C++ construct issue -


i have problems following code:

    class osoba {        std::string imie;        std::string nazwisko;        std::string pesel;  public:        osoba(const std::string & im, const std::string & na, const std::string & pe);        std::string get_imie() const;        std::string get_nazwisko() const;        std::string get_pesel() const;  };    class pracownik : public osoba {        int liczba_godzin;      public:        pracownik(const std::string & im, const std::string & na, const std::string & pe, int liczba_godzin);        pracownik(const osoba & o, int liczba_godzin);        int podaj_liczbe_godzin() const;  };

i need write construct code. me? tried this, not work:

osoba::osoba(const std::string & im, const std::string & na, const std::string & pe):imie(im), nazwisko(na), pesel(pe){};  pracownik::pracownik(const std::string & im, const std::string & na, const std::string & pe, int liczba_godzin):imie(im), nazwisko(na),pesel(pe),liczba_godzin(liczba_godzin){}  pracownik::pracownik(const osoba & o, int liczba_godzin):osoba(o), liczba_godzin(liczba_godzin){};

@edtit errors logs below:

 c:\users\admin\desktop\projekt\main.cpp in constructor `pracownik::pracownik(const std::string&, const std::string&, const std::string&, int)':   5 c:\users\admin\desktop\projekt\main.cpp `std::string osoba::imie' private      37 c:\users\admin\desktop\projekt\main.cpp within context      37 c:\users\admin\desktop\projekt\main.cpp class `pracownik' not have field named `imie'      6 c:\users\admin\desktop\projekt\main.cpp `std::string osoba::nazwisko' private      37 c:\users\admin\desktop\projekt\main.cpp within context      37 c:\users\admin\desktop\projekt\main.cpp class `pracownik' not have field named `nazwisko'      7 c:\users\admin\desktop\projekt\main.cpp `std::string osoba::pesel' private      37 c:\users\admin\desktop\projekt\main.cpp within context      37 c:\users\admin\desktop\projekt\main.cpp class `pracownik' not have field named `pesel'      37 c:\users\admin\desktop\projekt\main.cpp no matching function call `osoba::osoba()'       note c:\users\admin\desktop\projekt\main.cpp:4 candidates are: osoba::osoba(const osoba&)       note c:\users\admin\desktop\projekt\main.cpp:4                 osoba::osoba(const std::string&, const std::string&, const std::string&)

pracownik need construct base class calling osoba's constructor, this:

pracownik::pracownik(const std::string & im,  const std::string & na, const std::string & pe, int liczba_godzin) : osoba(im, na, pe) , liczba_godzin(liczba_godzin) {}

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
