This project consists of developing an interpreter for a minimal form (subset) of the Lua language. This minimal form of Lua has only 1 data type, integer, and the only identifiers are single letters. Lua is not case sensitive. The specification of the grammar is given below.

The interpreter will process a Lua program and build some intermediate data structures. These data structures will then be interpreted to execute the program. All tokens in this language are separated by white space. The parsing algorithm should detect any syntactical or semantic error. The first such error discovered should cause an appropriate error message to be printed, and then the interpreter should terminate. Run-time errors should also be detected with appropriate error messages being printed.
Question:
Develop a complete parser in C++ that executes with the scanner. You must show the execution of this program by using a relevant source line as input, the program must show the corresponding statement recognized. Write a short report describing the work performed.
