How to initialize priority_queue with array values in C++

Answer 1

#include <iostream>
#include <queue>
 
int main()
{
    int arr[] = { 100, 88, 98, 80, 50, 12, 35, 70, 60, 97, 85, 89 } ;
    int size = sizeof(arr) / sizeof(arr[0]);

    std::priority_queue <int> pq(arr , arr + size) ;

    while (!pq.empty()) { 
        std::cout << pq.top() << " "; 
        pq.pop(); 
    }
}
 
 
 
 
 
/*
run:
  
100 98 97 89 88 85 80 70 60 50 35 12 
  
*/
