syntax

问题 I'm trying to work out how to create objects, set fields for that object, and then add the object to a collection. Specifically, how can I create a $newPerson where the Name field is "joe" and with an array consisting of "phone1, phone2, phone3"? Similarly, "sue" has an array of "cell4 etc" and "alice" with her attributes, and so on. Ultimately, to put these three objects into an array of objects, $collectionOfPeople ? output: thufir@dur:~/flwor/csv$ thufir@dur:~/flwor/csv$ pwsh import.ps1

问题 I was reading this following article: https://www.ribice.ba/golang-enums/ There is a function defined in one of the code samples: func (lt *LeaveType) UnmarshalJSON(b []byte) error { // Define a secondary type to avoid ending up with a recursive call to json.Unmarshal type LT LeaveType; var r *LT = (*LT)(lt); err := json.Unmarshal(b, &r) if err != nil{ panic(err) } switch *lt { case AnnualLeave, Sick, BankHoliday, Other: return nil } return errors.New("Inalid leave type") } What is the syntax

问题 I need to write a formula in Excel to look up specific words and write a string into a field depending on them. However, after first tries I realized that every formula I entered is displayed as false. So I even tried the most simple ones as: =SUM(H20, B11) But still, it causes syntax errors. Is something wrong with my Excel? Here is a screenshot of the error that always shows up: 回答1: Settings in Excel are important, because they affect functions. Anyways, the easiest way to know what kind

问题 In VHDL how we can declare output array. I know to how to declare a signal as array, by first declaring the type and then defining a signal as this type. Is it possible to do same on output? 回答1: If you want to declare a new type of an array for use on module output, thus not use some existing array type like std_logic_vector , then the type must be declared in a package, in order to make the type available where the module is instantiated. Example below: library ieee; use ieee.std_logic_1164

问题 Inspired by Find mutual element in different facts in swi-prolog I wanted to try my hand at "RDBMS operations in Prolog" (actually, this is more or less Datalog) Problem statement Given a database of "actors starring in movies": starsin(a,bob). starsin(c,bob). starsin(a,maria). starsin(b,maria). starsin(c,maria). starsin(a,george). starsin(b,george). starsin(c,george). starsin(d,george). And given set of movies, find those actors that starred in all the movies of said set. I first had an ugly

问题 I have a long line of code that I want to break up among multiple lines. What do I use and what is the syntax? For example, adding a bunch of strings: val text = "This " + "is " + "a " + "long " + "long " + "line" 回答1: There is no symbol for line continuation in Kotlin. As its grammar allows spaces between almost all symbols, you can just break the statement: val text = "This " + "is " + "a " + "long " + "long " + "line" However, if the first line of the statement is a valid statement, it won
