Hello!
What is the difference between "library parts" of C99 and "language
parts" of C99.
The language includes the libraries; perhaps you mean the syntax as
opposed to the libraries. Basically, anything supplied as a function or
macro will be found declared in a header and any supporting functions
will be found in a library.

Plauger uses the terms "library bits" and "language bits", not "library
parts" and "language parts." He is writing informally; none of those
four terms has any defined meaning in C, although most users of C will
recognize that he is distinguishing between those parts of the language
specified in section 7 "Library" of the language standard from the
non-library parts defined in sections 1-6. The annexes A-J contain
supplemental information concerning all 7 sections of the language
specification.

I know that "Dinkum Compleat Libraries" (http://www.dinkumware.com/)
support the "library parts" of C99 - this probably relates to the C99
library headers and the functionality they provide.?
The headers and library functions defined by the C language
specification are what Dinkum supplies.
Are the "language parts" of C99 perhaps things like "variable
declarations" in the middle of {}-blocks? See below...
No doubt Plauger means by "language bits" everything not specified as
belonging in a library or associated header. Obviously, variables and
their declarations (no matter where they occur) are part of that.

}
What else might be included in the "language parts" of C99?
In your code, <stdio.hand printf() are defined as part of the library
in the language specification. Everything else is a non-library part of
the C programming language.
