Uso deste código next_combination
Atualmente, estou tentando gerar combinações de um vetor que contém alguns números inteiros. Por enquanto, quero que ele imprima todas as combinações de comprimento para gerar. Encontrei esse código emcombinação e permutação em C ++ que usa std :: next_permutation para gerar combinações. O código next_combination é o seguinte:
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);
}
Eu tentei chamar assim:
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 << " ";
}
}
}
mas recebo uma enorme mensagem de erro stl ilegível. Existe algo realmente óbvio dando errado aqui?
Quais cabeçalhos posso encontrar std :: placeholder?
Conforme solicitado, aqui está a mensagem de erro:
