I have a class that has a vector<int> and I need to keep track of where in the vector array i am,
instead of making another variable called say int currentElement, which will keep track of where in the array i am i was wondering (and have looked but can't see) if vector class keeps it's own such variable.

Anyhelp greatly appreciated.

In these cases I usually just use a standard for loop instead of iterators.

Not exactly as you described, but like other standard library containers you can use iterators (alternative explanation) to iterate over the contents.

Note that if your compiler supports it C++11 added "range based for statements" (or "for each") syntax which allows for much cleaner and more readable code.


Is there some reason you need to store your position, or can iterate over all (or a subset) of the vector contents.

Hope that helps!

To answer your question jbadams...sry for late reply,
Ye the reason I wanted to keep track of my current position in the vector was because
the vector(2 vectors actually) holds the x and y positions on the map for an armys route from point a to b,
since the programs realtime and each army is processed every second I thought of keeping track which x'y they were at.
As it turned out I just delete the beginning (current) element every time they move so in the end I dont need to keep track of where in the vector they are since there always at vector.begin().

Your link is useful though and I thank you for your post.

Why not make an XY class holding both the x and the y, and have a "std::vector<XY> army_route" instead?

Well...I'm not sure why I'm not doing this,it's certainly going to make for cleaner code.
When I have a moment of "relaxed programming with a cup of tea" instead of "rushed programming with a jug of coffee" I should probably do this.
THX for the input
