In compiler design, why does semantic analysis follow syntax analysis?

A)To optimize code execution speed
B)To manage memory allocation efficiently
C)To resolve macro expansions early
D)To ensure type compatibility

💡 Explanation

Semantic analysis relies on the syntactical structure established by the syntax analyzer because it checks whether the program adheres to the language's rules about meaning. Therefore, type compatibility is verified, rather than optimizing or managing memory which occur in later compilation phases.
