Note you will need to add copy constructor and assignment operator to the class as well as a destructor. WebMay 27, 2009 · 94. Since C99, C has 2D arrays with dynamical bounds. If you want to avoid that such beast are allocated on the stack (which you should), you can allocate them easily in one go as the following. double (*A) [n] = malloc (sizeof (double [n] [n])); and that's it. You can then easily use it as you are used for 2D arrays with something like A [i] [j].
