Learning C - Petewg/harbour-core GitHub Wiki

[being a Harbour programmer, the next stop (and a great favour you might want do to yourself) is to learn C language, if not already have done that. In fact, there are good reasons why you have to do it.] [*]

  • Remark: Under MinGW gcc, in order to enable/utilize "new" C99 length modifiers like f.e. hh ll z, must the _ISOC99_SOURCE feature test macro been defined, since it's not defined by default; this can be done either by adding a line #define _ISOC99_SOURCE on top of source code (preferably before any #include <headerfile>) or by using -D_ISOC99_SOURCE command line switch. e.g.: gcc src.c [-options...] -D_ISOC99_SOURCE

_{[«... intuitively speaking, C might be regarded as being for the programming languages, exactly what the ancient Greek is for most western human languages: constantly influencing, while vigorously concise and rigorously severe; a diachronic, almost atavistic point of reference, each one in their own area.
C is the constitutional "back panel" in the software evolution, indeed » (~08/2017)]}
