В настоящее время я пытаюсь создать комбинации из вектора, который содержит несколько целых чисел. А пока я хочу, чтобы он распечатал все комбинации длины to_generate.
Я нашел этот код в комбинации и перестановку в C ++ , которая использует std :: next_permutation для генерации комбинаций. Код следующей_комбинации выглядит следующим образом:
template<class RandIt, class Compare>
bool next_combination(RandIt first, RandIt mid, RandIt last, Compare comp)
{
std::sort(mid, last, std::tr1::bind(comp, std::tr1::placeholders::_2
, std::tr1::placeholders::_1));
return std::next_permutation(first, last, comp);
}
Я пытался назвать это так:
bool mycomp (int c1, int c2)
{ return (c1)<(c2); }
void test_combos(int to_generate){
std::vector<int> combo(30);
for(int i=0;i<30;++i){
combo.push_back(i);
}
while(next_combination<std::vector<int>::iterator, bool>(combo.begin(),combo.begin()+to_generate,combo.end(),mycomp)){
for(std::vector<int>::iterator iter = combo.begin(); iter != combo.end() ; ++iter){
std::cout << *iter << " ";
}
}
}
но я получаю огромное искаженное сообщение об ошибке. Здесь что-то действительно не так?
Какие заголовки я могу найти std :: placeholder?
По запросу, вот сообщение об ошибке:
