geniusboy [140]

Answer:

When a method returns an array reference, you include ____ with the return type in the method header.
lisov135 [29]

Answer:

b. []

Explanation:

Arrays are represented using [] . When a method returns an array reference, the method header contains an entry of the type <data-type>[].

For example, a method test which returns a reference to integer array and takes no parameters is of the form:

int[] test();

Similarly a method list_chars which takes a String as an argument and returns an array of chars has the form:

char[] list_chars(String s);
