A client is supplied with the following declaration for a base class and a derived class: class BaseClass { public: void PrintFields () const; }: class DerivedClass: BaseClass { public: void NewFunction (); DerivedClass(int StartValue); }; The client writes the following code to call the constructor for an object of type DerivedClass, and then prints the fields in the newly created object. DerivedClass anObject (10); anobject.PrintFields (): The compiler reports an error for the second statement. What's wrong? How would you fix this problem?
