![]() whether the given input is in the correct syntax (of the language in which the input has been written) or not.It does so by building a data structure, called a Parse tree or Syntax tree.The parse tree is constructed by using the pre-defined Grammar of the language and the input string.If the given input string can be produced with the help of the syntax tree (in the derivation process),the input string is found to be in the correct syntax.ģ. It checks the syntactical structure of the given input,i.e. Syntax AnalyzerSyntax Analysis or Parsing is the second phase,i.e. It converts the input program into a sequence of Tokens.It can be implemented with the Deterministic finite Automata.Ģ. Lexical AnalyzerLexical Analysis is the first phase of compiler also known as scanner. Compiler-Design Aim : Design a C Compiler Course : Compiler Design Lab (CO351) Team : 1. ![]()
