Q: In syntax-directed translation, what is the role of semantic actions?
Solution: Semantic actions in syntax-directed translation are used to generate intermediate code based on the parse tree.
Steps: 5
Step 1: Understand that syntax-directed translation is a method used in compilers to convert source code into another form, like intermediate code.
Step 2: Recognize that a parse tree is a tree representation of the syntactic structure of the source code.
Step 3: Learn that semantic actions are specific instructions or operations that are executed during the translation process.
Step 4: Realize that these semantic actions are triggered at certain points in the parse tree.
Step 5: Understand that the purpose of these actions is to generate intermediate code, which is a simplified version of the original code that can be further processed.
