Hi folks:
I quite often have to write code to do the following:
Given N sequences, generate all the N-tuples s.t. the i'th element in each tuple is drawn from the i'th sequence.
For example, if sequence S1 is { 1, 2, 3 } and sequence S2 is { 10, 20 }, I need to generate these tuples: (1, 10), (2, 10), (1, 20), (2, 20).
I think this problem could be solved elegantly with a iterator similar to zip_iterator. I have some questions:
Why not use zip_iterator?
(1) Is there already a way to do this in boost?
http://www.boost.org/libs/iterator/doc/zip_iterator.html ??
(2) If not, would this be a worthwhile addition to the iterator library?
Don't we already have it? -- Dave Abrahams Boost Consulting www.boost-consulting.com
