vs
auto it = hashmap.begin();
I find auto useful for cutting down some of the verbosity of templates STL containers, but I can see how over use can lead to code requiring much more referencing if maintaining code that rarely defines types.
- therein 11y agoOh no, I agree with that. I was specifically talking about fenesiistvan's point about his STL wrapper. I was wondering what his use cases were. No doubt auto is extremely useful in a case like the one you mentioned. In fact, even more so in here: for (std::unordered_map<std::string, std::unordered_map<std::string, long>*>::const_iterator it = a.begin(); ...)
- fenesiistvan 11y agoI am used with the old Delphi / C++ Builder style. I think that it is much more clear than than bot the STL and the new trendy C11 style. So my hashmap handling looks like this: MHashMap userlist = new MHashMap<HUser>(); HUser *user = userlist->First(); while(user) { user->DoSomething(); user = userlist->Next(); }
