Committee, commenced work on rigorously defining both the C language and the commonly provided standard C library routines. The results of their lengthymeetings are termed the ANSI-X3J11 standard, or informally as ANSI-C. The formal definition of ANSI-C introduces surprisingly fewmodifications to the oldK&R C language and only a fewadditions.
