The encoding of “Test String” is the implementation-defined system encoding (the narrow, possibly multibyte one). The encoding of u8″Test String” is always UTF-8. The examples aren’t terribly telling. If you included some Unicode literals (such as \U0010FFFF) into the string, then you would always get those (encoded as UTF-8), but whether they could be expressed … Read more
Yes, the lifetime of a local variable is within the scope({,}) in which it is created. Local variables have automatic or local storage. Automatic because they are automatically destroyed once the scope within which they are created ends. However, What you have here is a string literal, which is allocated in an implementation-defined read-only memory. … Read more
If we overloaded std::begin() and std::end() for const char arrays to return one less than the size of the array, then the following code would output 4 instead of the expected 5: #include <iostream> int main() { const char s[5] = {‘h’, ‘e’, ‘l’, ‘l’, ‘o’}; int i = 0; for (auto e : s) … Read more
In some .c file, write what you’ve written. In the appropriate .h file, write extern const char* QUERY; //just declaration Include the .h file wherever you need the constant No other good way 🙂 HTH
Your compiler ultimately operates on things called translation units, informally called source files. Within these translation units, you identify different entities: objects, functions, etc. The linkers job is to connect these units together, and part of that process is merging identities. Identifiers have linkage†: internal linkage means that the entity named in that translation unit … Read more
Derick has already mentioned that Jade added new feature for unescape HTML encoding in update, but I’d like to add some addendum for someone who might not recognize. – var html = “<script></script>” | !{html} <– Escaped | #{html} <– Encoded from https://github.com/visionmedia/jade
It’s a little bit of overkill, but one solution is to combine OverloadedStrings and RebindableSyntax. The RebindableSyntax extension causes all the implicit function calls that Haskell syntax uses to refer to whatever functions are in scope; for instance, integer literals use any fromIntegral, not necessarily Prelude.fromIntegral. As a side effect, Prelude is no longer implicitly … Read more
I would abstract it to a separate static class or resource completely: public static class MyStringResources { public static readonly string StringLiteral = @”This {0} a really long string literal I don’t want {1} to have {2} at the beginning of each line, so I have to break the indentation of my program”; } With … Read more
