このnext_combinationコードの使用

Question

現在いくつかの整数を含むベクトルから組み合わせを生成しようとしています。今のところ、to_generateの長さの組み合わせをすべて印刷したいと思っています。 このコードは、std :: next_permutationを使用して組み合わせを生成するcombination and permutation in C++にあります。次のようにnext_combinationコードは次のとおりです。

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); 
} 

私はこのようにそれを呼び出そうとしました：

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 << " "; 
     } 
    } 
} 

が、私は巨大なSTL文字化けエラーメッセージが表示されます。ここで間違っていることが本当に明白なことはありますか？

std :: placeholderはどのヘッダを見つけることができますか？

要求されたとして、ここではエラーメッセージは次のとおりです。

Answer 1

第2のテンプレート引数はboolすべきではありません。コンパイラにタイプを処理させ、単に次のように書くことができます。

while(next_combination(combo.begin(), combo.begin() + to_generate, combo.end(), std::less<int>())) 
    for(std::vector<int>::iterator iter = combo.begin(); iter != combo.end() ; ++iter) 
     std::cout << *iter << " "; 

そしてスペースを使用すると、コードがより見やすくなります。
