Thread: Help figuring out error

I keep getting this error when I compile:

Code:

In function 'std::ostream& operator<<(std::ostream&, User&)':
error: no match for 'operator<<' in 'os << u->User::userID'
note: candidates are: std::ostream& operator<<(std::ostream&, User&)

And here's the operator

Code:

friend std::ostream& operator<<( std::ostream& os, User& u ){
		os << u.userID << " " << u.name << " " << u.systemKey << " " << u.accessKey;
		return os;
	}

I'm not even calling the "<<" operator anywhere in my code. My code only creates three users, that's it. I can't get past compile.

Any help is most appreciated!

????

Here's my code so far.

users.h

Code:

#ifndef USERS_H_
#define USERS_H_

#include <string>

typedef unsigned char uchar;
typedef unsigned int uint;

class User{
	
	public:
		User( uint id, std::string name );
		virtual ~User(){};
		const uchar& checkSystemKey() const;
		const uchar& checkAccessKey() const;
		void setSystemKey( uchar& system );
		void setAccessKey( uchar& access );
		
	friend std::ostream& operator<<( std::ostream& os, User& u ){
		os << u.userID << " " << u.name << " " << u.systemKey << " " << u.accessKey;
		return os;
	}

	protected:
		User( const User& );
		User& operator=( const User& );
		uint userID;
		std::string name;
		uchar systemKey;
		uchar accessKey;
};

class SysAdmin : public User{

	public:
		SysAdmin( uint id, std::string name, uchar system );
		virtual ~SysAdmin(){};
		void addSystemUser( User& user );
		void setUserAccess( User& user, uchar& access );
		
	private:
		uchar mySystemKey;
};

class SiteAdmin : public SysAdmin{

	public:
		SiteAdmin( uint id, std::string name, uchar system );
		User* createBasicUser( uint id, std::string name );
		User* createSysAdmin( uint id, std::string name, uchar system );
};

#endif

users.cpp

Code:

#include "users.h"

User::User( uint id, std::string name )
: userID( id ), name( name ), systemKey( 0x00 ), accessKey( 0x00 ) {}

inline const uchar& User::checkSystemKey() const{
	return systemKey;
}

inline const uchar& User::checkAccessKey() const{
	return accessKey;
}

inline void User::setSystemKey( uchar& system ){
	systemKey = systemKey | system;
}

inline void User::setAccessKey( uchar& access ){
	accessKey = accessKey | access;
}

SysAdmin::SysAdmin( uint id, std::string name, uchar system )
: User( id, name ), mySystemKey( system ) {}

inline void SysAdmin::addSystemUser( User& user ){
	user.setSystemKey( mySystemKey );
}

inline void SysAdmin::setUserAccess( User& user, uchar& access ){
	user.setAccessKey( access );
}

SiteAdmin::SiteAdmin( uint id, std::string name, uchar system )
: SysAdmin( id, name, system ) {}

User* SiteAdmin::createBasicUser( uint id, std::string name ){
	return new User( id, name );
}

User* SiteAdmin::createSysAdmin( uint id, std::string name, uchar system ){
	return new SysAdmin( id, name, system );
}

main.cpp

Code:

#include <iostream>
#include <string>

#include "users.h"

int main(){

	SiteAdmin Chris( 1, "Chris", 0x80 );
	User* Eric = Chris.createBasicUser( 2, "Eric" );
	User* Mike = Chris.createSysAdmin( 3, "Mike", 0x40 );
	
	return 0;
}

ah, that worked.
