Project Name : ChatBot

Developers : AKHIL VARMA & VINAY

Description :
    A simple chatbot which reads the text files provided to it and gives answers accordingly.
If it does not answer the question u have asked than u can feed any answer for your question.
The answer u have feeded will be stored in the file automatically for later use.

Problems :
    -> It can not answer any question which is not present in the file which is fed into it.  
    -> It would give u an error if u will write the last line of the file as question.

Use your own files :
    U can use your own files but following things should be done carefully :
    -> The file should have ".txt" extension.
    -> Question should be entered on one line without any spaces.
    -> Answer should be on the very next line of the question. Write the answer in the way u want to display it.
