for example A,B,C,D are class all the 4 class contain one
method who() but the method who() implementaion is differnet
among each class. the relation among the 4 class are
A is base class and is inherited by B and C.and from this
two B and C where D is inherited.
the question is i want to display the output who() method in
all the classes(A,B,C,D)the output of who() method is
diferrent amond all the class(A,B,C,D)
------A------ virtuval who(print a)
override | |
who(print b) B C override who(print c)
| |
-------D------ override who(print d)

Answer / ana
only pure virtual function cant be executed, so A.who() can
be executed
and since you override who() in B, C and D, the output is
different

Answer / ap
First of the simple cases:
As you mentioned that function "who" in class is virtual and
hence the function from A cannot be executed. I am not sure
but if you try to execute A.who(), it will result in
run-time error.
and if you simply call obj_D.who() you will end up executing
the code defined in who() of class D.
now the slightly tricky one:
In case you want to execute function who() of Class B or C
from an object of type class D then you will have to
typecast the object as Class B or Class C.
I hope this helps.
