This is the error I am getting:

C:\Dev-Cpp\book.cpp no `void bookinfo::newbook(bookinfo&, std::string, std::string, std::string, std::string, std::string, std::string)' member function declared in class `bookinfo'

book.cpp

#ifndef __book_h__
#define __book_h__
#include <string>
using namespace std;

class bookinfo
{
  public:
  void newbook(bookinfo & book, string number, string lastname,
               string firstname, string title, string genre,
               string availability);
  string getlastname();
  string getfirstname();
  string getcatnumber();
  string getbooktitle();
  string getgenre();
  string getavailability();
  
  private:
  string catalognumber;
  string authorlname;
  string authorfname;
  string booktitle;
  string genre;
  string availability;
};

#endif

book.cpp

#include "book.h"


 void bookinfo::newbook(bookinfo & book, string number, string lastname,
             string firstname, string title, string genre,
             string availability)
{
  book.catalognumber = number;
  book.authorfname = lastname;
  book.authorlname = firstname;
  book.booktitle = title;
  book.genre = genre;
  book.availability = availability;
}

Compiles fine here on g++ 4.7.2. So either your compiler is acting up (DevC++ is an old IDE, and by default uses preinstalled oooold version of MinGW), or there's some other issue.


Also, don't put using namespace std; in global scope in header files. Just don't - it can end up with hard to debug, name-resolving related, (at worst case) "science fiction" bugs.

What compiler would you recommend?

It depends on the OS (Operating System) you're running. GCC (GNU Compiler Collection) is probably the most widely used compiler. You can use it on Windows, but most people running Windows use Microsoft Visual Studio because it's not just a compiler, but a full-fledged IDE (Integrate Development Environment). You don't need an IDE but it definitely helps when you're a beginner.
