How to swap ranges between vector and deque in C++

Answer 1

#include <iostream> 
#include <vector>
#include <deque>
#include <algorithm>

using std::vector;
using std::deque;
using std::cout;  
using std::endl;

void print(int n) {
	cout << n << " ";
}

int main()
{
	vector<int> vec{ 13, 12, 300, 98, 81 };
	deque<int> dq{ 1, 2, 3, 4, 5 };
	
	swap_ranges(vec.begin() + 1, vec.end() - 1, dq.begin() + 1);

	for_each(vec.begin(), vec.end(), print);

	cout << endl;

	for_each(dq.begin(), dq.end(), print);

	cout << endl;

	return 0;
}
