An Error is the blank entries in the symbol table. The tasks of the Error Handling process are to detect each error, report it to the user, and then make some recover strategy and implement them to handle error. ![]() The output is dependent on the type of assembler. Target Code Generator : The main purpose of Target Code generator is to write a code that the machine can understand.Code Optimizer : It transforms the code so that it consumes fewer resources and produces more speed.Intermediate Code Generator : It generates intermediate code, that is a form which can be readily executed by machine We have many popular intermediate codes.It furthermore produces a verified parse tree. Semantic Analyzer : It verifies the parse tree, whether it’s meaningful or not.It takes all the tokens one by one and uses Context Free Grammar to construct the parse tree. Syntax Analysis : Syntax analyzer is also known as parser.Tokens can be identifiers, keywords, operators, separators etc. Lexical Analysis : Lexical analyzer reads a source program character by character to produce tokens.It helps the compiler to function smoothly by finding the identifiers quickly. Symbol Table : It is a data structure being used and maintained by the compiler, consists all the identifier’s name along with their types.
