forward_list::cbefore_begin() in C++ STLTo faithfully explain the concept of forward_list::cbefore_begin() in C++ STL. We first discussed the List in C++n programming language's code and output below. The forward list c before begin function is an in-built functionality in STL [Standard Template Library (STL)]. It returns a constant random-access iterator which points to the position before the first element of the forward_list. List in C++ STLC++ code Output: The List 1 has elements : 0 2 4 6 8 10 12 14 16 18 List 2 has elements : 27 24 21 18 15 12 9 6 3 0 list1.front() : 0 list1.back() : 18 list1.pop_front() : 2 4 6 8 10 12 14 16 18 list2.pop_back() : 27 24 21 18 15 12 9 6 3 list1.reverse() : 18 16 14 12 10 8 6 4 2 list2.sort(): 3 6 9 12 15 18 21 24 27 Syntax of forward_list::cbefore_begin()C++ code Output: the elements which have gotten inserted are as follows 10 20 30 40 50 Next TopicHeap in C++ STL | make_heap(), push_heap(),pop_heap(), sort_heap(), is_heap, is_heap_until() |
