Klassen

Beispiel Klasse Complex

class Complex
{
public:
    double _real;
    double _imag;
public:
    Complex(): _real(0), _imag(0) {}
    Complex(double real, double imag):  _real(real), _imag(imag) {}
    Complex(const Complex &src):  _real(src._real), _imag(src._imag) {}
    Complex& operator =(const Complex& source){
        _real = source._real;
        _imag = source._imag;
        return *this;
    }
};
class Vector : public Complex {
  Vector(): Complex() {}
  ~Vector() {}
  Vector(const Vector &src): Vector(src): Complex(src) {}
  Vector& operator =(const Vector& src): { Complex::operator =(src); return *this; }
}

Beispiel Interface

class Box {
   public:
      // pure virtual function
      virtual double getVolume() = 0;
};

public:
  ReException(const char* message);
  ReException(const char* message, const char* file, int line);
  virtual ~ReException();
public:
  ReException(const ReException& source): _message(source._message){};
  ReException& operator =(const ReException& source){ _message = source._message; }
protected:
  ReException();
public:
  inline void setMessage(const char* message) {
    if (m_message != NULL)
      free((void *) m_message);
      m_message = _strdup(message);
    }
  }
  inline const char* getMessage() const {
    return m_message;
  }
protected:
  const char* m_message;
};
