c - What is meant by this cast? (int (*)[10]) -


i stumbled across following cast:

(int (*)[10])

in opinion, "pointer pointer int". let's assume following array declaration:

int array[10];

then assume &array of type (int (*)[10])

is correct?

in opinion, "pointer pointer int".

no. pointer array of 10 ints.

then assume &array of type (int (*)[10])

yes. assumption correct. &array address of array array , of type int (*)[10].

Using Java 8 lambdas/transformations to combine and flatten two Maps -

i have 2 maps: map<a, collection<b>> mapab map<b, collection<c>> mapbc i transform them map<a, collection<c>> mapac , i'm wondering if there's smooth way lambdas , transformations. in particular case, collections sets, i'd solve problem collections in general. one thought had first combine 2 maps map<a, map<b, collection<c>>> , flatten it, i'm open approach. data notes: b should occur in value collection associated 1 a , , same true mapbc (a given c mapped 1 b ). result, there should 1 path given a given c , although there may a -> b mappings there no b -> c mappings , there may b -> c mappings there no corresponding a -> b mappings. these orphans don't appear in resulting mapac . for sake of comparison, here's example of purely imperative approach same problem: map<a, collection<c>> mapac = new hashmap<>(); (entry<a, collection<b>> entry...
