1. Use the two methods (list of hash tables and hash table of lists) we introduced in class to design symbol tables. What are the symbol tables of the following example after processing the declarations "double a x" at line 6? Draw the graphs like the ones we show in slides 30 and 36 in lecture 08. Please apply the following scoping rules: (1) use "most closely nested" static scoping, (2) do not allow multiple declarations of a name in the same scope. (3) do allow the same name to be declared in multiple nested scopes, and (4) use the same scope for a method's parameters and for local variables declared at the beginning of the method. 1. int f (int a) { double x 2. 3. 4. 5. 6. 7. 8. while (...) { 9. } 10.} (1) List of hash table after processing line 6. (2) Hash table of lists after processing line 6. int X, Y if (...) { } double a, x 1. Use the two methods (list of hash tables and hash table of lists) we introduced in class to design symbol tables.
