Does this mean that forward declarations cannot be done on classes that might need to be inherited?

class CEmployee
{
public:
    virtual void CalcSalary( void ){}
 
protected:
    float m_HourlyRate;
    float m_HoursWorked;
};
 
class CAccountant : protected CEmployee
{
    public:
        void CalcSalary( void )
        {
            m_HourlyRate  = 50.0;
            m_HoursWorked = 1.0;
        };
};

Also, in the code above I was trying to use a forward declaration so that I could declare CEmployee after CAccountant, but the following compilation error was displayed:
error C2504: 'CEmployee' : base class undefined

Type in editor with [Alt + KeyPadNum] a number 155 and the same with [Alt + KeyPad] 0155, you will see they are two
different characters!?

char* nptr="0155";
 int total=0
int c=(int)(unsigned char)*nptr++;//c is 48 here
while (isdigit(c)) {//0,1,5,5 will return true here.
    total = 10 * total + (c - '0');
