Boost Range Library: Traversing Two Ranges Sequentially

Question

Boost range library (http://www.boost.org/doc/libs/1_35_0/libs/range/index.html) allows us to abstract a pair of iterators into a range. Now I want to combine two ranges int

Answer 1

• Can't you call the function twice, once for both ranges? Or are there problems with this approach?
• Copy the two ranges into one container and pass that.
• Write your own range class, so it iterates through r1 first and and through r2 second.
