C++ Iterator Question

by **Andy** » Apr 20, 2006 @ 4:54pm

I'm looking for an iterator adapter that will allow me to glue together two (or more) disjoint iterator ranges. Something like this:

Code: Select all

1 
2 
3 
4 
5 
6 
7 
8 
9 
10 
11 
int a1[] = { 1, 3, 5 };
int a2[] = { 2, 4, 6 };

disjoint_iterator it<int>(a1, a1 + 3,
                          a2, a2 + 3);

sort(it, it + 6);

// results:
// a1 == { 1, 2, 3 }
// a2 == { 4, 5, 6 }
11 lines; 3 keywds; 9 nums; 31 ops; 0 strs; 3 coms    Syntactic Coloring v0.4 - Dan East

Is there such a thing?

Nothing like that built into the language or standard library.

You will have to right your own. Shouldn't be too hard.
