Pimp My Code Part 1 Redux

Not exactly a redux, but very similar to last time:

bIsNotEmpty = false;
if (vNests.GetSize() != 0) {
  if (vNests[0]->vEggs.GetSize() != 0) bIsNotEmpty = true;
}

First of all we don’t actually care about the size, we just care that we have (Or don’t have) a nest with eggs in it. Depending on the container GetSize may or may not be a variable look up. IsEmpty is always a variable lookup:

bIsNotEmpty = false;
if (!vNests.IsEmpty()) {
  if (!vNests[0]->vEggs.IsEmpty()) bIsNotEmpty = true;
}

We can combine this into a single line:

bIsNotEmpty = (!vNests.IsEmpty() && !vNests[0]->vEggs.IsEmpty());

I would use more descriptive variable naming change my logic to use bIsEmpty/!bIsEmpty. Using bIsNot variables is often confusing and leads to harder to read code:

bIsNestWithEggs = (!vNests.IsEmpty() && !vNests[0]->vEggs.IsEmpty());
bIsEmpty = !bIsNestWithEggs;
// Use bIsEmpty and !bIsEmpty from now on
