вот есть заголовочный файл с классами

в маине обращаюсь так

#include "Reservoirs.h"
#include <stdio.h>
#include <conio.h>

void main()
{
	BaseReservoir a( "O\0" , 123 );
	a.Scan( a );
	a.Print( a );
		
	NaturalReservoir b( 40 );
	b.Print( b );

	ArtificialReservoir c( "12.12.2012" );
	c.Print( c );

	_getch();
}

Но чего-то ошибок много вообще не пойму
