in saving.cpp in function deposit

void Saving::deposit(double d)
{
if (balance+d > 25.0)
{
setStatus(true);
cout <<"\nthanks your deposit will make your account active."<<endl;
}
else
{
setStatus(false);
cout <<"\nSorry your depositing will not make the account active."<<endl;

}
Account::deposit(d);
}

cannot do (balance + d)
i think it cannot read balance but i dont knoe why because class saving is inharited to the base class
