Hi,
I am using bison with flex (I am quite new with parsers).
I want to parse a grammar as given below:
char a = 'A'
int i = 5555
float f = 23.456
What is the best way to represent the grammar ?
1) declaration : datatype IDENTIFIER '=' CONSTANT;
datatype : CHAR
| INT
| FLOAT
2) declaration : CHAR IDENTIFIER '=' CHAR_CONST
| INT IDENTIFIER '=' INT_CONST
| FLOAT IDENTIFIER '=' FLOAT_CONST
In the (1) option above where do I parse what type of "CONSTANT" it is ?
The (2) option seems to be very verbose.
Regards.
