Imagine the following declaration:And a second one:What are the possible performance differences between these two if any? And is there any danger associated with any of these solutions?

Consider following code:I have here two arrays one is with static keyword the second is within function. How should I properly name each of them? Because those two are static. I know the difference that tab array will exist forever unlike tab2 which exists only when executing function foo(). If...
Why does this code return a warning warning: ISO C++ forbids converting a string constant to ‘char*’ [-Wwrite-strings]
Arrays don't have a "toList" function, so we need "Arrays.asList" helper functions to do the conversion.
I have a C# static class accessed from multiple threads. Two questions:Usage of static class from different threads:
Quick context: I'm seeing errors on program shutdown, that stem from dependencies between global members (::sigh::, I know, I know). One global variable's destructor might refer to another global -- and if that one's already been destructed, things get bad.
I have two questions. Firstly, consider the below code.When I run this code it gives me below outputCan any one elaborate why INNER is null and execution flow at a time when exactly "A" & "B" added to collection?
Static local variables are initialised on the first function call:Variables declared at block scope with the specifier static have static storage duration but are initialized the first time control passes through their declaration (unless their initialization is zero- or constant-initialization, which can be performed before the block is first entered)....
I have this extremely trivial piece of C code:I understand that the first statement is illegal (I've declared a global array with no specified size), but why is it resulting in a linker error? :
