2. As a related challenge, revise that code to handle the case where
an intervening value in 'ARGV' is a variable assignment.
- 3. *note Walking Arrays::, presented a function that walked a
- multidimensional array to print it out. However, walking an array
- and processing each element is a general-purpose operation.
- Generalize the 'walk_array()' function by adding an additional
- parameter named 'process'.
-
- Then, inside the loop, instead of printing the array element's
- index and value, use the indirect function call syntax (*note
- Indirect Calls::) on 'process', passing it the index and the value.
-
- When calling 'walk_array()', you would pass the name of a
- user-defined function that expects to receive an index and a value,
- and then processes the element.
-
- Test your new version by printing the array; you should end up with
- output identical to that of the original version.
