You can access elements of an array by indices. you can't say numbers = 0x5a5aff23.More importantly the term decay signifies loss of type and dimension; numbers decay into int* by losing the dimension information (count 5) and the type is not int [5] any more. An array is a structure or container that holds a collection of items. C allows for arrays of two or more dimensions. A jagged array is an array of arrays, and therefore its elements are reference types and are initialized to null. You can iterate over the array or access individual items using an index.
