This string has the following format: > What do you think about the following code? Is there a better way? I would recommend learning how "real" parsers (e.g. those built using lex and yacc) work. Even though it's not really worthwhile using such tools for such a simple grammar, familiarity with state machines would probably be useful. If you ever need to parse a non-trivial grammar, you should definitely learn how real parsers work before constructing a "Rube Goldberg" parser out of dozens of "if"s and strcmp()s and even (and I've seen this in production code) fseek()s. > Did I forget something?
