     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}" !
