Example: get elements of 2d array c++

#include <array>
2 #include <iostream>

4 using namespace std;
5
6 //remember const!
7 const int ROWS = 2;
8 const int COLS = 3;
9
10 void printMatrix(array<array<int, COLS>, ROWS> matrix){
11 //for each row
12 for (int row = 0; row < matrix.size(); ++row){
13 //for each element in the current row
14 for (int col = 0; col < matrix[row].size(); ++col){
15 cout << matrix[row][col] << ' ';
16 }
17 cout << endl;
18 }
