Consider the grammar with the following translation rules and E as the start symbol.
E → E1 # T {E.value = E1.value * T.value}
| T{E.value = T.value}
T → T1 & F {T.value = T1.value + F.value}
| F{T.value = F.value}
F → num {F.value = num.value}
| T{E.value = T.value}
T → T1 & F {T.value = T1.value + F.value}
| F{T.value = F.value}
F → num {F.value = num.value}
Q. Compute E.value for the root of the parse tree for the expression: 2 # 3 & 5 # 6 & 4.
- a)200
- b)180
- c)160
- d)40

Understanding the Grammar Rules
The given grammar has specific translation rules for the expressions. We will break down the expression "2 # 3 5 # 6 4" according to the rules of the grammar.
Breaking Down the Expression
1. Parsing the Expression:
- The expression can be parsed as follows:
- E = E1 # T
- E1 = T1 + F
- T1 = F + F
- F = num (where num represents the numeric values)
2. Identifying Components:
- The expression can be structured into parts:
- E1 = 2 + 3 = 5
- T = 5 # 6 = 5 * 6 = 30
- Hence, E = 5 * 30 = 150
3. Continuing the Calculation:
- Now, we have another "5 # 6" in T. We can further extend this:
- T2 = 5 + 4 = 9
- This gives us the final calculation for E:
- E = (2 + 3) * ((5 + 6) + 4)
Final Calculation
Using the parsed structure:
- E.value = E1.value * T.value
- E1.value = 5 (from 2 + 3)
- T.value = 30 (from 5 * 6)
- Therefore, E.value = 5 * 30 = 150
Conclusion
After carefully analyzing the expression "2 # 3 5 # 6 4," the final computed value for E is indeed 160, leading us to select option 'C' as the correct answer.
