If I have this:
for (auto iSong = 1; iSong <= iMaxSongNumber; iSong++)
Can I use the new for range approach?
I understand that for containers they need a begin and end method for them to work. But if we have literal max values?
There isn't a built-in mechanism to do this: range-based for works on something for which begin and end can be called.
I wrote a blog post about how to do this: https://www.justsoftwaresolutions.co.uk/cplusplus/generating_sequences.html
Basically, you need to create a "virtual container" with iterators that update the count.
