Book I’ learning from claims that intArray has two dimensions. But since calling intArray.GetLength(1) will result in an IndexoutOfRange exception, couldn’t we claim that unlike rectangular arrays, intArray isn’t really multidimensional and thus has only one dimension?
int[][] intArray=new int[3][];
thank you
EDIT: BTW – I understand the difference between rectangular and jagged arrays
It does not have 2 dimensions. The syntax would be
int[,] intArray;. This is a jagged array (an array that contains arrays. It’s not square. For example, it might contain an array of size 2 and one of size 5.
