Even for didactical purposes, I would never start writing a parser in
C from scratch. You should use lex and yacc for that, unless your
language is a very simple regular language (e.g., no balanced
parentheses). The handling of context-free languages and LALR(1)
grammars is not straightforward and will almost certainly lead to
useless frustration, which you might not want to go through even if
you work as a language designer to bring bread on your table.

Parsing context-free grammars and has nothing to do with learning or
revising C, IMHO. My advice remain the same: code a simple shell, and
you will learn a lot more.
