Message: [QUOTE="Alf P. Steinbach, post: 2829851"] * arnuld:[i] This looks good. I'd add an extra 'const', "const char* const arr[]", but that's it. Some people may comment on the use of 'unsigned' for the loop variable, because 'unsigned' can become problematic for a loop that counts down; however, with e.g. std::vector there are good reasons to use std::size_t for the loop variable, and that's an unsigned type too. This also looks mainly good. Improvement: in order to get warnings about some (real nasty) problems you need to add the "-O" (optimize) option, or some other optimization. The only further problem is that I seem to remember that the g++ folks have deprecated -Wall, and introduced some other option or set of options. However, I use -Wall myself. But then, I also use "-o" (out file) with Visual C++, which is an undocumented option. So perhaps I'm not the best example to follow.[/i] [/QUOTE]
