 It is possible to go ever further, and so a declaration like `data_type array_name[A][B][C]` is possible and would add more layers to your array. So after going through one layer, you have to input the location of the next layer, and so on and so forth until you reach the deepest layer of the `{}` where you'll find the object.

+## Restrictions
 
 1. The size is locked upon initialization. Once you make the array, its size is locked. For example, if you make a 2x3 array, and realize you need another column or row, you have to either make a new one, or change the size where you initialize it. If you want a dynamic size array, a array which you can change the size of, consider using `std::vector` instead.
 2. There is no way to search except by iterating through each object in the entire array. For example, if you need to find the number `2` in:
