Modern headers should be self-contained, which means that a program that needs to use the facilities defined by header.h can include that header (#include "header.h") and not worry about whether other headers need to be included first.
Recommendation: Header files should be self-contained...
Headers are a crucial consistency checking mechanism, but they should be
as small as possible.
In particular, that means that a header should not include other headers
just because the implementation file will need the other headers.
A header should contain only those headers necessary for a con...
Google's Include What You Use project, or IWYU, ensures source files include all headers used in the code.
Suppose a source file source.c includes a header arbitrary.h which in turn coincidentally includes freeloader.h, but the source file also explicitly and independently uses the facilities from ...
The C standard says that there is very little difference between the
#include <header.h> and #include "header.h" notations.
[#include <header.h>] searches a sequence of implementation-defined
places for a header identified uniquely by the specified sequence
between the &l...
If a singleshot timer is required, it is quiet handy to have the slot as lambda function right in the place where the timer is declared:
QTimer::singleShot(1000, []() { /*Code here*/ } );
Due to this Bug (QTBUG-26406), this is way is only possible since Qt5.4.
In earlier Qt5 versions it has to ...
The config location for your runner is:

Firstly, we set node category
let groundBody: UInt32 = 0x1 << 0
let boxBody: UInt32 = 0x1 << 1
Then add Ground type node and Box type node.
let ground = SKSpriteNode(color: UIColor.cyanColor(), size: CGSizeMake(self.frame.width, 50))
ground.position = CGPointMake(CGRectGetMidX(sel...
