Title: Difference between list and list::iterator
Post by: Bizarreofnature on October 25, 2017, 05:12:29 pm

Hello there!

I hope this is the right section for my question. However:

What exactly is the difference between a list and list::iterator?
And when do I use those?

EDIT: And what is the difference between "remove" and "erase" ?

Thanks in advance,
Bizarreofnature

That is a C++ question. This is the SFML forum. For C++-only questions it is advised to seek another forum to post at.

Neverthless, regarding your questions, you ought to read something about STL containers. Meanwhile read here: http://www.cplusplus.com/reference/iterator/ and http://www.cplusplus.com/reference/list/list/

Thank you for your answer.

I see. I am sorry about posting it in the wrong forum, I just did because it directly affects my Game that I code.

So a list contains objects and an iterator is used to work them off piece by piece.

May I be allowed to ask a last question, even if it is the wrong forum.

Remove just removes objects from the list but erase destroys them?
