Assignment 2
Name : Swaraj Sachin Gosavi
Roll no : 21327
Batch : F3 [SE 3]

Develop a program in C++ to create a database of student’s information   system   containing   the   following   information: 
Name,  Roll  number,  Class,  Division,  Date  of  Birth,  Blood group, contact address, Telephone number, Driving license no. and   other.   
Construct   the   database   with   suitable   member functions.  
Make  use  of  constructor,  default  constructor,  copy constructor,  destructor,  static  member  functions,  friend  class, this   pointer,inline  code   and  dynamic   memory   allocation operators-new and delete as well as exception handling.
