Limitations:
All the requirements given in the question have been completed by our team as best as possible. Some of the limitations are:
1.The Edit function does not allow flexible editing by the user. It requires specification of word and line number from which the word has to be deleted.
  New text can be added only to the end of the document. Text cannot be added in the middle of the document. New text added is always considered a new line and
  not continuation of previous line.
2. File name should not have spaces in between.
