It's a perfectly > legit standard function. Yes, I understand that. However, most of <cstdio> has equivalent functionality within <iostream>, and I want to properly understand what the <iostream> way of doing such things is. In particular, I was curious whether either of the two ways of doing this was noticeably superior to the other. What I've learned is that they're pretty similar for this kind of task. The code I'm working on right now is not code that I'm entirely free to change as I desire - there's a couple of different versions of the program, and when I make my fix to our version, the people responsible for the other versions will find it easier to incorporate my fix if it doesn't require them to switch from <iostream> to <cstdio>. I'd guess that if I did deliver <cstdio>-based code, they'd assume that I was a C programmer doing so due to my ignorance of <iostream> (which is mostly - but not entirely - wrong). |

Circular is slightly more tricky. Currently the IterPair class is holding 2 iterators which are just incremented in operator++. One could also store the container begin() and end() in the IterPair class and if it2_ reaches the end, wrap it over to begin. Cheers Paavo |
