Question
Consider the grammar defined by the following production rules, with two operators and
Which one of the following is TRUE?
Which one of the following is TRUE?
Correct answer
(B) + is right associative, while is left associative
Solution
To determine associativity, we look at the recursion in the grammar productions:
1.For the operator : The production is . The non-terminal appears on the left side of the operator in the body of the production. This indicates left recursion, which corresponds to left associativity.
2.For the operator : The production is . The non-terminal appears on the right side of the operator in the body of the production. This indicates right recursion, which corresponds to right associativity.
Therefore, is right associative and is left associative.Continue learning with Success Tracker
