Since its release, Arduino has become more than just a development platform; it has become a culture built around
the idea of open source and open hardware, and one that is reimagining computer science and education. Arduino has
opened hardware development by making the starting skills easy to obtain, but retaining the complexities of real-world
application. This combination makes Arduino a perfect environment for school students, seasoned developers, and
designers. This is the first Arduino book to hold the title of “Pro,” and demonstrates skills and concepts that are used by
developers in a more advanced setting. Going beyond projects, this book provides examples that demonstrate concepts
that can be easily integrated into many different projects and provide inspiration for future ones. The focus of this book
is as a transition from the intermediate to the professional.

This project attempts to implement a Database using B+Tree. The project has developed a DATABASE SYSTEM with lesser memory consumption. Its API includes simple SQL Statements and the output is displayed on the screen. Certain applications for which several features of existing databases like concurrency control, transaction management, security features are not enabled. B+Trees can be used as an index for factor access to the data. Help facility is provided to know the syntax of SQL Statements.
Implemented BFS, DFS and A*
To compile this project, use the following command:
g++ -o search main.cpp
Then you can run it:
./search
The input is loaded from a input file in.txt
Here is the format of the input file:
The first line of the input file shoud contain two chars indicate the source and destination city for breadth first and depth first algorithm.
The second line of input file shoud be an integer m indicate the number of connections for the map.
Following m lines describe the map, each line represents to one connection in this form: dist city1 city2, which means there is a connection between city1 and city2 with the distance dist.
The following input are for A*
The following line contains two chars indicate the source and destination city for A* algorithm.
Then there is an integer h indicate the number of heuristic.
The following h lines is in the form: city dist which means the straight-line distance from the city to B is dist.
