K and R solutions to Revise the the main routine of the longest-line program so it will correctly print the length of arbitrarily long input lines, and as much as possible of the text. K and R C Programs Exercises provides the solution to all the exercises in the C Programming Language, second addition, by Brian W.Keringhan and Dennis M.Ritchie(Prentice Hall,1988).
