NAME¶
std::forward_list::reverse - std::forward_list::reverse
Synopsis¶
void reverse() noexcept; (since C++11)
Reverses the order of the elements in the container. No references or
iterators
become invalidated.
Parameters¶
(none)
Return value¶
(none)
Complexity¶
Linear in the size of the container
Example¶
// Run this code
#include <iostream>
#include <forward_list>
std::ostream& operator<<(std::ostream& ostr, const
std::forward_list<int>& list)
{
for (auto &i : list) {
ostr << " " << i;
}
return ostr;
}
int main()
{
std::forward_list<int> list = { 8,7,5,9,0,1,3,2,6,4 };
std::cout << "before: " << list <<
"\n";
list.sort();
std::cout << "ascending: " << list <<
"\n";
list.reverse();
std::cout << "descending: " << list <<
"\n";
}
Output:¶
before: 8 7 5 9 0 1 3 2 6 4
ascending: 0 1 2 3 4 5 6 7 8 9
descending: 9 8 7 6 5 4 3 2 1 0
