// C++에 빠지다

#include <iostream>       
#include <queue>         
using namespace std;

int main()
{
	queue<int> hooQueue;
	
	hooQueue.push(18);
	hooQueue.push(21);
	hooQueue.push(23);
	hooQueue.push(27);
	hooQueue.push(31);

	cout << "The last element is " << hooQueue.back() << endl;
	cout << "The first element is " << hooQueue.front() << endl;

	hooQueue.pop();
	hooQueue.pop();

	cout << endl << "After pop funtion" << endl << endl;

	cout << "The last element is " << hooQueue.back() << endl;
	cout << "The first element is " << hooQueue.front() << endl;

	hooQueue.back() = hooQueue.back() + hooQueue.front();

	cout << "After add back and front elements: " << hooQueue.back() << endl;

	return 0;
}

The last element is 31
The first element is 18

After pop funtion

The last element is 31
The first element is 23
After add back and front elements: 54
