Assign value to a Multy Dimentional Array

Projects Programming

Can I assign an array itself to an element like this, or how can I achieve this.

No
You can do

int cells[4][4] =
{
  {0, 1, 0, 1},
  {1, 0, 1, 0},
  {1, 1, 1, 1},
  {0, 0, 0, 0}
};

void setup()
{
  Serial.begin(115200);
  cells[1][0] = 1;
  cells[1][1] = 1;
  cells[1][2] = 0;
  cells[1][3] = 0;
}

Note that the array index for both dimensions starts at 0 not 1 as your attempted code might suggest.
