c++ - 'SystimaDieythynsis' & 'Mihani' 没有命名类型

Question

标题说明了问题，为什么编译不通过？

class Vehicle {


private:

    char* idioktitis,arKykloforias;
    int etosKat;
    SystimaDieythynsis sysdief;
    Mihani eng;

};

class Mihani {

private:

    int kyvismos,ippodynami;
public:

    void leitourgia();
    void kinisi();
    void svysimo();
};

void SystimaDieythynsis::vazeiEmpros(){

    cout << "Bazei Empros";
}

void SystimaDieythynsis::svynei(){

    cout << "Svynei";
}

void SystimaDieythynsis::striveiAristera(){

    cout << "Strivei Aristera";
}

void SystimaDieythynsis::striveiDexia(){

    cout << "Strivei Dexia";
}

void Mihani::leitourgia(){

    cout << "Leitourgia Mhxanhs";

}

void Mihani::kinisi(){

    cout << "Kinhsh Mhxanhs";

}

void Mihani::svysimo(){

    cout << "Svhsimo Mhxanhs";

}

int main(int argc, char *argv[])

{

   system("PAUSE");

   return EXIT_SUCCESS;

}

Answer 1

您需要为 SystimaDieythynsis 添加一个类定义，并将其和 Mihani 的类定义放在 Vehicle 的类定义之前。像这样:

class Mihani { 
    // ...
};

class SystimaDieythynsis {
    // ...
};

class Vehicle {
    // ...
};

// insert function definitions here
