What is the difference between a Parameter and an Argument in C#?

Well, I believe most people use these terms interchangeably. But what is the *formal* distinction between these two terms in C#?

Thanks for the help.

BCBThe *formal* difference is that an argument is a supplied value to a function or method. A parameter is a place holder for this value. This definition was depricated as of the C99 standard. as su i.e.

public class SomethingDoer
{
 public SomethingDoer()
 {
 String argument = "This is an argument.";
 DoSomething(argument);
 }
 public void DoSomething(String parameter)
 {
 //Do something here
 }
}

Paul - Thanks for clearing this up, but I have another question. If the definition was deprecated in the C99 standard, does that mean that post-C99 the terms parameter and argument are interchangeable?

Thanks.

From everyone and everywhere I've heard, yes. I may be young, 20, but I'm not a fan of colliding the terms. Fight for your right I guess. :)
