template< class InputIterator, class OutputIterator, class T >
OutputIterator remove_copy( InputIterator first, | (1) | |
template< class InputIterator, class OutputIterator, class UnaryPredicate >
OutputIterator remove_copy_if( InputIterator first, | (2) | |
Copies elements from the range [first, last), to another range beginning at d_first, omitting the elements which satisfy specific criteria. The first version ignores the elements that are equal to value, the second version ignores the elements for which predicate p returns true.

Parameters
first, last | - | the range of elements to copy |
d_first | - | the beginning of the destination range |
value | - | the value of the elements not to copy |
Return value
iterator to the element past the last element copied.
Complexity
linear in the distance between first and last
Equivalent function
First version: |

template<class InputIterator, class OutputIterator, class T> OutputIterator remove_copy(InputIterator first, InputIterator last, OutputIterator d_first, const T& value) { for (; first != last; ++first) if (!(*first == value)) { *d_first++ = *first; } } return d_first; } |
Second version: |
template<class InputIterator, class OutputIterator, class UnaryPredicate> OutputIterator remove_copy_if(InputIterator first, InputIterator last, OutputIterator d_first, UnaryPredicate p) { for (; first != last; ++first) if (!p(*first)) { *d_first++ = *first; } } return d_first; } |
