How does a compiler use syntax and semantic analysis?

Can you explain how a compiler uses syntax analysis?

Sure! Syntax analysis checks the code structure against grammar rules to ensure it's correctly formed.

What happens during semantic analysis?

Semantic analysis verifies that the code makes sense, like checking variable types and ensuring operations are valid.

Why are both syntax and semantic analysis important?

Both are crucial for catching errors early. Syntax analysis ensures the code is well-structured, while semantic analysis ensures it behaves as intended.

Can you give an example of a semantic error?

Certainly! An example would be trying to add a string to an integer, which is not a valid operation in many programming languages.
