Chapter 3, Problem 3.62HW

The code that follows shows an example of branching on an enumerated type value in a switch statement. Recall that enumerated types in C are simply a way to introduce a set of names having associated integer values. By default, the values assigned to the names count from zero upward. In our code, the actions associated with the different case labels have been omitted.

  The part of the generated assembly code implementing the differents actions is shown in Figure 3.52. The annotations indicate the argument locations, the register values, and the ease labels for the different jump destinations.

  Fill in the missing parts of the C code. It contained one case that fell through to another—try to reconstruct this.
