Collection of C++ Helpers

C++ helpers developed incrementally to solve concrete needs/puzzles.

HTTP Scraper: C++ Class: it scrapes the time from www.timeanddate.com (the provided hyperling was not working).
File Reader: C++ Class: it takes in input the file stored in data/, then it tokenizes and provides methods list in normal and reverse order the tokens.
N-dimensional Dot Product: C++ Class: it takes in input 2 n-dimensional array and calculates parallely (using POSIX Threads) the Dot Product.

How to Start the Test Programs

From the root directory:

Http Scraper

	$ bin/bin/test_http_scraper 
	[main] scraping UTC time
	[main] provider www.timeanddate.com
	[main] scraped { dimanche 13 avril 2014, 18 h 01 m 14 }

File Reader

	$ bin/test_file_reader 
	[main] file read outcome [1]
	[FileReader][printContent] content <This is a simple test. I am doing my best, of course! Author: Paolo Maresca <plo.maresca@gmail.com> >
	[FileReader][reverseListTokens] token <<plomaresca@gmailcom>>
	[FileReader][reverseListTokens] token <Maresca>
	[FileReader][reverseListTokens] token <Paolo>
	[FileReader][reverseListTokens] token <Author>
	[FileReader][reverseListTokens] token <course>
	[FileReader][reverseListTokens] token <of>
	[FileReader][reverseListTokens] token <best>
	[FileReader][reverseListTokens] token <my>
	[FileReader][reverseListTokens] token <doing>
	[FileReader][reverseListTokens] token <am>
	[FileReader][reverseListTokens] token <I>
	[FileReader][reverseListTokens] token <test>
	[FileReader][reverseListTokens] token <simple>
	[FileReader][reverseListTokens] token <a>
	[FileReader][reverseListTokens] token <is>
	[FileReader][reverseListTokens] token <This>

N-dimensional Dot Product

	$ bin/test_nd_product 
	[main] vector A (4, 2, 7, 5, 1, 3, 6, 2, 8, 9)
	[main] vector B (3, 5, 2, 1, 7, 6, 9, 2, 1, 3)
	[main] sum dot product [159]

How to compile the source code

From the root directory, making use of the Makefile:

Clean previous build

	$ make clean

Creates a new build

	$ make

Compatibility

The build process has been tested only on Linux Fedora:

Uname

Limitations/Improvements

Some improvements might be done, in the source code some TODO have been left for future reworks.
