create 2d array from 1 entry in another 2darray code example

Example 1: c fill 2d array

// Either
int disp[2][4] = {
  {10, 11, 12, 13},
  {14, 15, 16, 17}
};

// Or 
int disp[2][4] = { 10, 11, 12, 13, 14, 15, 16, 17};

// OR
int i, j;
for (i = 0; i < HEIGHT; i++) { // iterate through rows
  for (j = 0; j < WIDTH; j++) { // iterate through columns
    disp[i][j] = disp[i][j];
  }
}

Example 2: matrix c declaration

int disp[2][4] = { 10, 11, 12, 13, 14, 15, 16, 17};
