boost array使用

#include <iostream>
#include<boost/array.hpp>
int main()
{
	boost::array<int, 6> arr = {1,2,3,4,5,6};
	boost::array<int, 6> arr2 = {7,8,9,10,11,12};
	std::copy(arr.begin(), arr.end(), std::ostream_iterator<int>(std::cout, " "));
	std::cout<<std::endl;
	arr.swap(arr2);
	for(size_t i=0;i<arr.size();i++)
	{
		std::cout<<arr.at(i)<<" ";
	}
	std::cout<<std::endl;
	return 0;
}
