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.

What are oops functions?
This program numbers the lines found in a text file. Write a program that reads text from a file and outputs each line preceded by a line number. Print the line number right-adjusted in a field of 3 spaces. Follow the line number with a colon, then one space, then the text of the line. You should get a character at a time and write code to ignore leading blanks on each line. You may assume that the lines are short enough to fit within a line on the screen. Otherwise, allow default printer or screen output behavior if the line is too long (i.e., wrap or truncate). A somewhat harder version determines the number of spaces needed in the field for the line numbers by counting lines before processing the lines of the file. This version of the program should insert a new line after the last complete word that will fit within a 72-character line.
