Where are the shift/reduce conflicts in this Bison code coming from?

Question

I\'m trying to parse this syntax:

34 + 1 − 8, 32 * 87 + 6 / 4, 34 / 8

I\'m expecting to ground it like this:

(, (- (+ 34 1)         


        

Answer 1

You did not specify the priority of the operators like,

%left '+' '-'

%left '*' '/'

(in definition section)

Which can be the reason.
