If this is exactly your program:
> digit [0-9]
> digits {digit}+
> whitespace [ \t\n]+
>
> %%
> "[" { printf("open_brac\n");}
> "]" { printf("close_brac\n");}
> "+" { printf("addop\n");}
> "*" { printf("multop\n");}
> {digits} { printf("NUMBER = %s\n", yytext);}
> whitespace ;
then the problem is that the last rule needs to be "{whitespace}" !
