Here are my codes, studies and experiments in general, which I performed using the tools for context-free grammar analysis. They are lex, yacc and bison.

Each directory is equivalent to a specific test. And to compile run the file compile-and-run.sh passing the directory name as a parameter.

./compile-and-run.sh "2 - filter tokens"

After compiling, just run the generated file with the name parsing, and type the input.

./parsing

For this example in question (using the 2 - filter tokens), a valid input could be:

10 20 30 A

For this input, the output will be:

type: INTEGER
token: 10

type: INTEGER
token: 20

type: INTEGER
token: 30

type: UNKNOWN
token: A

It is important to mention that within each directory there is a file called input.txt, which contain one (or more) possible example entries.
