The words argument and parameter are often used
interchangeably although the C++ Standard makes a clear
distinction between the two.

An argument is an expression in the comma-separated list in
a function call or the operand of a throw-statement

A parameter is an object or reference that is declared in a
function declaration or definition (or in the catch clause
of an exception handler);


This example demonstrates the difference between a
parameter and an argument:

void func(int n, Object obj); //n and obj are parameters

static void main(String s[])
{
Object p = new String("hi");
func(5, p); //5 and p are arguments
}
