Consider the following statements about the use of backpatching in a compiler for intermediate code generation: (I) Backpatching can be used to generate code for Boolean expression in one pass. (II) Backpatching can be used to generate code for flow-of-control statements in one pass. Which ONE of the following options is CORRECT?

Backpatching is an intermediate code generation technique designed to resolve forward jumps in a single pass without needing a separate pass to resolve labels:

• Statement (I): Backpatching can be used to generate code for Boolean expressions (such as short-circuit evaluation) in one pass by maintaining lists of unresolved jump instructions (truelist and falselist) and filling in target labels when they become known.

• Statement (II): Backpatching can also be used to generate code for flow-of-control statements (like if-then, if-then-else, while, etc.) in one pass by maintaining a nextlist to patch branch targets when control reaches the subsequent code.

Therefore, both Statement (I) and Statement (II) are correct.

Hence, the correct option is (C).
