Automatic Lexical Generator
The Automatic Lexical Generator is a tool that generates a code so that we can perform lexical analysis on that to get the output as tokens. This process is used in compiler design and in the field of computer science.
As we have discussed above the process of lexical analysis is to take the stream of characters and later convert it into tokens.
The Lexical Generator includes the following steps:
- In the first step, we give Lex source program as input to the lexical compiler and it will generate the Lex.yy.c files as output.
- In the second step, we take Lex.yy.c as input to the C compiler and it will generate the file a.out.
- And now the output file a.out will take the stream of characters and generates a sequence of tokens as an output.
Advantages of Automatic Lexical Generators
Lexical Generators help overcome many problems such as:
The main usage of Automatica Lexical Generators is to make Lexical analyzers for any language that too in an easy and efficient manner.
- Making a Lexical analyzer for any programming language is require the same level of design, coding, and practice to generate the output. In that case, Lexical Generator works efficiently.
- It is very difficult to make Lexical analyzers for every programming language as it is a very sophisticated process and with the help of Lexical generators we can solve that problem.
Automatic Lexical Generator
In this article, we are going to understand automatic lexical generators but before that, we have to understand what is Lexical analysis so let’s understand Lexical Analysis.
