Total Number of words in the list is _______

Alphabetical listing of words is:

------

Assume the end of the list is indicated by ZZZZZZ and there is maximum in 25 words in the Text file.

hello all, how are you all doing. my name is Siraj and this file is created just to make a program. anything is written in this
