HTML Number to Text

html_to_text.cpp

/***********************************************************************************
 Basically takes a file with HTML numbers as input and outputs the converted text to another file.
HTML Numbers is:
A A
B A
etc.

Mainly did this to decrypt(?) lyrics from lyrics sites like SongLyrics.com which allow only viewing but not copying of lyrics (The whole GraceNote license thing) eg. http://www.songlyrics.com/flobots/we-are-winning-lyrics/ ... source code of the page shows the lyrics in HTML numbers.

Compiled with Codeblocks v. 8.02

To run, use "executable name i/p-file o/p-file" i.e command line arguments
