Re: Dynamic foreach algorithm

Responding to Daniel T...

foreach(level1 = 0; level1 < somecount; level++) {
foreach(level2 = 0; level2 < somecount2; level2++) {
// do something with level1 and level2
}
}

If you knew in advance that you three such levels you would do this

foreach(level1 = 0; level1 < somecount; level++) {
foreach(level2 = 0; level2 < somecount2; level2++) {
foreach(level3 = 0; level3 < somecount3; level3++) {
// do something using level1, level2, level3
}
}
}
First note that the bodies of these two examples are necessarily different because they are parameterized differently (i.e., the second example needs level3 but the first does not).

We really don't know that for sure. The bodies of the loops in the two examples may very well not *need* the extra variable. That's why I asked early on what they looked like.

I was taking his code comments at face value.
