3. Develop an object oriented program in C++ to create a database of the personnel information system containing the following information: Name, Date of Birth, Blood group, Height, Weight, Insurance Policy, number, 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.
