The operators at the top of this list are evaluated first. 这些操作符从上倒下优先级递减! Associativity表示执行顺序 Precedence Operator Description Example Associativity 下面就不翻译了,大致讲对于一些系统不同导致的操作符优先级的实现不同,副作用吧。 One important aspect of C++ that is related to opera...
Operators that have the same precedence are bound to their arguments in the direction of their associativity. For example, the expressiona=b=cis parsed asa=(b=c), and not as(a=b)=cbecause of right-to-left associativity of assignment, buta+b-cis parsed(a+b)-cand nota+(b-c)because of...
and logical operators. Precedence levels determine the order in which MATLAB®evaluates an expression. Within each precedence level, operators have equal precedence and are evaluated from left to right. The precedence rules for MATLAB operators are shown in this list, ordered from highest precedence...
Expressions are constructed from operands and operators. The operators of an expression indicate which operations to apply to the operands. The order of evaluation of operators in an expression is determined by theprecedenceandassociativityof the operators. An operator usually has one or two operands....
Operator precedence is a set of rules that determines the order in which mathematical and logical operators are evaluated in an expression. Operators with higher precedence are evaluated first, while operators with lower precedence are evaluated later. In programming languages, the order of evaluation ...
Operator precedencedetermines how operators are parsed concerning each other. Operators with higher precedence become the operands of operators with lower precedence. Precedence And Associativity Consider an expression describable by the representation below. Note that both OP1and OP2are fill-in-the-blanks...

第二个堆栈使用GList打印空白 、、 我正在使用堆栈实现这个数据结构(从infix到后缀)。基本上,我测试的是推送和打印,没有弹出操作。第一个堆栈(即,stack )保存运算符和数字,而第二个堆栈stack_precedence记录优先级。我认为这两个堆栈都能正常工作,但我不明白为什么优先级堆栈没有打印优先级编号,而是返回空白输出。
