Are dollar-signs allowed in identifiers in C++03? covers that dollar signs in identifiers are not allowed in C++03. GCC provides it as a C extension and properly gives a diagnostic in C++03 mode. However, in C++11, int $ = 0 will compile without warning. This answer reasons that $ may be allowed because no diagnostic is required for implementation defined identifiers: The answer here is "Maybe" : According to §2.11 , identifiers may consist of digits and identifier-nondigits , starting with one of the latter. identifier-nondigits are the usual a-z , A-Z and underscore, in addition since C++11

I need to know the bundle identifiers for apple applications, such as mail, contacts, safari, photos, game center, settings, calendar, iPod, App store, camera, ...

Browsing the v8 tree, under the src directory, some js files were there, providing some basic JS objects like Math, Array etc. Browsing those files, I saw identifiers including a percent sign (%) in their names, i.e. %Foo . I first naively thought it was some other allowed character in JS's identifiers, but when I tried it in shell, it yelled at me, saying that I'm violating syntax rules. But if it is a syntax error, how come d8 works? Here are an example from the actual source code: src/apinatives.js lines 44 to 47, git clone from github/v8/v8 function Instantiate(data, name) { if (!

In C#, I can do the following: int @private = 15; And in VB.NET, I can do the following: Dim [Private] As Integer = 15 I am wondering if there is a way in F# to use reserved keywords as identifiers, like there is in VB.NET and C#? Jon Skeet Given section 3.4 of the F# 2.0 spec : Identifiers follow the specification below. Any sequence of characters that is enclosed in double-backtick marks (`` ``), excluding newlines, tabs, and double-backtick pairs themselves, is treated as an identifier. I suspect you can put it in backticks: ``private`` I haven't tried it though. 来源： https://stackoverflow

I'm working on a pre-written module for a site, and I need to target an element with the id test:two . Now, this element has a colon in it, so jQuery is presumably and understandably seeing the 'two' as a pseudo class. Is there any way of targeting this element with jQuery? Also, changing the ID is not possible. Believe me, if I could I would. I've put together an example: $('#test').css('background','red'); $(document.getElementById('test:two')).css('background','blue'); $('#test:two').css('background','green'); <script src="//code.jquery.com/jquery-1.6.3.js"></script> <div id="test">test<

I have been trying everything for hours, and nothing's worked. I am trying to segue between two view controllers, from one tableViewController to another tableViewController. The segue is hooked up to the top level view, not the tableviewcell. The identifier that was set in Xcode is identical to the one used in the code (copy and pasted). It was working fine last night, but now i can't seem to get it to segue without crashing. here are the methods in which the segue is called - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { self.photoList =
