How to compile Bison flex?
Flex and Bison are tools for building programs that handle structured input.
They were originally tools for building compilers, but they have proven to be useful in many other areas..
What is Bison in compiler?
Bison is a general-purpose parser generator that converts an annotated context-free grammar into a deterministic LR or generalized LR (GLR) parser employing LALR (1) parser tables.
As an experimental feature, Bison can also generate IELR (1) or canonical LR(1) parser tables..
What is Flex and Bison in compiler design?
Flex (fast lexical analyzer generator) is a free and open-source software alternative to lex.
It is a computer program that generates lexical analyzers (also known as "scanners" or "lexers")..

What is Flex in compiler construction?
Types of Compiler
Cross Compilers.
They produce an executable machine code for a platform but, this platform is not the one on which the compiler is running.Bootstrap Compilers.
These compilers are written in a programming language that they have to compile.Source to source/transcompiler. Decompiler..What is Flex in compiler construction?
Compiler construction is a complex task.
A good compiler combines ideas from formal language theory, from the study of algorithms, from artificial intelligence, from systems design, from computer architecture, and from the theory of programming languages and applies them to the problem of translating a program..

What is the use of Flex and Bison?
Flex and Bison are tools for building programs that handle structured input.
They were originally tools for building compilers, but they have proven to be useful in many other areas..
- Bison by default generates LALR(1) parsers but it can also generate canonical LR, IELR(1) and GLR parsers.
Flex, an automatic lexical analyser, is often used with Bison, to tokenise input data and provide Bison with tokens.
Bison was originally written by Robert Corbett in 1985.
