How to use the priority queue STL for objects

class Person
{
public:
    int age;
};

I'd want to put objects of the type Person in a priority queue.

priority_queue< Person, vector<Person>, ??? >

I believe I need to declare a class for the comparison, but I'm not sure.

In addition, when we write,

priority_queue< int, vector<int>, greater<int> >

How does the greater work?

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

how could I use the power function in c/c++ without pow(), functions, or recursion

It is part of a series. Replace pow() with the previous iteration's value. There is no need for code to call pow (). Pow(x, 5 * I - 1) and pow(-1, I - 1) may be formed since both have an int exponent dependent on the iterator I from the previous loop iteration. Example: Let f(x, i) = pow(x, 5 * i ...READ MORE
