基础和派生中的构造函数 class

Constructor in base and derived class

程序可以运行,但我不确定构造函数有什么问题,因为每次程序运行时都会出现此错误 "warning: base class 'Alat' is uninitialized when used here to access 'Alat::ime' [-Wuninitialized]"。我想我从 base class 调用构造函数的方式有问题,但我不确定是什么问题。真的需要帮助,请提前 tnx。

#include <iostream>
#include <string>
using namespace std;

class Alat{
protected:
    string ime;
    int serBr;
    int cena;

public:   

    void setIme(string i);
    string getIme();

    void setSerBr(int sb);
    int getSerBr();

    void setCena(int c);
    int getCena();

    Alat();
    Alat(string i, int sb, int c)
    :ime(i),
     serBr(sb),
     cena(c)
    {}

    void info();


    ~Alat();
};

#include "Alat.h"

class Rucni : public Alat{
protected:
    int minGodKor;

public:    

    Rucni():Alat(ime, serBr, cena)  //I think here is problem, is it wrong called?    
    {}

    int getminGodKor();
    void setminGodKor(int min);

    void info();

    ~Rucni();

};

让子默认构造函数调用默认的父构造函数,并创建另一个带参数的子构造函数调用相应的父构造函数:

#include <string>

using std::string;


class Alat
{
protected:
    string ime;
    int serBr;
    int cena;

public:   

    void setIme(string i)
    {
        ime = i;
    }

    string getIme()
    {
        return ime;
    }

    void setSerBr(int sb)
    {
        serBr = sb;
    }

    int getSerBr()
    {
        return serBr;
    }

    void setCena(int c)
    {
        cena = c;
    }

    int getCena()
    {
        return cena;
    }

    Alat()
    {
    }

    Alat(string i, int sb, int c) : ime(i), serBr(sb), cena(c)
    {
    }

    ~Alat()
    {
    }
};


class Rucni : public Alat
{
protected:
    int minGodKor;

public:    

    Rucni() // implicit call of the parent default constructor
    {
    }

    Rucni(string i, int sb, int c) : Alat(i, sb, c) // explicit call of the corresponding parent constructor
    {
    }

    int getminGodKor()
    {
        return minGodKor;
    }

    void setminGodKor(int min)
    {
        minGodKor = min;
    }

    ~Rucni()
    {
    }
};


int main()
{
    Rucni r;

    return 0;
}
