Which operator has highest priority?
() operator has highest priority.
Operatorassociativity specifies whether, in an expression that contains multiple operators with the same precedence, an operand is grouped with the one on its left or the one on its right. Associativity is used when two operators of same precedence appear in an expression.
The associativity of an operator is a property that determines how operators of the same precedence are grouped in the absence of parentheses.
