title: How do I store a matrix inside a row of another matrix in C++?
body: <p>My code is the following:</p>
  
  <pre><code>#define ROWS    3
  #define COLUMNS 3
  
  int main()
  {
      int fields[COLUMNS][ROWS];
      int **sudoku[COLUMNS][ROWS];
      sudoku[0][0] = fields;
  
      return 0;
  }
  </code></pre>
