Thread: Structure - Typedef accessing problem

Hi,

Code:

typedef enum RelationalOperators  {EQ, NE, GT, LT} Rel_Op;

Code:

typedef union TokenAttribute{
	Rel_Op rel_op;  
  } TA;

Code:

typedef struct Token
{
	TA attribute;
} Token;

Code:

token temp;

temp.attribute.rel_op[0];          /*error*/

i am trying to access the EQ, NE, GT, and LT to do certain operations afterwards - but cant seem to get the syntax right...

<<threads merged>>

Code:

typedef enum RelationalOperators  {EQ, NE, GT, LT} Rel_Op;


typedef union TokenAttribute{
	Rel_Op rel_op;  
  } TA;

typedef struct Token
{
	TA attribute; /* token attribute */
} Token;

Code:

Token temp;
temp.attribute.rel_op[0];       /*error*/

I have been trying ti access the rel_op as i need to compare the content...but cant seem to get the syntax right...

Is there something you're not telling us, because a union with only one member is a struct.
