What's the difference between an argument and a parameter?

Question

When verbally talking about methods, I\'m never sure whether to use the word argument or parameter or something else. Either way the other people know what

Answer 1

When we create the method (function) in Java, the method like this..

data-type name of the method (data-type variable-name)

In the parenthesis, these are the parameters, and when we call the method (function) we pass the value of this parameter, which are called the arguments.

Answer 2

Parameters are variables that are used to store the data that's passed into a function for the function to use. Arguments are the actual data that's passed into a function when it is invoked:

// x and y are parameters in this function declaration
function add(x, y) {
  // function body
  var sum = x + y;
  return sum; // return statement
}

// 1 and 2 are passed into the function as arguments
var sum = add(1, 2);

Answer 3

I thought it through and realized my previous answer was wrong. Here's a much better definition

{Imagine a carton of eggs: A pack of sausage links: And a maid } These represent elements of a Function needed for preparation called : (use any name: Lets say Cooking is the name of my function).

A Maid is a method .

( You must __call_ or ask this method to make breakfast)(The act of making breakfast is a Function called Cooking)_

Eggs and sausages are Parameters :

(because the number of eggs and the number of sausages you want to eat is __variable_ .)_

Your decision is an Argument :

It represents the __Value_ of the chosen number of eggs and/or sausages you are Cooking ._

{Mnemonic}

_" When you call the maid and ask her to make breakfast, she __argues_ with you about how many eggs and sausages you should eating. She's concerned about your cholesterol" __

( Arguments , then, are the values for the combination of Parameters you have declared and decided to pass to your Function )

Answer 4

A parameter is a variable in a method definition. When a method is called, the arguments are the data you pass into the method's parameters.

public void MyMethod(string myParam) { }

...

string myArg1 = "this is my argument";
myClass.MyMethod(myArg1);

Answer 5

Yes! Parameters and Arguments have different meanings, which can be easily explained as follows:

Function Parameters are the names listed in the function definition.

Function Arguments are the real values passed to (and received by) the function.

Answer 6

Generally speaking, the terms parameter and argument are used interchangeably to mean information that is passed into a function.

Yet, from a function's perspective:

• A parameter is the variable listed inside the parentheses in the function definition.
• An argument is the value that is sent to the function when it is called.
