Sometimes I need the 5th element of something, regardless of what it is. Sometimes the 5th element of something needs to be compared to the 35th element of something else. Both cases require the use of direct and/or derived indexing. This is often the case in low-level code. As for why signed is default, this may have to do with the error handling in C. By convention, if a called function hits a failure mode, it returns a negative integer. If a function succeeds but with a caveat or warning, it returns a positive integer. Unqualified success returns zero. Hence why idiomatic C functions typically return int, not unsigned int, and we've been stuck on this convention ever since. |
