2. Wide casting

Demo on "Narrow Casting" Parent class->M1 , Child class-
>M1,M2
Attributes of super class can only be accessed.
Methods defined at Super class(M1) can only be accessed.
Methods with REDEFINED Logic(M1) will be called
Methods in child class (M2) cannot be accessed
Demo on "Wide Casting" Parent class->M1 , Child class->M1,M2
Assign address of PARENT to CHILD Class object
Methods defined at child class(M2) can also be accessed
with Parent reference.
Methods with REDEFINED Logic (M1) will be called
The cast is only possible if the object was instantiated as
the child and then it was casted to the parent object and
then back again to the child object. The child has
everything the parent has so there is no problem with this
path.
