I have been checking out The C Programming Language by K&R (The book mostly everyone learned C from) and I was wondering why is it so popular among many programmers? A lot of beginners learned from the book but I find the book a little hard to follow. Why is K&R's book style so popular and loved by many programmers? Is it something really special or what? I noticed another book (Programming In Lua) is also said to be "K&R" style and again, it's popular and 5 stars by many on amazon. Can someone explain to me why "K&R" book style is so popular? It seems hard to follow to me.
