A fast method to round a double to a 32-bit int explained

...N
(
SELECT TOP 2 ID, PERIOD,QTY

ORDER BY CAST(PERIOD AS DATE)DESC
)D
ON M.ID=D.ID

The above query generates the following result.

Passing a 2D array to a C++ function
... You should use %p for printing a pointer, and even then, you must cast it to void *, else printf() invokes undefined behavior. Furthermore, you should not use the addressof (&) operator when calling the functions, since the functions expect an argument of type double (*)[size_y], wherea...
Generate random numbers using C++11 random library
...e Breymann (2015) still use a clone of
srand( time( 0 ) );
srand( static_cast<unsigned int>(time(nullptr))); or
srand( static_cast<unsigned int>(time(NULL))); or
just with <random> instead of <time> and <cstdlib> #includings - so be careful to learn just from one bo...
What's the best way to put a c-struct in an NSArray?
...tableArray *)arrayRef;
struct {int member;} myStruct = {.member = 42};
// Casting to "id" to avoid compiler warning
[array addObject:(id)&myStruct];
// Hurray!
struct {int member;} *mySameStruct = [array objectAtIndex:0];
The above example completely ignores the issues with respect to memory...
Can I pass an array as arguments to a method with variable arguments in Java?
...rgument to method x(X...) doesn't exactly match the vararg parameter type. Cast to X[] to confirm the non-varargs invocation, or pass individual arguments of type X for a varargs invocation.

Abstract class in Java
...
If we wish to access a member specific to a particular subclass, we must cast down to that subclass first:
// Say ImplementingClass also contains uniqueMethod()
// To access it, we use a cast to tell the runtime which type the object is
AbstractClass b = new ImplementingClass();
((ImplementingCla...
