Unusual variable declaration in C++
// s isn't declared before
std::string(s);
s = "Hellow world";
It compiles and works as if s was declared as usual at least on msvc and gcc (C++14).

What is it called in .NET when a variable of a type is declared, but isn't actually instantiated?
such as:
int i;
or
public delegate void MyAwesomeDelegate(int i);
We have the word instantiate to mean we actually created an object. But what about when we have just declared variable of a type and it's just null?
