Multidimensional irregular arrays
-------------can have several columns per row, but each column contains the same number.---------------------

int[][,] c=new int[][,]

{New int[,]{{1,3},{5,7}}, New int[,]{{2,4},{6,8}}, new int[,]{{0,10}, {20,30},{1000,2000}};
C[0][0,0]=1
c[2][2,1]=2000
------------------Array Differences--------------------------------------

Int[,] is a two-dimensional array, which is the traditional n x M table, and C + + int[][] is a meaning.

Int[][] is a jagged array, unlike the int[][in C + +. It is actually a int[] that is embedded in the int[], which can be understood as (int[]) []. You can see the illustrations I attached.
