Argument-passing may refer to two different things: (1) the process of providing a program being started with some initial pieces of information (the arguments) on its command line; (2) the process of providing the initial values (the arguments) for the parameters of a function when it is called.

Why is all data that is passed to a function "explicitly passed"?
Data is passed to a function "explicitly" whereas a method is "implicitly passed" to the object for which it was called.
Please could you explain the difference between these two ways of passing data? An example in java or c# would help.
