I'm not quite understanding the question but if your wondering how/where to get the book:
-> you could get it for about $9 at Textbooks.com:

-> I wouldn't recommend this but there might be a PDF version you could download with some serious searching.
-> have you already considered/found this?: http://cs.armstrong.edu/liang/intro6e/intro6estudentsolution.html
(There is a big 'Download' link under 'Programming Exercise Solutions' for that book)
