(2nd edition, 51st printing, August 2013)

• Solve problems efficiently in pure C.
• Write portable solutions so the code can be tested almost anywhere.
  • Write in ANSI C (C89).
  • Use POSIX makefiles, avoiding GNU Make extensions that may not be available.
• Be pedantic; turn on essentially all warnings -Wunused-variable -Wno-implicit-int -Wno-return-type -pedantic -ansi -Werror
• Use good K&R style (for a given problem, use only techniques that have already been covered)
