Assume the conflicts part (a) of this question are resolved and an LALR (1) parser is generated for parsing arithmetic expressions as per the given grammar. Consider an expression 3 # 2 + 1. What precedence and associativity properties does the generated parser realize? |
A. | of this question are resolved and an LALR (1) parser is generated for parsing arithmetic expressions as per the given grammar. Consider an expression 3 # 2 + 1. What precedence and associativity properties does the generated parser realize? a) Equal precedence and left associativity; expression is evaluated to 7 |
B. | Equal precedence and right associativity, expression is evaluated to 9 |
C. | Precedence of ‘x’ is higher than that of ‘+’, and both operators are left associative; expression is evaluated to 7 |
