using namespace std; const double Pi = 3.141592654;

Question

What will be an ideal response?

Answer 1

```
class Vect {
public:
Vect() {} //Constructor 1 - components uninitialized
Vect( double, double ); //Constructor 2 - components initialized
Vect( const Vect& ); //Constructor 3 - initializing
double xcomponent( Vect ) const;//Member Function - x magnitude
double ycomponent( Vect ) const;//Member Function - y magnitude
private:
double r; //magnitude
double theta; //direction (radians)
friend istream& operator>> ( istream&, Vect& );
friend ostream& operator<< ( ostream&, const Vect& );
friend Vect operator+ ( const Vect&, const Vect& );
friend Vect& operator+= ( Vect&, const Vect& );
};
