Uses recursive procedure calls to implement a stack abstraction.
The grammar must be left factored that means it should not have. Recursive descent parser encodes state information in its run-time stack, or call stack, and this may not be particularly efficient. For implementing a recursive descent parser for a grammar. Itcan be implemented easily by a hand-written program or by using one of the exist-ing parser generators such as DuW81, Gra88a, ReM85. In this type of parser, The concept of repeated reading of the input is called backtracking. Predictive Parser - Recursive Descent Parser (RDP) A parser that uses a set of recursive procedures to recognize its input with no backtracking is called a recursive descent parser. Recursive descent parsing is an established technique for the analysis of LL(1) languages since manyyears. Attributed grammars, Syntax directed translation, Conversion of popular programming languages language constructs into intermediate code forms, Type checker.Symbol Tables : Symbol table format, Organization for block structures languages, Hashing, Tree structures representation of scope information. The recursive descent parsing method is the general form or general way of representing top-down parsing. Here I rely on a ctitious computer, called Mini, as the target machine.
If you want an interpreter, a recursive descent parser will at the same time evaluate the expression, so there is no need to hold it in memory. Chapters 6 and 7 focus on the back end of the compiler (code generation and optimization).

Overview of Compilation : Phases of compilation - Lexical analysis, Regular grammar and regular expression for common programming language features, Pass and phases of translation, Interpretation, Bootstrapping, Data structures in compilation - LEX lexical analyzer generator.Top Down Parsing : Context free grammars, Top down parsing, Backtracking, LL (1), Recursive descent parsing, Predictive parsing, Preprocessing steps required for predictive parsing.Bottom up Parsing : Shift reduce parsing, LR and LALR parsing, Error recovery in parsing, Handling ambiguous grammar, YACC - automatic parser generator.Semantic Analysis : Intermediate forms of source programs - abstract syntax tree, Polish notation and three address codes. The answer to the question depends on whether you want a compiler, an interpreter, or something in between (an interpreter wrapped around an intermediate language).
