As others have mentioned, Annex D of ISO/IEC 9899:2011 lists the hexadecimal values of characters valid for universal character names in C11. (I won’t bother repeating it here.) I have been searching for an answer as to “why” this list was chosen. Character set standards First, there are two relevant standards defining a set of … Read more
You can use header files. Good practice. You can create a file called player.h declare all functions that are need by other cpp files in that header file and include it when needed. player.h #ifndef PLAYER_H // To make sure you don’t declare the function more than once by including the header multiple times. #define … Read more
I advice you to read the official blog of the best practice of google to see what the use case match with your specification : https://developer.android.com/training/articles/user-data-ids.html For me i occcured the same problem about the unicity of android identifiers and i found the only solution is to use the MediaDrm API ( https://android.googlesource.com/platform/frameworks/base/+/android-cts-4.4_r1/media/java/android/media/MediaDrm.java#539 ) which … Read more

The apostrophe is just part of the name. It is a naming convention (idiom) adopted in Haskell. The convention in Haskell is that, like in math, the apostrophe on a variable name represents a variable that is somehow related, or similar, to a prior variable. An example: let x = 1 x’ = x * … Read more
This is implementation defined behavior, $ is not included in grammar for identifiers. The rules for identifier names in C++11 are: It can not start with a number Can be composed of letters, numbers, underscore, universal character names and implementation defined characters Can not be a keyword Implementation-defined characters are allowed and many compilers support … Read more
You ask: Is there a command that can change this maximum length? Is this length the same for other names (columns, tables etc)? The manual answers here: The system uses no more than NAMEDATALEN-1 bytes of an identifier; longer names can be written in commands, but they will be truncated. By default, NAMEDATALEN is 64 … Read more
(I think it’s pretty cool too, that might mean we’re geeks.) You’re fine to do this with the code you have above in Python 3. (It works in my Python 3.1 interpreter at least.) See: http://docs.python.org/py3k/reference/lexical_analysis.html#identifiers http://www.python.org/dev/peps/pep-3131/ But in Python 2, identifiers can only be ASCII letters, numbers and underscores. http://docs.python.org/reference/lexical_analysis.html#identifiers
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.
It is not technically valid JavaScript. These are calls to V8 runtime functions. From that page: Much of the JavaScript library is implemented in JavaScript code itself, using a minimal set of C++ runtime functions callable from JavaScript. Some of these are called using names that start with %, and using the flag “–allow-natives-syntax”. Others … Read more
