And I'm declaring two dynamic arrays as I understand. What I
had in mind was declaring a dynamic array of two elements each.
int[2][] is exactly an dynamic array of (arrays with the length
2), the logic behind this notation is:
1. Array of 2 int -> int[2]
2. a dynamic array of 1. -> int[2][] (like SomeType[] is an array
of SomeType)
If you define SomeType e.g. as
struct SomeType {
int firstElement;
int secondElement;
}
you get something similar.
Yes, this is different from e.g. Java, where new int[2][42]
creates an array of 2 arrays with 42 elements each.
Accessing int[2][] nums :
1. nums[5] is the 5th element of nums which is of type int[2]
2. nums[5][0] is the zeroth element of 5th element of nums
int[2] tmp = nums[5];
int value = tmp[0];
does the same...
