hmm im trying to find the number of lines the the text document.

Using your while loop i can easily do it with size(TheCellArray) which I get

1 20

*So 20 lines

However, working with ShortStory.txt which is opened with
T= fopen('ShortStory.txt','rt')
when I use

T1 =size(T)


I get like

1 1


which doesn't make sense to me, the total lines of the cell array and txt should be the same....

Yes, that would be an appropriate way

Remember what I wrote earlier, that what is returned by fopen is just a
file identifier, which is a simple number such as 3 . The file
identifier has no meaning on its own, but it is used by the I/O routines
to as the indicator of _which_ file you want to work with, without
having to re-specify the file information for each operation.

Like when you drive your car into a mechanic, they record all kinds of
information about the owner, model, license plate, vehicle
identification number, odometer reading, and what-not -- but once that
is done, what the mechanic gets told is "the car in bay #3 needs its oil
changed". The bay number gets used as the reference identifier for which
vehicle needs to be operated on, but the size of the bay _number_ has
nothing to do with the size of the _vehicle_ or how many rows of seats
it has.
