Use make heap() and its buddies from algorithm>, or priority queue from queue>. 

Make heap and friends are used by priority queue.

#include <queue> // functional,iostream,ctime,cstdlib
using namespace std;

int main(int argc, char* argv[])
{
    srand(time(0));
    priority_queue<int,vector<int>,greater<int> > q;
    for( int i = 0; i != 10; ++i ) q.push(rand()%10);
    cout << "Min-heap, popped one by one: ";
    while( ! q.empty() ) {
        cout << q.top() << ' ';  // 0 3 3 3 4 5 5 6 8 9
        q.pop();
    }
    cout << endl;
    return 0;
}

What is the best way to use a HashMap in C++?

The ordered and unordered map containers (std::map and std::unordered map) are included in the standard library.  The items in an ordered map are sorted by key, and insert and access are in O (log n).  For ordered maps, the standard library often use red black trees.  However, this is only an implementation detail.  Insert and access are in O in an unordered map (1).  It is simply another term for a hashtable. An illustration using (ordered) std::map: #include <map> #include <iostream> #include <cassert> int main(int argc, char ...READ MORE
