Thread: One row per line?

Do you know what the output of this code would be? It should be outputting one row per line.

Code:

#include <iostream> 
#include <iomanip>

using namespace std;


int main()
{
    int matrix[4][3];

                                      
    
    int j, k;

    for (j = 0; j < 4; j++)
    {
        for (k = 0; k < 3; k++)
            matrix[j][k] = 2 * j + k;
            cout << matrix[j][k] << " ";

        cout << endl;
    }
}
