$5.$The below program shows how constructor is used to give initial values to the instance variables defined by the class, or to perform any other startup procedures required to create a fully formed object. $/*$ Unit $3$ Lab Ex:$5$

Same as Ex:$4$ but will show how constructor is used to give initial values to the instance variables defined by the class, or to perform

any other start up procedures required to create a fully formed object.
