Thread: problem with polymorphism

Hi guys, I had created a base class and its derived class, and Both the base class have a virtual function, say hi(). The base class is pretty much pure. Now I declared a pointer of the the base class, and created a derived class object with the pointer. I tried to call hi(), but Visual C++ gave me some funny errors:


d:\cryptography\crypter\crypter\crypter.cpp(149) : error C2248: 'BaseClass::Hi' : cannot access private member declared in class 'BaseClass'
d:\cryptography\crypter\crypter\crypter.h(45) : see declaration of 'BaseClass::Hi'
d:\cryptography\crypter\crypter\crypter.h(41) : see declaration of 'BaseClass

can someone please help me?'

OMG thankyou! I was so dumb. Anyway, I get a new error: d:\cryptography\crypter\crypter\power.h(8) : error C2143: syntax error : missing ';' before 'using'

and this is the bit where it points to.

Code:

#ifndef POWER_H
#define POWER_H

#include <iostream>
#include <string>
#include "Crypter.h"

using std::cout;    // here it is
using std::cin;
using std::endl;
using std::string;
typedef unsigned short int USINT;

thanks alot guys, i did forget a semi-colon after a class declaration
