I am reading this **C** code, and I find it difficult to understand what's going on.

Here is the array:

```
static const char   gradient[32][4] =
{
{ 1,  1,  1,  0}, { 1,  1,  0,  1}, { 1,  0,  1,  1}, { 0,  1,  1,  1},
{ 1,  1, -1,  0}, { 1,  1,  0, -1}, { 1,  0,  1, -1}, { 0,  1,  1, -1},
{ 1, -1,  1,  0}, { 1, -1,  0,  1}, { 1,  0, -1,  1}, { 0,  1, -1,  1},
{ 1, -1, -1,  0}, { 1, -1,  0, -1}, { 1,  0, -1, -1}, { 0,  1, -1, -1},
{-1,  1,  1,  0}, {-1,  1,  0,  1}, {-1,  0,  1,  1}, { 0, -1,  1,  1},
{-1,  1, -1,  0}, {-1,  1,  0, -1}, {-1,  0,  1, -1}, { 0, -1,  1, -1},
{-1, -1,  1,  0}, {-1, -1,  0,  1}, {-1,  0, -1,  1}, { 0, -1, -1,  1},
{-1, -1, -1,  0}, {-1, -1,  0, -1}, {-1,  0, -1, -1}, { 0, -1, -1, -1},
};

```

and it's 32\*4, this is another part of the code that trying to access this array:

```
const char * g0000 = gradient[Indice (x1, y1, z1, t1)];

```

`Indice` is a function that returns an `int`. So what is this `g0000` (I know it's a pointer), say `Indice` returns 1, what is the value `g0000` holds? I mostly code in **C#** to my understanding if you want to access multidimensional array you would need several arguments, but here is only one, I am really confused...
