Which operator listed below has right to left associativity?

The operator that has right to left associativity is the assignment operator, often denoted by '='. Associativity refers to the order in which operators of the same precedence are evaluated in expressions. In programming languages, when you have multiple assignment operations in a single expression, they are evaluated from right to left.

For instance, if you have an expression like "a = b = c", this means that the evaluation happens as follows: first, the rightmost assignment (b = c) is evaluated, resulting in the value of 'c' being assigned to 'b', and then this result is assigned to 'a'. Hence, understanding that the assignment operator works with right to left associativity is essential for correctly predicting the behavior of compound assignments in programming.
