Create an interpreter in your language $($java$,$ C$++,$ python$)$ that must perform

scanning and parsing of a given code

The program reads the code from a txt file.

The program scans the text file line by line generates tokens and displays the

tokens and their category $($identifiers$,$ keywords, assignment, number, add operator, multi$-$operator$).$

The program also checks the expression grammar based on calculator language given on slide number $20$ from Chapter $2.$

If the expression does not match the grammar it will display an error

You must submit the interpreter's complete code and a report either in pdf or word document. The report contains the code and the screenshot of the running program with the output.
