Question

Which ONE of the following statements is FALSE regarding the symbol table?

• A. Symbol table is responsible for keeping track of the scope of variables.
• B. Symbol table can be implemented using a binary search tree.
• C. Symbol table is not required after the parsing phase.
• D. Symbol table is created during the lexical analysis phase.

Hint:

The symbol table plays a critical role in managing variable scope and type information throughout the compilation process.

Answer 1

The Correct Option is C

The symbol table is essential throughout the compilation process. It helps in tracking the scope and attributes of variables. It is used during the lexical analysis phase, where identifiers are recorded.
It is also required during later phases like code generation.
Statement (C) is false because the symbol table is still necessary after parsing, during semantic analysis and code generation.
Therefore, the correct answer is \( \boxed{C} \).
