Title
Chapter: 3 / Q: e.g3.6.1
We define an array whose elements are arrays by providing two dimensions: the dimension of the array itself and the dimension of its elements
Chapter: 3 / Q: e.g3.6.2
Multidimensional arrays may be initialized by specifying bracketed values for each row
Chapter: 3 / Q: e.g3.6.3
If we supply fewer subscripts than there are dimensions, then the result is the inner-array element at the specified index
Chapter: 3 / Q: e.g3.6.4
As another example, it is common to use a pair of nested for loops to process the elements in a multidimensional array
Chapter: 3 / Q: e.g3.6.5
Under the new standard we can simplify the previous loop by using a range for
Chapter: 3 / Q: e.g3.6.6
There is a deeper reason for using references. As an example, consider the following loop
Chapter: 3 / Q: e.g3.6.7
Because a multidimensional array is really an array of arrays, the pointer type to which the array converts is a pointer to the first inner array
Chapter: 3 / Q: e.g3.6.8
With the advent of the new standard, we can often avoid having to write the type of a pointer into an array by using auto or decltype (§ 2.5.2, p. 68)
Chapter: 3 / Q: e.g3.6.9
we can even more easily write this loop using the library begin and end functions (§ 3.5.3, p. 118)
Chapter: 3 / Q: e.g3.6.10
A type alias (§ 2.5.1, p. 67) can make it easier to read, write, and understand pointers to multidimensional arrays. For example
