ok i'm confused in vectors and iterators
my question is, i created two vectors
then created an iteratorCode:vector<string> inventory; vector<string> words;
so to which vector does the invIterator belong ? i haven't tried compiling this but will this compile ?Code:vector<string>::iterator invIterator;
If you have two vectors of the same type,, I do this:
It is always best to have an iterator to a vector, no matter if they are the same base type like above. If you name you iterators similar to the vector that it represents, you will not get confused when it comes to working with them.Code:std::vector<std::string> inven; std::vector<std::string> names; std::vector<std::string>::const_iterator invenIter; // works with inven string vector std::vector<std::string>::const_iterator namesIter; // works with names string vector
Double Helix STL
ok after coding like yours i can still use invenIter with the names vector right ?
i mean that im allowed to use it
If you wanted to, yes. Obviously it would be confusing and bad.Originally Posted by manzoor
If you called it
it would be assumed to be a more general purpose vector iterator.Code:vector<string>::iterator vectIterator;

I usually name my iterators it or iter...
It doesn't belong to anything until you assign an iterator to it.
i.e.
Code:vector<string>::iterator invIterator = inventory.begin();
thanks every one i now understand it :P
