Develop an object oriented program in C++ to create a database of student information
system containing the following information: Name, Roll number, Class, division, Date of
Birth, Blood group, Contact address, telephone number, driving license no. etc Construct the
database with suitable member functions for initializing and destroying the data viz
constructor, default constructor, Copy constructor, destructor, static member functions, friend
class, this pointer, inline code and dynamic memory allocation operators-new and delete.
