRooms
{
public:

    ClassRooms(int nRooms=100)
        : numRooms(0), rooms(new ClassRooms[nRooms]) { }
    ~ClassRooms()
    {
        delete [] rooms;
    }
    void addRoom(const ClassRooms& cr)
    {
        rooms[numRooms++] = cr;
    }
    string findRoom(int seats)const;
    int getSeats();
    double getAreaPerSeat();
   string getRoomNumber();
private:
    int numRooms;
    ClassRooms *rooms;
    int numSeats;
    double length, width;

};

#endif //CLASSROOMS_H

您没有Classrooms采用 a 的构造函数，(string, int, double, double)因此，这ClassRooms(roomNum, seats, len, wid)是一个错误。您可以轻松地添加适当的构造函数Classrooms。

ClassRooms(string roomNum, int seats, double len, double wid){
    //do something
}
