increment

问题 This self-answered question addresses the scenario originally described in Increment version number in file: A version number embedded in a text file is to be incremented. Sample text-file content: nuspec{ id = XXX; version: 0.0.30; title: XXX; For instance, I want embedded version number 0.0.30 updated to 0.0.31 . The line of interest can be assumed to match the following regex: ^\s+version: (.+);$ Note hat the intent is not to replace the version number with a fixed new version, but to

问题 Quite new to this so I hope I have the terminology in the title right. I am trying to figure out how to create an instance method that will do the following: --An ID number is returned. --As each object is created from the class constructor(instantiated?), a unique integer ID number is assigned to it. The first ID number is 1, and as new objects are instantiated, successive numbers will be assigned. I am able to find examples of class/static methods that do the above however I am unable to

问题 This question already has answers here : Unexpected order of evaluation (compiler bug?) [duplicate] (3 answers) Closed 4 years ago . I'm new to C++ and study the increment and decrement operators. So I tried this example: int x = 4; cout << ++x << " " << x++ << " " << x++ << endl << endl; cout << x << endl; It returns this weird output on C++ .NET and QtCreator and 5 online C++ compilers: 7 5 4 7 The weird thing is that I expect something like this: 5 5 6 7 Can you explain what happens? 回答1:

问题 Ruby does not support incrementing variables like variable++ . I saw this behaviour that: 2 ++ 4 gives 6 . In fact, any number of + signs between two variables are treated as one single + . How does ruby manage that? And since ruby does that, can it be taken as the reason for the unavailability of the ++ operator? 回答1: This: 2 ++ 4 is parsed as: 2 + (+4) so the second + is a unary plus. Adding more pluses just adds more unary + operators so: 2 ++++++ 4 is seen as: 2 + (+(+(+(+(+(+4)))))) If

Please can someone explain to me why my addOne function doesn't work with the increment operator (++). Please see my code below. // addOne Function function addOne(num){ return num + 1 } log(addOne(6)) => 7 // same function with ++ operator function addOne(num){ return num++ } log(addOne(6)) => 6 // Question -

问题 I am making a small game using Slick2D and I run across an issue that makes my background move behind my character (who doesn't move). I'm not sure whether this is an issue with Slick or my code (probably the latter). The most frustrating thing about this issue is that it only occurs sometimes. With the exact same code it works perfectly, but it is completely unpredictable. Any ideas on what I can do? Here's my update method (There's some unfinished stuff in here regarding other aspects of

问题 So my goal for the program is for it to receive an Int matrix for input, and program converts all numbers > 0 to a unique sequential char, while 0's convert into a '_' (doesn't matter, just any character not in the sequence). eg. main> matrixGroupings [[0,2,1],[2,2,0],[[0,0,2]] [["_ab"],["cd_"],["__e"]] The best I've been able to achieve is [["_aa"],["aa_"],["__a"]] using: matrixGroupings xss = map (map (\x -> if x > 0 then 'a' else '_')) xss As far as I can tell, the issue I'm having is
