What is the difference between lexical and syntax analysis?

Lexical analysis is the process of converting a sequence of characters into a sequence of tokens, while syntax analysis checks the tokens against grammatical rules.

Can you give me an example of lexical analysis?

Sure! In the code int x = 10;, lexical analysis would identify int, x, =, and 10 as tokens.

And what about syntax analysis?

Syntax analysis would check if the statement follows the correct structure, like ensuring that the assignment is valid.

Why are both analyses important in programming?

Both analyses are crucial for compiling code correctly; lexical analysis breaks down the code, while syntax analysis ensures it adheres to language rules.
