C++面向对象入门~构造函数编译不通过

一个简单的面向对象入门，在codeblock上，构造函数的参数编译失败

#include <iostream>using namespace std;class Building{protected:    string name;    int floorNumroomAmount;    float wholeArea;public:    Building(string nint fint rfloat w)    {        this->name=n;        this->floorNum=f;        this->roomAmount=r;        this->wholeArea=w;    }    void display()    {        cout<<""建筑物名称：""<<name<<endl;        cout<<""层数：""<<floorNum<<endl;        cout<<""教室（房间）数""<<roomAmount<<endl;        cout<<""总面积""<<wholeArea<<endl;    }};class TeachBuilding:protected Building{protected:    string func;public:    TeachBuilding(string nint fint rfloat wstring func):Building(string nint fint rfloat w)    {        this->func=func;    }    void display()    {        Building::display();        cout<<""建筑物功能：""<<func<<endl;    }};class DormBuilding :public Building{protected:    int people;public:    DormBuilding(string nint fint rfloat wint people):Building(string nint fint rfloat w)    {        this->people=people;    }    void display()    {        Building::display();        cout<<""可容纳人数：""<<people<<endl;    }};int main(){    TeachBuilding TB(""5号楼""5404000机房"");    TB.display();    cout<<endl;    DormBuilding DB(""宿舍C3""81401352523);    DB.display();    return 0;}

解决方案

 #include <iostream>using namespace std;class Building{protected:    string name;    int floorNumroomAmount;    float wholeArea;public:    Building(string nint fint rfloat w)    {        this->name=n;        this->floorNum=f;        this->roomAmount=r;        this->wholeArea=w;    }    void display()    {        cout<<""建筑物名称：""<<name<<endl;        cout<<""层数：""<<floorNum<<endl;        cout<<""教室（房间）数""<<roomAmount<<endl;        cout<<""总面积""<<wholeArea<<endl;    }};class TeachBuilding:protected Building{protected:    string func;public:    TeachBuilding(string nint fint rfloat wstring func):Building(nfrw) //修改    {        this->func=func;    }    void display()    {        Building::display();        cout<<""建筑物功能：""<<func<<endl;    }};class DormBuilding :public Building{protected:    int people;public:    DormBuilding(string nint fint rfloat wint people):Building(nfrw) //修改    {        this->people=people;    }    void display()    {        Building::display();        cout<<""可容纳人数：""<<people<<endl;    }};int main(){    TeachBuilding TB(""5号楼""5404000机房"");    TB.display();    cout<<endl;    DormBuilding DB(""宿舍C3""81401352523);    DB.display();    return 0;}

解决方案二：
建筑物名称：5号楼
层数：5
教室（房间）数40
总面积4000
建筑物功能：机房

建筑物名称：宿舍C3
层数：8
教室（房间）数140
总面积1352
可容纳人数：523

解决方案三：
building类中的缺少初始构造函数

就是你应该有无参数传入的构造函数

解决方案四：
你的程序中有：string name;所以你要加上头文件#include
其次，你的这句代码TeachBuilding(string nint fint rfloat wstring func):Building(nfrw)。有些问题

解决方案五：
没有错误提示吗？错误提前？？？？

解决方案六：
string头文件都没加
