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>T</tt> is a model of <A href="EqualityComparable.html">Equality Comparable</A>.<LI>Objects of type <tt>T</tt> can be compared for equality with objects of <tt>InputIterator</tt>'s value 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 are not equal to <tt>value</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> comparisons for equality, and at most<tt>last - first</tt> assignments.<h3>Example</h3>Print all nonzero elements of a vector on the standard output.<pre><A href="Vector.html">vector</A><int> V;V.push_back(-2);V.push_back(0);V.push_back(-1);V.push_back(0);V.push_back(1);V.push_back(2);remove_copy(V.begin(), V.end(), <A href="ostream_iterator.html">ostream_iterator</A><int>(cout, "\n"), 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_if.html">remove_copy_if</A></tt>,<tt><A href="unique.html">unique</A></tt>, <tt><A href="unique_copy.html">unique_copy</A></tt>.<!--start footer--> <HR SIZE="6"><A href="http://www.sgi.com/"><IMG SRC="surf.gif" HEIGHT="54" WIDTH="54" ALT="[Silicon Surf]"></A><A HREF="index.html"><IMG SRC="stl_home.gif" HEIGHT="54" WIDTH="54" ALT="[STL Home]"></A><BR><FONT SIZE="-2"><A href="http://www.sgi.com/Misc/sgi_info.html" TARGET="_top">Copyright © 1999 Silicon Graphics, Inc.</A> All Rights Reserved.</FONT><FONT SIZE="-3"><a href="http://www.sgi.com/Misc/external.list.html" TARGET="_top">TrademarkInformation</A></FONT><P></BODY></HTML> ⌨️ 快捷键说明
