The returnvalue is the end of the resulting range. This operation is stable,meaning that the relative order of the elements that are copied is the same as in the range <tt>[first, last)</tt>.<h3>Definition</h3>Defined in the standard header <A href="algorithm">algorithm</A>, and in the nonstandardbackward-compatibility header <A href="algo.h">algo.h</A>.<h3>Requirements on types</h3><UL><LI><tt>InputIterator</tt> is a model of <A href="InputIterator.html">Input Iterator</A>.<LI><tt>OutputIterator</tt> is a model of <A href="OutputIterator.html">Output Iterator</A>.<LI><tt>InputIterator</tt>'s value type is convertible to a type in <tt>OutputIterator</tt>'s set of value types.<LI><tt>Predicate</tt> is a model of <A href="Predicate.html">Predicate</A>.<LI><tt>InputIterator</tt>'s value type is convertible to <tt>Predicate</tt>'s argument type.</UL><h3>Preconditions</h3><UL><LI><tt>[first, last)</tt> is a valid range.<LI>There is enough space in the output range to store the copied values. That is, if there are <tt>n</tt> elements in <tt>[first, last)</tt> that do not satisfy <tt>pred</tt>, then <tt>[result, result+n)</tt> is a valid range.<LI><tt>result</tt> is not an iterator in the range <tt>[first, last)</tt>.</UL><h3>Complexity</h3>Linear. Exactly <tt>last - first</tt> applications of <tt>pred</tt>, and at most<tt>last - first</tt> assignments.<h3>Example</h3>Fill a vector with the nonnegative elements of another vector.<pre><A href="Vector.html">vector</A><int> V1;V.push_back(-2);V.push_back(0);V.push_back(-1);V.push_back(0);V.push_back(1);V.push_back(2);<A href="Vector.html">vector</A><int> V2;remove_copy_if(V1.begin(), V1.end(), <A href="back_insert_iterator.html">back_inserter</A>(V2), <A href="binder2nd.html">bind2nd</A>(<A href="less.html">less</A><int>(), 0));</pre> <h3>Notes</h3><h3>See also</h3><tt><A href="copy.html">copy</A></tt>, <tt><A href="remove.html">remove</A></tt>, <tt><A href="remove_if.html">remove_if</A></tt>, <tt><A href="remove_copy.html">remove_copy</A></tt>,<tt><A href="unique.html">unique</A></tt>, <tt><A href="unique_copy.html">unique_copy</A></tt>.<!-- start footer --><!-- Footer Begins --><STYLE TYPE="text/css"><!--TD.footer, TD.footer A{ font-family: Arial, helvetica, sans-serif; font-size: 8pt;}A.home {font-family: Arial, helvetica, sans-serif;}--></STYLE><P><A CLASS="home" HREF="index.html">STL Home</A><P><TABLE WIDTH="600" CELLPADDING="0" CELLPADDING="0" BORDER="0"> <TR> <TD ALIGN="RIGHT" CLASS="footer"><A HREF="/company_info/terms.html" TARGET="_top">terms of use</A> | <A HREF="/company_info/privacy.html" TARGET="_top">privacy policy</A></TD> <TD ALIGN="CENTER" CLASS="footer"> | </TD> <TD ALIGN="LEFT" CLASS="footer"><A HREF="/cgi-bin/feedback/" TARGET="_top">contact us</A></TD> </TR><TR> <TD ALIGN="RIGHT" CLASS="footer">Copyright © 1993-2003 Silicon Graphics, Inc.
