I assume you mean "mat" here, to be consistent with what follows.

It's not. That's the first element of the first element.

That gives you the address of the first element. The first element is
an array of int of size 100.

It is like any other array. You just don't understand how it works. The
name of the array in most cir***stances is converted to a pointer to
the first element. So "mat" is of type "pointer to array 100 of int",
and points to the beginning of mat[0].

I recommend reading over the FAQ entries on pointers and arrays.
