(i) Out of the following, which of the options is correct for calling function 2?
Option 1 - Race T(30);
Option 2 - Race U(R);.
(ii) Name the feature of object oriented programming, which is illustrated by function1, function2
and function 3 combined together.
(c) Declare a class myfolder with the following specification: [4]
Private members of the class

l Availspace – long ( to represent total number of bytes available in myfolder)
l Usedspace – long ( to represent total number of bytes used in myfolder)
Public members of the class
l Newfileentry() – A function to accept values of Filenames, Availspace and Usedspacefromuser
l Retavailspace() – A Fucntion that returns the value of total Kilobytes available (1 Kilobytes =
1024 bytes)
l Showfiles() – a function that displays the names of all the files in myfolder
