    If I have an array, and want to make a heap tree out of it using make heap and sort heap, how would I do it? I'm struggling because I didn't take any course in data structure.

    I tried googling stuff and I got to the following:

    #include <algorithm> // for std::make_heap, std::sort_heap
    template <typename Iterator>
    void heap_sort(Iterator begin, Iterator end)
        std::make_heap(begin, end);
        std::sort_heap(begin, end);
    The thing is, I don't know what's the "Iterator" doing exactly and what's begin/end, how can I use arrays with the former piece of code?

    Any help -in c++- will be appreciated
