> No, it mostly affects execution time. Citation needed. Yes, the -1 appears in the source code. It might even appear in the intermediate representation. It'll even show up in the assembly for multidimensional arrays (but it'll all get folded into a single `mov` assembly for vectors). But I dare you to actually demonstrate a performance difference. Compared to a memory access, a `dec` is free.
