13. Program Construction

Which stage of the compilation process is responsible for breaking source code into tokens?

• Syntax analysis

• Semantic analysis

• Lexical analysis

• Code generation

What is the main purpose of the symbol table during compilation?

• To store a list of error messages

• To hold variable and function names with associated data

• To generate binary code

• To perform optimisations

During which stage does the compiler check that constructs like loops, conditionals, and variable usage make logical sense according to language rules?

• Lexical analysis

• Syntax analysis

• Semantic analysis

• Code generation

Which of the following is performed during syntax analysis?

• Checking if variables have been declared

• Creating a parse tree from tokens

• Removing white space and comments

• Matching identifiers to memory addresses

Which stage of the compilation process transforms intermediate code into efficient machine code?

• Code generation

• Syntax analysis

• Semantic analysis

• Lexical analysis

During lexical analysis, source code is broken down into basic elements called __________.

The __________ table keeps track of variable names, data types, memory locations, and scope.

__________ analysis ensures that syntax rules, such as the correct order and nesting of statements, are followed.

__________ analysis checks for logical errors like using undeclared variables or type mismatches.

The stage of compilation that improves code efficiency without changing its output is known as __________.
