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
Correct answer is option 'C'. Can you explain this answer?

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.
