Give the equivalent C array expression for the following pointer expression assuming fubar is defined as an array. For this answer it does not matter what type each array element is or how many elements are defined. *fubar is equivalent to _____________________________ (equivalent array expression using [ ] but no *). #4. Using the Right-Left rule, define a variable named scary that is a pointer to a function that takes a single argument of type pointer to double and returns a pointer to a short.
