注意DateAdd返回值 的格式由ControlPanel设置决定,而不是由传递到date参数的格式决定。 The format of the return value for DateAdd is determined by Control Panel settings, not by the format that is passed in the date argument.要从自定义函数返回值 ,您需要使用…等待它…返回关键字。 To return a value from a custom function, you need to use… wait for it… the return keyword.H(k)std::size_t返回值 在程序执行期间(C++14起)仅依赖于k的值。 H(k) std::size_t the returned value depends only on the value of k for the duration of the program(since C++14). If the function succeeds, the return value indicates the event that caused the function to return. . 很多函数只影响返回值 ,并且返回值仅取决于参数和全局变量。 Many functions have no effects except the return value and their return value depends only on the parameters and/or global variables.
以上所有的例子都没有返回任何值,但如果喜欢,可以从一个函数返回值 :. All the above examples are not returning any value, but if you like you can return a value from a function as follows. Compose1中的1表明复合函数和返回值 都只接受一个参数。 The 1 in compose1 indicates that the composed functions and returned result all take 1 argument. 如果一个方法有了类同样的名字但还有返回值 ,它不是构造器。 If a method has the same name as the class it is in, but also has a return type it is not a constructor. 因此,我们建立一个简单小巧的IfThenElseIf块以检查返回值 ,并回显一个更有意义的消息:. Therefore, we set up a simple little If Then ElseIf block to examine the returned value and echo back a more meaningful message. 事实上,你应该决不使用std::move将自动对象移出函数,因为这会禁止“命名返回值 优化”(NRVO)。 In fact, you should never use std::move to move automatic objects out of functions, as this inhibits the"named return value optimization"(NRVO). 而这个main()方法必须是共有的(public)、静态的(static)、返回值 为void,并且接受一个字符串数组作为参数。 The main() method must be public, static, return void, and accept one parameter: a String array. 今天(又)有人问我,为什么Python中的整除(integerdivision)返回值 向下取整(floor)而不是像C语言中那样向0取整。 I was asked(again) today to explain why integer division in Python returns the floor of the result instead of truncating towards zero like C. Int is the return type. The return value is None.Otherwise, the return value is meaningless. Return value only depends on its parameters.Returning more than one value from a function. ReduceRight返回值 是最后一次调用回调的返回值(10)。 The value returned by reduce would be that of the last callback invocation(10).Enode的返回值 ,请在另一个节点中运行以下命令。 Enode from one of the nodes, run the following command in the other node.Function就是必须要返回一个value;procedure则没有返回值 的硬性要求。 A function must have a return value, and a procedure cannot have a return value .
