2 dimensional array of chars.

Using Arduino Programming Questions

Thanks, I actually know that but I was trying to make sure it was very obvious what I was doing.

just looking for quick and/or smaller ways of doing stuff.

  for (int i = 0; i < 6; i++) {
    for (int k = 0; k < 20; k++) {
      commands[i][k]=(char)0;
    }
  }

As an example: To empty the array, is there an easier/smaller way of doing this?
