Questions & Step-by-Step Solutions

What is the output of a lexical analyzer typically used for?
  • Step 1: Understand what a lexical analyzer is. It is a tool that reads source code.
  • Step 2: Know that the lexical analyzer breaks the source code into smaller parts called tokens.
  • Step 3: Recognize that tokens are meaningful pieces of the code, like keywords, operators, and identifiers.
  • Step 4: Learn that the output of the lexical analyzer is a list of these tokens.
  • Step 5: Understand that these tokens are then sent to another tool called a parser.
  • Step 6: The parser uses the tokens to understand the structure and meaning of the code.
