    Help w/inheritance and virtual funcs PLEASE!!!

    Hello,

    OK, Here's my problem. I have created a base class CBaseAnimal that has a virtual function in it. Here's its def:

    class CBaseAnimal {
    public:
    virtual void speak() =0;
    };

    Now I derive a class CDog based on CBaseAnimal:

    class CDog : public CBaseAnimal {
    };

    NOW I define speak():
    void CDog::speak()
    {
    cout << "BARK BARK!";
    }

    When I compile (using VC++6), I get the error SetName' : member function not declared in 'CHumanPlayer''!! Shouldn't it be because I derived CDog FROM CBaseAnimal??? PLEASE HELP ME!!!!
    ------------------------------------------
    Normally I'd put something clever, but that isn't the point of being here now is it?

    A. We don't see where SetName is declared
    B. We don't see where SetName is used

    Post more relevant snippets if you want real help.

    Where is the code that uses the class CHumanPlayer?
    1 rule of the Samurai Code: if you have nothing to say, don't say anything at all!

    Where is the Humanity?
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }
