The compiler will normally issue a warning if the reference is incorrect (e.g. a reference to a different parameter than the last one, or a reference to a wholly different object), but will not prevent compilation from completing normally. va_arg takes two arguments, a va_list object (previously initialised) and a type descriptor. It expands to ...
Rest parameters are similar to Javascript's arguments object, which is an array-like object that contains all of the parameters (named and unnamed) in the current function call. Unlike arguments , however, rest parameters are true Array objects, so methods such as .slice() and .sort() can be used on them directly.
A sample UML class and sequence diagram for the observer design pattern. [6] In this UML class diagram, the Subject class does not update the state of dependent objects directly. Instead, Subject refers to the Observer interface (update()) for updating state, which makes the Subject independent of how the state of dependent objects is updated.

In case of call by value, what is passed to the function is the value of the argument – for example, f(2) and a = 2; f(a) are equivalent calls – while in call by reference, with a variable as argument, what is passed is a reference to that variable - even though the syntax for the function call could stay the same. [5]
For example, we can use subscripts to denote the arguments with respect to which partial derivatives are taken. [ 2 ] The use of the term "argument" in this sense developed from astronomy , which historically used tables to determine the spatial positions of planets from their positions in the sky ( ephemerides ).
Point of reference is the intentional use of one thing to indicate something else, and may refer to: Reference point (disambiguation), general usage;
A function call using named parameters differs from a regular function call in that the arguments are passed by associating each one with a parameter name, instead of providing an ordered list of arguments. For example, consider this Java or C# method call that doesn't use named parameters:
