波兰和逆波兰表示法,确实如通常所说的,需要事先知道所有操作符 的参数数量。 Polish and Reverse Polish notation, as they are usually described, do require that all operators have a known arity. 当然,作为一个继续研究的话题,Rsc项目也欢迎大家的反馈,以及关于我们应该优化哪些操作符 组合的建议。 Of course, since this is an ongoing research, the Rsc project itself welcomes feedback or tips on what operator combinations we should optimize for. 在嵌入式系统中使用C++的一个常见问题是内存分配,即对new和delete操作符 的失控。 A common problem with using C++ in embedded systems is memory allocation, which is a loss of control over the new and delete operators . 是的,您确实需要了解语言基础,比如变量、循环、条件、操作符 等等; Yes, you do need to understand language basics, like variables, loops, conditionals, operators , and so forth; 虽然少见得多,a*1或a/1也会得到相同的结果,因为这些操作符 也是仅为数字操作定义的。 While far less common, a* 1 or a/ 1 would accomplish the same result, as those operators are also only defined for numeric operations.
操作符 是一种特殊的符号或短语,你可以用它来检查,改变,或组合值。An operator is a special symbol or phrase that is used to check, change, or combine values.此外,Kotlin的“==”操作符 不是比较引用,而是和equals方法一样。 Moreover, the operator '==' does not compare references in Kotlin, it works as the equals method. 当我们使用==操作符 时,它只会检查两者是否拥有相同的值。 I can use the operator == to verify if two entities have the same value. 操作符 AND和OR都是可交换的,也就是说,你可以交换左右操作数而不影响结果。The operators AND and OR are commutative, that is, you can switch the left and right operand without affecting the result.并不是一个操作符 ,实际上它是两个独立的操作符:--和>。 Well it is not an operator , it is a combination of two separate operators i.e.- and> 操作符 ,男孩知道,实际上是在主底盘,和只是用来贴上目标获取系统和武器。The operator , the boy knew, was actually in the main chassis, and the head was only used to affix target acquisition systems and armament.操作符 is和isnot比较两个对象是不是同一个对象,这只跟像列表这样的可变对象有关。The operators is and is not compare whether two objects are really the same object; this only matters for mutable objects like lists.操作符 是一种特殊的符号或短语,你可以用它来检查,改变,或组合值。An operator is a special symbol that you use to check, change or combine values.Unary operators operate on a single target(such as-a).操作符 name是一个最多NAMEDATALEN-1长的(缺省为31个)下列字符组成的字串:.The operator name is a sequence of up to NAMEDATALEN-1(31 by default) characters from the following list.但不是所有的CommonLisp操作符 都是函数,不过大部分是。 Not all the operators in Common Lisp are functions, but most are. 二元操作符 操作于两个目标(如2+3),是中缀操作符,因为它出现在两个目标的中间。 Binary operators operate on two targets(such as 2+ 3) and are infix because they appear in between their two targets. 在Asterisk1.0版本中的语法分析程序非常简单,所以它需要你在操作符 与任何其它值之间至少放一个空格。 In Asterisk version 1.0 the parser was quite simple, so it required that you put at least one space between the operator and any other values. 在你编写程序时,你会这么想:“我希望Lisp具有某某操作符 。 As you're writing a program you may think“I wish Lisp had such-and-such an operator .”. 操作符重载用于重载或重新定义C++中可用的大多数操作符 。 Operator overloading is used to overload or redefines most of the operators available in C++.
