1. Lexical Analysis

2. • Lexical analysis is the process of breaking down a
string of characters into smaller units called tokens.
It's a fundamental step in natural language
processing (NLP) and in compiling computer
programs.

3. • How it works
• The lexical analyzer reads the input string of
characters
• It identifies tokens, such as keywords, operators,
punctuation, and constants
• It assigns strings to the tokens
• It removes any whitespace
• It generates an error if it finds an invalid token
• It passes the data to the syntax analyzer

4. • Benefits of lexical analysis
• It makes the source code easier for the computer to
understand
• It reduces the complexity of the source code for
parsing
• It facilitates better error handling by detecting and
reporting lexical errors early

5. • Drawbacks of lexical analysis
• It operates based on individual tokens and does not
consider the overall context of the code
• This can sometimes lead to ambiguity or
misinterpretation of the code's intended meaning
