Array of arrays with #include<array> in C++ : how can I create array of arrays with #include <array>?
My solution is 

        array<array<int, sze>, sze> arcpp { 0, 1, 2, 3 , 4, 5, 6, 7, 8, 9, 10, 11 
    ,12, 13, 14, 15 };
	for (auto i = 0; i < sze; i++) {
		cout << "\n";
		for (auto j = 0; j < sze; j++) {
			cout << "\t" << arcpp[i][j];
		}
	}
   

    
But I would like something like that:
	

    int matrix[][sze] = {
		{0, 1, 2, 3},
		{4, 5, 6, 7},
		{8, 9, 10, 11},
		{12, 13, 14, 15}
	};
