remove elements from vector

[Wing]

Hello,

I am thinking an efficient way to remove all the elements (says they
are less than 10) from a container vector<int>.

Any suggestion? Thank you.

Look into std::remove_if, std::less, std::bind2nd, and the erase-remove
idiom.

Any reason not to use std::vector::clear()?

Sounds like overkill if the OP wants to remove _all_ the elements.

I first read the question as "How does one remove all elements that are
less than 10?". I suppose it could be read as "How does one remove all
elements of a vector that has fewer than 10 elements?". Well, now the
OP has an answer either way.

Now I understand. I hadn't read the OP's question that way, but after
reading your interpretation I went back and reread the OP's question,
and now I see your point.
