Question

When an array sales [5)[12] is declared without specifying initial values, what is the initial value of sales[0][0] ?(a) 0
(b) default value
(c) compilation error
(d) 60

Answer 1

When an array named sales of dimensions [5][12] is declared, without specifying any values, the initial value of sales[0][0] index is (b) Default value.

This default value is often called a garbage value, since this output of the index has no meaning, and has simply been entered by the computer to indicate that the array memory space is filled. When any variable or data structure such as array is declared, but not initialised, then garbage values are randomly generated and filled in the memory blocks of that respective index.
