(a) Write a

(b) Using the class
that you created for Part (a), write the implementation of the default constructor,
initialising itsRadius with the value 5. |

(d) Consider the
following fragment of code: |

int SimpleCircle : : GetRadius() |
|
|
|
|
{ |
|
|
|
|
return *itsRadius; |
|

} |
|
|
and assume that Circle is an
object of SimpleCircle, that is |
|
|
|
SimpleCircle Circle; |
|
|
Write an instruction
that displays the radius for Circle on screen. |
