Casting eof to (char) is a bit dodgy, suggesting some kind of relevance and universality which is illusory. For some possible values of eof() and signed char, it will give implementation-defined results. Directly using e.g....
Why doesn't java.util.Set have get(int index)?
...tem, I can
use set.iterator().next(), but
otherwise it seems I have to cast to
an Array to retrieve an item at a
specific index?
What are the appropriate ways of
retrieving data from a set? (other
than using an iterator)
You should also familiarise yourself with the SortedSet inte...
Accessing Object Memory Address
...you can just call PyFoo_Check to make sure it really is a Foo object, then cast with (PyFoo *)p. So, if you're writing a C extension, the id is exactly what you need.
What if you're writing pure Python code? You can call the exact same functions with pythonapi from ctypes.
Finally, a few of the ...

No i dont, i use the idea behind the answer, to cast the functional to tell the compile what type it is and it worked.

Is it safe to delete a void pointer?
...e of the original pointer. The only way to restore an object pointer is to cast the void pointer back to an object pointer (which requires the author to know what the pointer means). void itself is an incomplete type and thus never the type of an object, and a void pointer can never be used to ident...
How does lombok work?
...essor). JSR 269 does not let you modify existing source code, but when you cast an Element to the underlying AST node, you can actually modify the AST (which is what project Lombok does).
So Lombok is a huge hack that will only run compile on a Sun VM (afaik). It's a great piece of software, but it...

@RodrigoSalazar std::move is just a fancy cast from a lvalue reference (&) to an rvalue reference (&&). Extraneous usage of std::move on an rvalue reference will simply be a noop

How do I use itertools.groupby()?
...dged" in this way. Since all of the itertools are iterators, they must be cast to a builtin (list(), tuple()) or consumed in a loop/comprehension to display the contents. These are redundancies the author likely excluded to conserve space.

How to see if an object is an array without using reflection?
...e value of the RelationalExpression is not null and the reference could be cast to the ReferenceType without raising a ClassCastException. Otherwise the result is false.
That means you can do something like this:
Object o = new int[] { 1,2 };
System.out.println(o instanceof int[]); // prints "true"...
Which are more performant, CTE or temporary tables?
...Y, B INT , F CHAR(8000) NULL);
INSERT INTO T(B)
SELECT TOP (1000000) 0 + CAST(NEWID() AS BINARY(4))
FROM master..spt_values v1,
master..spt_values v2;
Example 1
WITH CTE1 AS
(
SELECT A,
ABS(B) AS Abs_B,
F
FROM T
)
SELECT *
FROM CTE1
WHERE A = 780
