The associativity of an operator defines the order in which operators of the same precedence are grouped (right-to-left or left-to-right).
操作符的结合性定义了相同优先级操作符组合的顺序(从右至左或从左至右)。
Precedence or operator strength determines order of evaluation; an operator with higher precedence is evaluated before one of lower precedence.
优先级或者说操作符的强度决定求值顺序;优先级高的操作符比优先级低的操作符先求值。
Consider using parentheses to improve readability and avoid mistakes because of logical operator precedence.
考虑使用括号来改善可读性和避免由于逻辑操作符的优先级导致的错误。
If the character is an operator, pop operators until you reach an opening parenthesis, an operator of lower precedence, or a right associative symbol of equal precedence.
如果字符是个操作符,弹出(pop)操作符,直至遇见开括号(openingparenthesis)、优先级较低的操作符或者同一优先级的右结合符号。
