[7], Some developers of C--, including Simon Peyton Jones, Joo Dias, and Norman Ramsey, work or have worked on GHC, whose development has led to extensions in the C-- language, forming the Cmm dialect which uses the C preprocessor for ergonomics.[4]. Declarations and types. Before the advent of ANSI C, the first edition of the text served as the de facto standard of the language for writers of C compilers. For quick viewing, C-SPAN provides Points of Interest markers for some events. C-- is a tightly-defined simpler alternative to C which supports all of these. Examples generally consist of complete programs of the type one is likely to encounter in daily use of the language, with an emphasis on system programming.
