Question

I try to make class where I can creat new object of Student.
I’ve got some problem with definition of class body (student.cpp) and class (student.h).

Error:

In file included from student.cpp:1:
student.h:21:7: warning: no newline at end of file
student.cpp:6: error: prototype for `Student::Student()' does not match any in class `Student'
student.h:6: error: candidates are: Student::Student(const Student&)
student.h:8: error:                 Student::Student(char*, char*, char*, char*, int, int, bool)

student.cpp

 //body definition  
    #include "student.h"
    #include <iostream>

    Student::Student()
    {
    m_imie = "0";
    m_nazwisko = "0";
    m_pesel = "0";
    m_indeks = "0";
    m_wiek = 0;
    m_semestr = 0;
    m_plec = false;

}

student.h

//class definition without body

#include <string.h>

class Student {
    //konstruktor domyslny
    Student (char* imie, char* nazwisko, char* pesel, char* indeks, int wiek, int semestr, bool plec): 
    m_imie(imie), m_nazwisko(nazwisko), m_pesel(pesel), m_indeks(indeks), m_wiek(wiek), m_semestr(semestr), m_plec(plec)
    {}  
        private:
        char* m_imie;
        char* m_nazwisko;
        char* m_pesel;
        char* m_indeks;
        int m_wiek;
        int m_semestr;
        bool m_plec;
};

Answer 1

You wrote a body for a Student constructor that doesn’t take any parameters:

Student::Student( /* NO PARAMETERS */ )

But this function, Student(), is not in the class-definition.
This generates the error:

 prototype for `Student::Student()' does not match any in class `Student'

You need to write:

class Student {
    public:
        Student();  /* NOW it is declared as well as defined */
    [... all the other stuff ...]
}; 

Now, there is both a prototype for Student() and also for Student(/* 7 parameters */)

The fix for the other error is simple:

student.h:21:7: warning: no newline at end of file 

The fix is to put a newline at the end of the file! 🙂
