Question

Consider the following Three Address code sample for solving the questions:

$\begin{array}{lll}100 & : & t1= y+2 \\ 101 & : & \text{initial} = x/t1 \\ 102 &: & \text{limit} = 10 \\ 103 &: & \text{if } i >j \text{ goto }105 \\ 104 &: & \text{goto } 111 \\ 105 &: & \text{if } num > b \text{ goto } 107 \\ 
106 &:  & \text{goto } 111  \\ 107 &: & \text{num }= \text{ limit}-1 \\ 108 & : & b=y+2 \\ 109 & : & i=i - num \\ 
110 & : & \text{goto } 103 \\ 111 &: & j=i - num \\  112  & : & k= j+b \end{array}$

What all blocks does Block $3$ $\&$ Block $5$ dominate in the Flow graph for the TAC given in the passage?

• A. $\begin{array}{lll} \text{Block }3: 3 &;& \text{Block } 5: 5 \end{array}$
• B. $\begin{array}{lll}\text{Block }3: 3,4,5,6 & ; & \text{Block }5: 5,6 \end{array}$
• C. $\begin{array}{lll}\text{Block }3: 3,7 & ; & \text{Block }5: 5,7 \end{array}$
• D. $\begin{array}{lll} \text{Block }3: 3,4,7 &; & \text{Block }5: 5,6,7 \end{array}$
