push back on object

[julof26]

Hi again!

I have a question!

I have this class

class Ziak{
      private:
              string Meno;
              int Cislo, Rocnik;
              vector<int> Kurzy;
      public:
             void Uprav(string NMeno, int NCislo, int NRocnik){
                  Meno=NMeno; Cislo=NCislo; Rocnik=NRocnik;
             }
             int ZistiCislo(){  return Cislo;  }
             int ZistiPocetKurzov(){  return Kurzy.size()-1;  }
             int ZistiCisloKurzu(int i){  return Kurzy[i];  }
};

then in the next class this:

class Spojenie{
      private:
              vector<Ziak> ziak;
              vector<Kurz> kurz;
      public:
             bool AddZiak(string Meno, int Rocnik){
                          int ID=0;
                          . . .
                          ziak.push_back();
                          ziak[ziak.size()-1].Uprav(Meno, ID, Rocnik);
                          return true;
             }
};

Here ziak.push_back(); it is causing error cuz I dont know what I have to give there as arguments
Can someone help me please? :)

P.S.: Sorry for non-english names of variables :)

You need to push_back an instance of Ziak:

Ziak z;
ziak.push_back(z); // z will be copied!

yeah thanks

so if it is copied I can use the copy contructor insteda of Uprav function yes?

EDIT:

I do it like this

declared constructor

Ziak(string Nmeno, int NID, int NRocnik){
                 Meno=Nmeno; Cislo=NID; Rocnik=NRocnik;
}

and to class Spojenie add a block

{
Ziak z(Meno, ID, Rocnik);
ziak.push_back(z);
}
