Question $1$:

Consider the following class definition:

class circle

$\{$

public

void print$()$ const;

void setRadius $($double$)$;

vold setCenter$($double$,$ double$)$;

vold getCenter$($double&$,$ double&$)$;

double getRadius$()$;

double area$()$;

circle$()$;

circle$($double$,$ double, double$)$;

private:

double xCoordinate;

double yCoordinate;

$\}$;

double radius;

$\}$;

class cylinder: public circle

$\{$

public

void print$()$ const;

vold setHelght $($double$)$;

double getHelght$()$;

double volume$()$;

double area $()$;

cylinder $()$;

cylinder $($double$,$ double,

double, double$)$;

private:

double helght;

a$.$ Suppose that you have the declaration:

cylinder newCylinder;

List the private members of the object newCylinder.
