How does one initialize an array defined as
A[B][C] arr;
dynamically? (A,B,C are types, for example, int[int][string])
I want to store an array, indexed by strings, of ints, indexed by
ints.
For example, What I want is a hash map that maps integers to
integers so I can do something like
myval = arr[3243]; // has O(1) lookup
But then I want to be able to extend this to use strings to
subgroup the arrays:
myval1 = arr["Group1"][3243]; // has O(1) lookup
myval2 = arr["Group2"][3243]; // has O(1) lookup
so my arr definition is
int[int][string] arr;
Or, another way to see it, is I want the Key's to be strings and
the values to be int[int].
But when I try to access the value of the value I get an
exception, I believe, because I haven't initialized the value.
(because if I do a simple assign to the value it then works, but
I'm trying to check if the value exists in the first place)
I've also tried playing around with something like
int[string[int]] and reversing the order(IIRC the order has to be
backwards in the definition).
