Question

Create an annotated parse tree for the string: 0101000
And what is the result of S.value?
Use the following Syntax Directed Translation:

Note: pos = position

Production
Semantic
List.pos = 3
S- List 100R
S.value = (List.value + 4) * 2R.Bit
R- R1 0
R.Bits = R1.Bits + 1
R.Bits = 0
%3!
List1.pos = List.pos + 1
Bit.pos = List.pos
List → List1 Bit
List.value = List1.value + Bit.value
List - Bit
Bit.pos = List.pos List.value = Bit.value
Bit → 0
Bit.value = 0
%3D
Bit → 1
Bit.value =
2Bit.pos
