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).

The OP is undoubtedly talking about runtime iterators, since he referenced the iterator library. -- Dave Abrahams Boost Consulting www.boost-consulting.com
