Consider expression a = b * – c + b * – c. Convert it into Three address code andconstruct triple, Quadruple, Indirect Triples

To convert the expression a = b * – c + b * – c into Three address code, we need to break it down into smaller steps.

Step 1: Assign a temporary variable to the first multiplication operation. temp1 = b * – c

Step 2: Assign a temporary variable to the second multiplication operation. temp2 = b * – c

Step 3: Perform the addition operation using the temporary variables. a = temp1 + temp2

Now, let's construct the triple, quadruple, and indirect triples for this expression.

Triple:

1. (temp1, *, b, – c)
2. (temp2, *, b, – c)
3. (a, +, temp1, temp2)

Quadruple:

1. (temp1, b, – c, *)
2. (temp2, b, – c, *)
3. (temp1, temp2, +, a)

Indirect Triples:

1. (temp1, *, b)
2. (temp1, – c, *)
3. (temp2, *, b)
4. (temp2, – c, *)
5. (temp1, temp2, +, a)

These representations break down the expression into smaller operations and assign temporary variables to store intermediate results.
