    A symbol table can just be an array of structs, eg.

    Code:
    typedef struct {
    	char *literal;
    	int value;
    } token;
    "literal" would be the actual representation, eg, "2+2" or "myfunc(arg)". "value" in that case would be "4" or whatever myfunc(arg) does.

    However, if you are new to C, why is it you need to know about symbol tables? AFAIK they are used in parsing, which is usually not a trivial task.
    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge

    More often than not they are hash tables on *nix systems, so Google 'em but if you are new to C you are starting at the wrong end.
