*1 - Customer Initialization

  1.We are going to write a software to perform an online shopping application called Z-Kart.
  2.The back bone for every online retail application is its customers. The initial customer details for our system will be given in a file zusers_db.txt
  3.The file contains multiple lines and every line will be of the form
  
  UserName/Email EncryptedPwd Name Mobile

  [e-mail] ApipNbjm Rahul 9922992299

  2.The inventory of Z-Kart is initialized from the file z-kart_db.txt which is of below format
  
  Category Brand Model Price Stock

 Mobile Motorola G 12000 5
 Laptop HP Elite 56000 20
 Tablet Google ChromeBook 8000 12

*3 - 3 - New Account Signups

 1.There must be provision to sign up new accounts. While adding new customers, get their e-mail id, name, mobile number and password as input.
   Ask the user to re-type password to avoid any typos. Ensure that the password and re-typed password match.
 2.Since every customer needs to be identified uniquely, ensure that the given e-mail id is not existing in our registered Z-Kart database.
   If so, prompt the user to sign in instead of sign up
 3.Append the newly added customer details into the zusers_db.txt

*4 - Encryption

 1.It's generally not advised to store passwords directly in files. So the passwords present in the file are obtained by applying a simple encryption technique to    each and every individual character in the plain password.
 2.The encryption rule is very simple - add +1 to original char to encrypt it
   a will be encrypted as b
   m as n, z as a ( wrap around ) ...
   1 as 2, 9 as 0, 0 as 1....
   A as B, C as D, Z as A.....



Please take care of encrypting the password while writing to external storage
