SLR 5 - Stages of Compilation

What is the first stage of the compilation process?

• Lexical analysis

• Syntax analysis

• Semantic analysis

• Code generation

What is removed during the lexical analysis process?

• Object code

• Logic errors

• Syntax errors

• Comments and white space

What is the purpose of tokenisation in lexical analysis?

• To identify the purpose of each element in the code

• To check the syntax of the code

• To generate object code

• To optimise the code

What does the syntax analysis stage check?

• That comments and white space are removed

• That tokens are in the correct order and follow language rules

• That object code is generated

• That the code is optimised

What is the main purpose of semantic analysis?

• To flag logic errors

• To generate object code

• To allocate tokens

• To remove comments

What is created during the code generation stage?

• Object code

• Source code

• Symbol table

• Tokens

What is a major distinguishing feature between compilation and interpretation?

• Compilation flags logic errors

• Compilation checks syntax

• Compilation removes comments

• Compilation produces a separate executable file

What does code optimisation aim to do?

• Check syntax

• Generate object code

• Remove comments

• Ensure the code runs as fast as possible

What is an example of dead code?

• A print statement after a return statement

• A variable assignment

• A loop

• A function call

What is the purpose of a symbol table in lexical analysis?

• To keep track of all elements identified in the program

• To generate object code

• To check syntax

• To flag logic errors
