    UNIT 2:
    Syntax Analysis &Syntax Directed Translation
    Syntax analysis: CFGs, Top down parsing, Brute force approach, recursive descent parsing, transformation on the grammars, predictive parsing, bottom up parsing, operator precedence parsing, LR parsers (SLR,LALR, LR),Parser generation.Syntax directed definitions: Construction of Syntax trees, Bottom up evaluation of S-attributed definition, L-attribute definition, Top down translation, Bottom Up evaluation of inherited attributes Recursive Evaluation, Analysis of Syntax directed definition.

    UNIT 3:
    Type Checking & Run Time Environment
    Type checking: type system, specification of simple type checker, equivalence of expression, types, type conversion, overloading of functions and operations, polymorphic functions. Run time Environment: storage organization, Storage allocation strategies, parameter passing, dynamic storage allocation , Symbol table

    List of Experiments:

    Develop a lexical analyzer to recognize a few patterns.
    Write a programme to parse using Brute force technique of Topdown parsing.
    Develop LL (1) parser (Construct parse table also).
    Develop an operator precedence parser (Construct parse table also)
    Develop a recursive descent parser
    Write a program for generating for various intermediate code forms
    i) Three address code ii) Polish notation
    Write a program to simulate Heap storage allocation strategy
    Generate Lexical analyzer using LEX
    Generate YACC specification for a few syntactic categories.
    Given any intermediate code form implement code optimization techniques
