How to count the number of set bits in a 32-bit integer?
...entation-defined for negative values. The argument needs to be changed (or cast) to unsigned, and since the code is 32-bit-specific, it should probably be using uint32_t.

How are virtual functions and vtable implemented?
...more constant table
&vtableFoo, // can dynamic_cast to Foo
(void(*)(Foo*)) destructBar, // must cast type to avoid errors
(int(*)(Foo*)) aBar
};
void constructBar(Bar* self) { // Bar::Bar()
self->base.vtable = &vtableBar; // point to Bar vtable
}

How could I convert data from string to long in c#
...er part of that number you must first convert it to a floating number then cast to long.
long l1 = (long)Convert.ToDouble("1100.25");
You can use Math class to round up the number as you like, or just truncate...

Understanding why Zipper is a Comonad
...viewed as a comonad just as well (in multiple ways), while a Zipper can be cast as a monad (also in many ways). The difference is in whether you are conceptually focused on "appending" data constructively to a state machine (that's what the Monad interface is about), or "extracting" state from it "d...
Would it be beneficial to begin using instancetype instead of id?
...eclare fileHandleWithStandardOutput as returning an instancetype. Then the cast or assignment isn't necessary.
(Note that on iOS, this example won't produce an error as only NSFileHandle provides a writeData: there. Other examples exist, such as length, which returns a CGFloat from UILayoutSupport ...
