Understanding Compilation Options
Compilation is a multi-step process that transforms source code into executable code. Let’s evaluate the provided options:
Option A: The symbol table contains information about the lexical and the syntactical structure of the program.
- This statement is true. The symbol table is a crucial data structure in a compiler that holds information about identifiers (such as variables, functions, objects) used in the program. It maintains details like type, scope, and memory location, which contribute to both lexical and syntactical analysis.
Option B: The intermediate code generator does not use the symbol table.
- This statement is false. The intermediate code generator often relies on the symbol table to resolve identifiers and their attributes during code generation. It ensures that the generated code accurately represents the operations and data types defined in the source code.
Option C: The output of the semantic analysis is the annotated parse tree.
- This statement is true. Semantic analysis checks the parse tree generated during the parsing phase for semantic consistency (like type checking). An annotated parse tree is produced where additional information (like types) is attached to the nodes, aiding in further compilation phases.
Option D: The intermediate code generation and the machine code generation can never be combined in a single step.
- This statement is false. While many compilers separate these phases for clarity and modularity, some compilers do combine intermediate code generation and machine code generation to optimize performance, especially in just-in-time (JIT) compilers.
Conclusion
Thus, the correct options are A and C, as they accurately reflect the roles and outputs within the compilation process.

As we know,
Option (A):
The symbol table contains information about the lexical and syntactical structure of the program.
This is true about the compilation.
Option (B):
The intermediate code generator does use the symbol table.
This is false about the compilation.
Option (C):
The output of the semantic analysis is the annotated parse tree.
This is true about the compilation.
Option (D):
The intermediate code generation and the machine code generation can be combined in a single step.
This is false about the compilation.
Hence, the correct options are (A) and (C).
