问题 When compiling an executable in Release mode -with code optimizations enabled- the compiler may opt to inline functions that meet certain criteria in order to improve performance. My question is this: when an exception is thrown in the body of a function that has been inlined, will the stacktrace information be preserved regardless of the inline expansion? In other words, will it show the original function as the source of error, or will it show the calling function instead? 回答1: It depends

问题 C++17 allows static member variables to be defined thus: class X { public: static inline int i = 8; }; What is the rationale behind requiring the inline specification? Why not simply allow programmers to write static int i = 8; in the class? 回答1: Without inline , it's explicitly stated as only a declaration. As specified in [class.static.data]/2 The declaration of a non-inline static data member in its class definition is not a definition and may be of an incomplete type other than cv void.

问题 Which formatter VCode uses? I read somewhere VC uses jsbeautifier so I tried adding a compatible ignore comment to my .ejs template, but to no avail. 回答1: As far as I know, there is no way to do this without an extension. However, you have full control of the formatting if you use this extension. It also uses js-beautify, but it adds configuration. As specified in the js-beautify docs, the "preserve" directive only works in javascript sections. I have tested this in the script tag of an ejs

问题 Will any function defined in the header file automatically be inline? If I declare a function in a class and give the definition outside using keyword inline, will this function be inline? If it is, why this does not against the law that inline function should be given the body at declaration? 回答1: Any function defined inside a class definition is inline. Any function marked inline is also inline. class C { int f() { return 3; } // inline int g(); int h(); } inline int C::g() { return 4; } //
