Computing AST

[news.tkdsoftware.com]

Could someone show me a simple class structure example on how I'd approach
modeling my AST classes if my grammar was to parse a simple multiple
statement program which accepted statements in this format:

PRINT arithmetic_expression

So I could write a program that has:
PRINT 2+3*5
PRINT 6/3+2

Thanks in advance!

You might tell your instructor that you're having problems with the
homework assignment and ask him for help.

Please, please, don't use abbreviations.
What is your definition of an AST class?
A BLT could be a sandwich, a tree or a transformation.
For better communications, please define your abbreviations
before you use them or refrain from using them.

I suggest you discuss generic programming topics
