Write an attribute grammar based on the CFG of Figure 4.11 that will build a syntax tree with the structure described in Figure 4.14. Augment the attribute grammar of Figure 4.5, Figure 4.6, or Exercise 4.21 to initialize a synthesized attribute in every syntax tree node that indicates the location (line and column) at which the corresponding construct appears in the source program. You may assume that the scanner initializes the location of every token.
