Multidimensional arrays

Nesting、containing、recursive-definition

1、Multidimensional arrays是典型的containing关系，我们是可以使用recursion来对它进行计算的；

2、multiple dimension array可以看做是array of array，因此，它是典型的recursive definition

stackoverflow n-dimensional c++ array. How`s that possible?

I find a library analogy very useful to visualizing arrays of multiple dimensions:

• 8-dimensional array is a library
• 7-dimensional array is a floor in a library
• 6-dimensional array is a room on a floor in a library
• 5-dimensional array is a bookcase in a room on a floor in a library
• 4-dimensional array is a shelf in a bookcase in a room on a floor in a library
• 3-dimensional array is a book on a shelf in a bookcase in a room on a floor in a library
• 2-dimensional array is a page in a book on a shelf in a bookcase in a room on a floor in a library
• 1-dimensional array is a line on a page in a book on a shelf in a bookcase in a room on a floor in a library
• 0-dimensional array is a character in a line on a page in a book on a shelf in a bookcase in a room on a floor in a library

stackoverflow Why use double indirection? or Why use pointers to pointers?
