Constructor troubles

Expand Post »

Hi out there.

I can't get the constructors in my header files to work.

Here's a copy of my header file code:

C++ Syntax (Toggle Plain Text)
#ifndef GUARD_PHEADER_H
#define GUARD_PHEADER_H
 
//The header file for the Person.cpp.
//person_header.h
 
#include <iostream>
#include <string>
 
//Person class declaration
class Person {
public:
       std::istream& read_surname(std::istream&);
       std::istream& read_name(std::istream&);
       std::istream& read_phone(std::istream&);
       std::istream& read_age(std::istream&);
       std::istream& read_weight(std::istream&);
       std::string& read_phone(std::string&);
       int& read_age(int&);
       double& read_weight(double&);
       std::string get_name() const { return name; }
       std::string get_surname() const { return surname; }
       std::string get_phone() const { return phone; }
       int get_age() const { return age; }
       double get_weight() const { return weight; }
       person(std::string&, std::string&, std::string&, int&, double&);
       Person(std::ifstream&);
private:
        std::string surname;
        std::string name;
        std::string phone;
        int age;
        double weight;
    };    
#endif
#ifndef GUARD_PHEADER_H
#define GUARD_PHEADER_H

//The header file for the Person.cpp.
//person_header.h

#include <iostream>
#include <string>

//Person class declaration
class Person {
public:
       std::istream& read_surname(std::istream&);
       std::istream& read_name(std::istream&);
       std::istream& read_phone(std::istream&);
       std::istream& read_age(std::istream&);
       std::istream& read_weight(std::istream&);
       std::string& read_phone(std::string&);
       int& read_age(int&);
       double& read_weight(double&);
       std::string get_name() const { return name; }
       std::string get_surname() const { return surname; }
       std::string get_phone() const { return phone; }
       int get_age() const { return age; }
       double get_weight() const { return weight; }
       person(std::string&, std::string&, std::string&, int&, double&);
       Person(std::ifstream&);
private:
        std::string surname;
        std::string name;
        std::string phone;
        int age;
        double weight;
    };    
#endif

And a copy of the function code:

C++ Syntax (Toggle Plain Text)
//Constructor for Person
 
Person::person(std::ifstream& in) : surname(0), name(0), phone(0), age(0), weight(0.0) { }
 
//Constructor for Person
Person::person(): surname(0), name(0), phone(0), age(0), weight(0.0) { }
//Constructor for Person

Person::person(std::ifstream& in) : surname(0), name(0), phone(0), age(0), weight(0.0) { }

//Constructor for Person
Person::person(): surname(0), name(0), phone(0), age(0), weight(0.0) { }

I keep getting all the weird errors that you can find in my compile log. I'm running Dev C++ on Windows XP.

Thanx:cheesy:

Re: Constructor troubles

Oh yeah, the error on line 26 occurs in the header and 68 and 71 occur in the definition of the functions

Re: Constructor troubles

Remeber that C++ is case-sensitive (uppercase and lowercase matter).
