Removing elements from Vector

The ''opposite'' of push_back() is (logically) pop_back(). This limits you to LIFO data management, though (after all, push and pop are stack operations).

The access violation you''re getting is probably when you reach the end of the vector. Remember to put in a check for vector.end()!

If you want to remove all the elements, use clear().

For efficiency''s sake, however, you may want to have a ''deleted'' flag for the items, restrict yourself to pop_back(), or use another storage class - vectors don''t deal well with deletions anywhere except the end.

ok thanks...
so should I be using vector if I want to delete things from half way through?
Also, do I need to delete the objects as well as pop them?

*poke*

If you are not holding pointers in your vector, you do not need to delete the item.
Use a list if you are going to be removing items and adding items anywhere in the list often.
for vector I think iterators are invalidated after a remove / erase operation, so make sure you get new iterators after a remove / erase.

ok thanks risingdragon3.
and yes I am storing pointers in my list.
