Creating anonymous functions?

eighty · 2003-07-09T20:09:03

Is it possible to create functions without names, just like you can create objects without names? So that you can have an array of functions without real names that clutter up the global (or any) namespace. void func() { /*blah*/ } // instead I want something like: void (*pFunc)() = ???

Check out Boost Lambda (http://www.boost.org). It's fairly limited and not nearly as flexible as lambda constructs in (mostly) functional languages, but if your needs are simple, it might be what you're after.

Interesting... I'll check it out.

Gcc does, but not g++, AFAIK. It only works as an extension to the C language.

Hm... I was under the impression gcc == g++...?

Thanks for the replies.

Most (all?) extensions are language specific. AFAIK, all the languages supported by GCC are compiled to a Lisp-like intermediate code by the language specific frontend. The resulting code is then compiled by the compiler backend. Therefore, the C++ frontend will likely not be able to handle a C extension, and vice-versa.

I could be wrong of course: I don''t know GCC''s internals, so feel free to correct me.

Hope this helps.

Umm... I meant I thought gcc was the same thing as g++. Just another name for it. I guess I was wrong.

gcc used to stand for GNU C Compiler. Now, it stands for GNU Compiler Collection, and includes the C compiler (gcc), the C++ compiler (g++), the pascal compiler, as well as a couple others (I forget exactly which ones).

C, C++, Object C, Fortran, Java, and Ada are supported by gnu, and there are many other front-ends available.

gcc will call the correct back end for the job. You need C++? It''ll send your code to g++. You need Fortran? g77 handles it. Etc.

As noted, the best solution may be to use another language. OCaml might be a good place to start (good reputation for speed, supports procedural, OO, and functional paradigms (with a focus on functional))
