Consider the following union declaration:

This declaration illustrates that structures can be embedded within unions.

The following procedure (with some expressions omitted) operates on a linked list having these unions as list elements:

B. How many total bytes would the structure require?

C. The compiler generates the following assembly code for the body of proc:

On the basis of this information, fill in the missing expressions in the code for proc. Hint: Some union references can have ambiguous interpretations. These ambiguities get resolved as you see where the references lead. There is only one answer that does not perform any casting and does not violate any type constraints.
