public member function
<forward_list>
Reverse the order of elements
Reverses the order of the elements in the forward_list container.
Example
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
|
// reversing forward_list
#include <iostream>
#include <forward_list>
int main ()
{
std::forward_list<int> mylist = {10, 20, 30, 40};
mylist.reverse();
std::cout << "mylist contains:";
for (int& x: mylist) std::cout << " " << x;
std::cout << std::endl;
return 0;
}
|
Output:
mylist contains: 40 30 20 10
|
Complexity
Linear in container size.
Iterator validity
All the iterators, pointers and references remain valid after the reversal and refer to the same elements they were referring to before.
