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 difference between dynamic (C# 4) and var?
...can infer types that might not be desired because of subtypes and implicit casts. That is, var may have resolved a type statically different than expected when implicit casts occur (most notably to a more general type, but it's not limited to this). A trivial example is object x = "" vs. var x = "" ...
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...
A fast method to round a double to a 32-bit int explained
...e problem of getting that result into an integer variable without the slow cast. (There's also nothing C++-specific about your code.)

What is a C++ delegate?
...). I have yet to see an implementation which does not use wild reinterpret_casts, Nested class "prototypes" which hopefully produce function pointers of the same size as the one passed in by the user, compiler tricks like first forward declare, then typedef then declare again, this time inheriting f...
Cannot set some HTTP headers when using System.Net.WebRequest
...cause of multiple ways to do this. When using WebRequest.Create() you can cast to an HttpWebRequest and use the property to add or modify a header. When using a WebHeaderCollection you may use the .Add("referer","my_url").
Ex 1
WebClient client = new WebClient();
client.Headers.Add("referer", "ht...
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.

Java Interfaces/Implementation naming convention [duplicate]
...Truck.
When you are using the Interface in place of a sub-class you just cast it to Truck. As in List<Truck>. Putting I in front is just Hungarian style notation tautology that adds nothing but more stuff to type to your code.
All modern Java IDE's mark Interfaces and Implementations and ...
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...
