C++ Algorithm Function copy()30 Aug 2024 | 1 min read C++ Algorithm copy() function is used to copy all the elements of the container [first,last] into a different container starting from result. SyntaxParameterfirst: It is an input iterator to the first element of the range, where the element itself is included in the range. last: It is an input iterator to the last element of the range, where the element itself is not included in the range. result: It is an output iterator to the first element of the new container in which the elements are copied. Return valueAn iterator to the last element of the new range beginning with result is returned. Example 1Output: newvector contains: 15 25 35 45 55 65 75 ComplexityThe complexity of the function is linear starting from the first element to the last one. Data racesSome or all of the container objects are accesed. ExceptionsThe function throws an exception if any of the container elements throws one. Next TopicC++ Algorithm copy_if Function |
C++ Algorithm reverse() C++ Algorithm reverse() function is used to reverse the order of the elements within a range [first, last). Syntax template <class BidirectionalIterator> void reverse (BidirectionalIterator first, BidirectionalIterator last); Note: BidirectionalIterator is an iterator which is used to access any elements of a container in both forward and...

C++ Algorithm reverse_copy() C++ Algorithm reverse_copy() function is used to copy the elements from the range[first, last) to another range beginning at result in such a way that the elements in the range are in reverse order. Syntax template <class BidirectionalIterator, class OutputIterator> OutputIterator reverse_copy (BidirectionalIterator first, BidirectionalIterator last, OutputIterator result); Note:...

C++ Algorithm remove_if() C++ Algorithm remove_if() function is used to eliminate all the elements that satisfy a predicate from a given range [first, last) without disturbing the order of the remaining elements. This function cannot alter the size of the container. It returns an iterator to the new end...

C++ Algorithm Functions copy_n() C++ Algorithm copy_n() function specifies the number of elements to be copied into the new container. The function is used to copy n elements of the container [first,last) into a different container starting from result. Syntax template<class InputIterator, class Size, class OutputIterator> OutputIterator copy_n(InputIterator first, Size...

C++ Algorithm Functions none_of() C++ Algorithm none_of() function returns a true value if the value of 'pred' argument is false. The value should be false for all elements in the range [first, last). Syntax template <class InputIterator, class UnaryPredicate> bool none_of (InputIterator first, InputIterator last, UnaryPredicate pred); Parameter first : It specifies...
