Here you go: ***********
Not piracy I don't think. Ritchie long gone...
Search for K&R on the internet. I'm sure you will find a copy.

Plenty of classic and modern books in electronic format (usually EPUB nowadays, but I reckon PDF copies are still available) are scattered around the internet, usually broken up into pieces and shared amongst peers. Little bits of knowledge here and there. All you have to do is collect all those bits of knowledge and you'll end up with a full book. I advise keeping the pirate at bay.
