vectors iterator

ok i'm confused in vectors and iterators

my question is, i created two vectors

Code:

---

vector<string> inventory;
vector<string> words;

---

then created an iterator

Code:

---

vector<string>::iterator invIterator;

---

so to which vector does the invIterator belong ? i haven't tried compiling this but will this compile ?

If you have two vectors of the same type,, I do this:

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

---

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.

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.

If you called it

Code:

---

vector<string>::iterator vectIterator;

---

it would be assumed to be a more general purpose vector iterator.

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
