Given is the task to show the working of forward_list::emplace_after() and forward_list::emplace_front() functions in c++.A forward_list only keeps linkage with the next element unlike normal list that keeps linkage with the next as well as the preceding elements, which helps iterations in both directions. But forward_list can only iterate in the forward direction.The forward_list::emplace_after() and forward_list::emplace_front() functions are a part of the c++ standard library.The forward_list::emplace_after() function is used to insert a new element inside a list after the element whose position is specified inside the argumentThe forward_list::emplace_front() function is used to insert an element in the beginning of the ...
