Questions & Step-by-Step Solutions
What is the purpose of semantic rules in syntax-directed translation?
Step 1: Understand that syntax-directed translation is a method used in compilers to convert source code into another form, like machine code.
Step 2: Know that syntax refers to the structure or grammar of the programming language.
Step 3: Realize that semantic rules are guidelines that tell the compiler what to do with the information it gathers during parsing.
Step 4: Recognize that these rules help in performing actions like calculating values, checking types, or generating code based on the structure identified in the syntax.
Step 5: Conclude that the purpose of semantic rules is to ensure that the translation process is meaningful and correct, based on the syntax of the code.
