Algorithm find the sum of the elements of the queue:

  1. Use the emplace() function to add elements to the queue.
  2. If a queue isn’t empty, add the front member to the sum variable before popping it.
  3. Continue in this manner until the queue is empty.
  4. The sum variable should be printed.
#include <queue>
#include <iostream>
using namespace std;

int main()
{
	// variable declaration
	int sum = 0;
	
	// queue declaration
	queue<int> myqueue{};
	
	// adding elements to the queue
	myqueue.emplace(70);
	myqueue.emplace(60);
	myqueue.emplace(40);
	myqueue.emplace(20);
	myqueue.emplace(70);
	myqueue.emplace(80);

	// queue becomes 70, 60, 40, 20, 70, 80

	// calculating the sum
	while (!myqueue.empty()) {
		sum = sum + myqueue.front();
		myqueue.pop();
	}
	cout<< sum;
}

Output:

34
