Answer 1

I think the static analyzer is not seeing how _numberOfColumns can become non-zero, and hence its insistence that garbage is being assigned. You need to check that you are actually providing some means for _numberOfColumns to become non-zero.

Generally when I am writing loops that want to find the largest or the smallest value, I initialize the size variable to the largest (if I want the smallest) or smallest (if I want the largest) amount, and I think this will solve most of your issues:

float shortestHeight = FLT_MAX;
for (unsigned i = 0; i < _numberOfColumns; i++)
{
    // etc.
}
