Lets pretend you attend a 12 cinima movie threater. Inside one of the 12 cinimas you will find several rows of seats, each row contains any number of seats. That is a 2d array of seats

The indexing works the same way since it's nothing more than an array of 2D arrays. If you add another dimension of 2, duplicate what you posted each with an index of 0 and 1: 000 001 010 011 100 101 110 111.

Lets pretend you attend a 12 cinima movie threater. Inside one of the 12 cinimas you will find several rows of seats, each row contains any number of seats. That is a 2d array of seats

Now you can consider the entire cinima threater as a 3d array -- the first dimension represents each of the 12 cinimas, and inside each cinima is a 2d array of seats

So if you represent all the seats liks this

int const NumberCinimas = 12;
int const NumberRows = 15;
int const NumberSeatsPerRow = 20;

int Seats[NumberCinimas][NumberRows][NumberSeatsPerRow];

To assign a seat to someone you will need to know the cinima he wants to watch, and an empty seat in the desired row. So I can buy a ticket for cinima #3, row 15, seat 4

Seats[3][15][4] = AncientDragon;
