Web1.Develop a lexical analyzer to recognize a few patterns in C. (Ex. identifiers, constants, comments, operators etc.). Create a symbol table, while recognizing identifiers. 2.Implement a Lexical Analyzer using Lex Tool. 3.Implement an Arithmetic Calculator using LEX and YACC. 4.Generate three address code for a simple program using LEX and YACC. WebThe intermediate code generation uses the structure produced by the syntax analyzer to create a stream of simple instructions. Many styles of intermediate code are. possible. One common style uses instruction with one operator and a small number of operands output of the syntax analyzer is some representation of a parse tree.

WebThere are the various phases of compiler: Fig: phases of compiler. Lexical Analysis: Lexical analyzer phase is the first phase of compilation process. It takes source code as input. It reads the source program one character at a time and converts it into meaningful lexemes. Lexical analyzer represents these lexemes in the form of tokens. Syntax ... WebTHE ROLE OF PARSER.
