How do you implement calculator in lex and yacc?
Create lex.l create yacc.y Compile using following: cc lex.yy.c yy.tab.c -ll -lm
Can you use yacc to generate a parser for HTML parsing?
Yes.
What you meant by yacc tool in compiler design?
Yacc provides a general tool for imposing structure on the input to a computer program. The Yacc user prepares a specification of the input process; this includes rules describing the input structure, code to be invoked when these rules are recognized, and a low-level routine to do the basic input. Yacc then generates a function to control the input process. This function, called a parser, calls the user-supplied low-level input routine (the lexical analyzer) to pick up the basic items (called tokens) from the input stream.
What is lex tool?
Lex is a parser generator tool. Its basically a program that generates the lexers.
What is the difference between technology and process?
what is the difference between license and patent
What is difference between Lex and Yacc?
lex is lexical analyser whereas yacc is a parser generator
What is lex and yacc?
My name is lex!
What are the lex and yacc complier for Windows?
Windows does not come with this software, and Microsoft does not provide an official version of it. If you want to use lex or yacc, you should try installing the Cygwin build environment. It is a free software collection that provides many Unix tools for Windows.
How do you implement calculator in lex and yacc?
Create lex.l create yacc.y Compile using following: cc lex.yy.c yy.tab.c -ll -lm
What is Lex and Yaac?
Lex can be defined as a program that helps write programs whose control flow is directed by instances of regular expressions in the input stream. Yacc can be defined as providing a tool for describing the input to a computer program.
What is lex and yacc in terms of unix operating system?
lex and yacc are two utility programs used primarily in Unix (but can be used in Windows as well, for example) that create files and code used by parsers and grammar checkers. You describe what the grammar should be and it creates a shell program that is capable of recognizing the grammar as being legal or not legal. These utilities can provide routines to parse, tokenize, and other tasks that would be too time consuming to do by hand.
What is a yacc?
Yacc is a computer program created for the Unix operating system. It is an acronym for "Yet Another Compiler ".

What are the names of tools used for fast implimentation of phases of compiler?
Lex and Yacc are two tools that are used to implement the first stages of compilation: tokenization (lexical analysis) and parsing. Free and Open Source versions of these tools are available called Flex and Bison.
Can you use yacc to generate a parser for HTML parsing?
Yes.
What are the applications of the computer program Yacc?
YACC, which stands for Yet Another Compiler Compiler, is considered a parser generator. This family of computer programs is used to decipher source code in programming. This type of program is used with almost all computer programs, but YACC has mostly been replaced by more recent programs.
What is yyin in yacc programs?
It is a file in which all input data is dumped .
