void sort();	(1)	(начиная с C++11)
template< class Compare > void sort( Compare comp );	(2)	(начиная с C++11)

Сортировка элементов в порядке возрастания. Порядок равных элементов гарантированно будет сохранена. Первый вариант используется operator< для сравнения элементов, вторая версия использует данную comp функцию сравнения. Упорядочение эквивалентных элементов сохраняется.

Original:

Sorts the elements in ascending order. The order of equal elements is guaranteed to be preserved. The first version uses operator< to compare the elements, the second version uses the given comparison function comp. The ordering of equivalent elements is preserved.

Параметры

comp

-

comparison function which returns ​true if the first argument is less than the second. The signature of the comparison function should be equivalent to the following: bool cmp(const Type1 &a, const Type2 &b); The signature does not need to have const &, but the function must not modify the objects passed to it. Типы  Type1 и  Type2 должны быть таковы, что объект типа forward_list<T,Allocator>::const_iterator может быть разыменован и затем неявно преобразован в оба из них. ​

Пример

#include <iostream>
#include <functional>
#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.sort(std::greater<int>());
    std::cout << "descending: " << list << "\n";
}

Вывод:

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
