question 8

Multiple Choice

Consider the following class definitions:
class bClass
{
Public:
Void set(double a,double b) ;
//Postcondition: x = a; y = b;
Void print() const;
BClass() ;
//Postcondition: x = 0; y = 0;
BClass(double a,double b) ;
//Postcondition: x = a; y = b;
Private:
Double x;
Double y;
};
Class dClass: public bClass
{
Public:
Void set(double a,double b,double c) ;
//Postcondition: x = a; y = b; z = c;
Void print() const;
DClass() ;
//Postcondition: x = 0; y = 0; z = 0 ;
DClass(double a,double b,double c) ;
//Postcondition: x = a; y = b; z = c;
Private:
Double z;
};
