Hello everyone!
I have an assignment to create database using C++, plus some basic queries could be executed from that program . But I have no idea what to do and from where to start. so if anyone can guide me ,that what kind of data structure i should use and how, i will be very thankful.
This depends on what you mean by "database", a database can be as simple a flat file, or a multi-user, client-server type of system. You might want to start by determining your data storage/retrieval requirements, the amount and type of data to be stored and retrieved.
Once you have determined some of the basic requirements you can decide how to implement your database.

For anything beyond your beginner examples, I would recommend SQLite. There is also a SQLite++ wrapper for C++. There are some good examples there to get you started on that, if you need it.
But this is somewhat advanced.
You should consider using basic file I/O first.
