C++ 此下一个\u组合代码的用法

目前，我正在尝试从包含一些整数的向量生成组合。现在，我希望它打印出所有长度为_生成的组合。 我在上找到了这段代码，它使用std:：next_置换来生成组合。下一个_组合代码如下所示：

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);
}

模板
bool next_组合（RandIt first、RandIt mid、RandIt last、comp比较）
{
排序（中间，最后，std:：tr1:：bind（comp，std:：tr1:：占位符：：）
，std:：tr1:：占位符：：_1））；
返回std：：下一个置换（第一个、最后一个、comp）；
}

我试着这样称呼它：

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 << " ";
        }
    }
}

bool mycop（int c1，int c2）
{return（c1），Compare=bool]'
