Use of 'const' for function parameters
...mation. You provide the parameter by value so the caller does not need to know anything on what you do (internally) with it. So write class Foo { int multiply(int a, int b) const; } in your header. In your implementation you do care that you can promise not to alter a and b so int Foo::multiply(cons...
What's the best way to put a c-struct in an NSArray?
...change at runtime. You're specifying a C type, which always must be fully known. If it could get "larger" by referencing more data, then you would probably implement that with a pointer, and the @encode would describe the structure with that pointer, but not fully describe the pointed-to data, which...
typedef struct vs struct definitions [duplicate]
...aration:
typedef struct bar {
int n;
} bar;
This is a common idiom. Now you can refer to this structure type either as struct bar or just as bar.
Note that the typedef name doesn't become visible until the end of the declaration. If the structure contains a pointer to itself, you have use th...
When do you use the “this” keyword? [closed]
...
Do you know how your answer sounds to me? Between the lines I read "How do you dare to ask a question like this?" - That is really not constructive in my opinion. No one knows everything - this is why we have Stackoverflow: To help ...
Can I pass an array as arguments to a method with variable arguments in Java?
...rraycopy(arr, 0, arr, 1, N);
arr[0] = firstElement;
return arr;
}
Now you can do the following:
String[] myArgs = { "A", "B", "C" };
System.out.println(ezFormat(append(myArgs, "Z")));
// prints "[ A ][ B ][ C ][ Z ]"
System.out.println(ezFormat(prepend(myArgs, "Z")));
/...
What is the advantage of using forwarding references in range-based for loops?
...This last case of mine should really be a template to make sense. If you know the loop is always handling a proxy reference, then auto would work as well as auto&&. But when the loop was sometimes handling non-proxy references and sometimes proxy-references, then I think auto&& wou...

How to move files from one git repo to another (not a clone), preserving history
... what if your file has moved through several directories, and now resides in one--will subdirectory-filter still work? (i.e. I'm assuming that if I just want to move one file, I can move it to its own subdirectory and this will work?)

How to get string objects instead of Unicode from JSON?
...e a conversion function:
I used the one from Mark Amery a couple of times now, it works great and is very easy to use. You can also use a similar function as an object_hook instead, as it might gain you a performance boost on big files. See the slightly more involved answer from Mirec Miskuf for th...
Why do we need tuples in Python (or any immutable data type)?
...ding a tuple is over 7.6 times faster than building the equivalent list -- now you can't say you've "never seen a noticeable difference" any more, unless your definition of "noticeable" is truly peculiar...
