UNIT -3 A Intermediate Languages and TAC Quiz

What is the purpose of an intermediate language in a compiler?

• To improve the efficiency of lexical analysis

• To simplify code generation

• To parse ambiguous grammars

• To eliminate semantic errors

Intermediate languages are generally:

• Machine-dependent

• Machine-independent

• Grammar-dependent

• Syntax-dependent

Which of the following is an example of an intermediate language?

• Assembly language

• Three-address code

• Binary machine code

• Context-free grammar

Why are intermediate representations used in compilers?

• They reduce parsing complexity

• They facilitate optimization and portability

• They eliminate the need for syntax analysis

• They replace machine code

Intermediate languages act as a bridge between:

• Source code and object code

• Syntax tree and parse tree

• Compiler and assembler

• Linker and loader

Which is a characteristic of intermediate code?

• It is always in binary format

• It is easy to optimize

• It replaces the need for source code

• It depends on specific hardware

Which of the following is NOT an intermediate representation?

• Syntax tree

• Quadruples

• Control flow graph

• Machine code

Which form of intermediate representation is most suitable for syntax-directed translation?

• Abstract syntax tree

• Three-address code

• Token stream

• Binary code

An intermediate language typically consists of:

• High-level constructs

• Low-level operations and addresses

• Natural language expressions

• Grammar rules

What is the main advantage of using intermediate languages?

• Speeds up parsing

• Simplifies the semantic analysis phase

• Makes the compiler portable and optimizable

• Improves the readability of source code
