/*Assignment 2
Chaitanya Nitin Pawar
SE_B_48
Problem statement: Develop a program in c++ to create a database of student's information system containing the following information: Name, Roll no, 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 function, friend class, this pointer, inline code and dynamic memory allocation operator new and delete as well as  exception handling
