Little problem with STL

SDL Development
1

hi,

I’m playing with SDL, and I’ve a little problem with STD :slight_smile:

I’m using a vector, and when I push back, there’s no problem, but when I
want to push_front, the compiler said me : “no matching function for call
to…”.

Anyone has an idea?

thanx

This is nothing to do with the SDL libraries, so you’re asking in the
wrong place.

The answer is that std::vectors simply don’t have a push_front function
as it would be inefficient. If you need to insert at the front, use the
insert() member (and pay the efficiency penalty) or consider using an
std::deque or std::list.

Visit http://www.sgi.com/tech/stl/ for STL documentation.
And go to http://www.gamedev.net/community/forums (for example) to ask
questions like these.–

There are antibiotics to clear that sort of thing up, but you should
tell Ms. SDL that she should get checked by a doctor, too, in case she’s
the cause of your STD problem.

(Sorry, I couldn’t resist. What I meant to say was, “STL problems are off
topic for this list.”)

std::vector does not have a push_front method. In fact, such a method
probably wouldn’t be a good idea for a std::vector.

Perhaps you should give std::list a try.

Determining which STL object to use for a given problem can be fun. ;>
I’d recommend reading Scott Meyer’s “Effective STL” before doing any
serious STL programming.

Browsing comp.lang.c++ probably wouldn’t be a bad idea either (and
definitely a much better place to post STL related questions).

Finally, if you need a quick STL reference, check out these two sites:
