Write a program to maintain student’s record. Record should not be available to any unauthorized user. There are three (3) categories of users. Each user has its own type. It depends upon user’s type that which kind of operations user can perform. Their types and options are mentioned below: 1. Admin (Search Record [by Reg. No or Name], View All Records, Insert New Record, Modify Existing Record) 2. Super Admin (Search Record [by Reg. No or Name], View All Records, Insert New Record, Modify Existing Record, Delete Single Record) 3. Guest (Search Record [by Reg. No or Name], View All Records) When first time program runs, it asks to create accounts. Each user type has only 1 account (which means that there can be maximum 3 accounts). In account creation, following options are required: Login Name: <6-10 alphabets long, should be unique> Password: <6-10 alphabets long, should not display characters when user type> Confirm Password: Account Type: Login Name, Password and Account Type should be stored in a separate file in encrypted form.

When Program is launched with already created accounts, it will ask for user name and password to authenticate. On successful authentication, give options according to the user’s type.
