C dynamically growing array
...d to initialize an array, an expression that has type ''array of type'' is converted to an expression with type ''pointer to type'' that points to the initial element of the array object and is not an lvalue. If the array object has register storage class, the behavior is undefined." The same is tru...
I want to get the type of a variable at runtime
...y is that you want to reify the type of the variable. That is, you want to convert the type into a value, so you can store it, pass it around, etc. This involves reflection, and you'll be using either ClassTag or a TypeTag. For example:
val x: Any = 5
import scala.reflect.ClassTag
def f[T](v: T)(im...
initializer_list and move semantics
...zer_list.
In this example code, I used a set of small helper functions to convert the variadic arguments into a vector, to make it similar to the original code. But of course you can write a recursive function with variadic templates directly instead.

What is the fastest/most efficient way to find the highest set bit (msb) in an integer in C?
...ack a leading-zero counting instruction, but some of those can efficiently convert integers to double. Type-punning an FP bit pattern back to integer can be slow, though (e.g. on PowerPC it requires a store/reload and usually causes a load-hit-store stall).
This algorithm could potentially be usef...
How does Java handle integer underflows and overflows and how would you check for it?
