SLR5: Stages of Compilation

What is the first stage of the compilation process?

• Syntax Analysis

• Lexical Analysis

• Code Generation

• Code Optimisation

During lexical analysis, what is the term used for the smallest unit of meaning in the source code?

• Token

• Lexeme

• Identifier

• Keyword

Which of the following is NOT considered a valid token in programming languages?

• Keyword

• Constant

• White space

• Operator

What is the purpose of a symbol table in the compilation process?

• To store the source code

• To store tokens and their attributes

• To execute the program

• To optimise the code

What is the main task of the syntax analysis stage?

• To convert source code into tokens

• To check the syntactical structure of the code

• To generate machine code

• To optimise the code

What is an abstract syntax tree?

• A tree that represents the syntactical structure of the source code

• A table that stores all tokens

• A list of all errors in the code

• A diagram of the program's flow

Which of the following is a side effect of lexical analysis?

• Removal of syntax errors

• Removal of white space and comments

• Generation of machine code

• Creation of an abstract syntax tree

What is the role of the syntax analyzer in relation to the symbol table?

• To create the symbol table

• To update the data types of identifiers

• To remove duplicate entries

• To optimise the symbol table

What is the main output of the syntax analysis phase?

• Token stream

• Symbol table

• Abstract syntax tree

• Machine code

Which stage of compilation involves checking the syntax against production rules?

• Lexical Analysis

• Syntax Analysis

• Code Generation
