A parameter is something you have to fill in when you call a function. What you put in it is the argument. 

Simply set: the argument goes into the parameter, an argument is the value of the parameter.

There is already a Wikipedia entry on the subject (see <a href="http://en.wikipedia.org/wiki/Parameter_(computer_science)" rel="noreferrer">Parameter</a>) that defines and distinguishes the terms parameter and argument. In short, a parameter is part of the function/procedure/method signature and an argument is the actual value supplied at run-time and/or call-site for the parameter. 

The Wikipedia article also states that the two terms are often used synonymously (especially when reasoning about code informally):

<blockquote>
 Although parameters are also commonly
 referred to as arguments, arguments
 are more properly thought of as the
 actual values or references assigned
 to the parameter variables when the
 subroutine is called at runtime.
</blockquote>

Given the following example function in C that adds two integers, <code>x</code> and <code>y</code> would be referred to as its parameters:

<pre><code>int add(int x, int y) {
 return x + y;
}
</code></pre>

At a call-site using <code>add</code>, such as the example shown below, 123 and 456 would be referred to as the arguments of the call.

<pre><code>int result = add(123, 456);
</code></pre>

Also, some language specifications (or formal documentation) choose to use parameter or argument exclusively and use adjectives like formal and actual instead to disambiguate between the two cases. For example, C/C++ documentation often refers to function parameters as formal arguments and function call arguments as actual arguments. For an example, see “<a href="http://msdn.microsoft.com/en-us/library/f81cdka5.aspx" rel="noreferrer">Formal and Actual Arguments</a>” in the <a href="http://msdn.microsoft.com/en-us/library/3bstk3k5.aspx" rel="noreferrer">Visual C++ Language Reference</a>.

blocks|key|181173|text|这些术语在某种程度上可以互换。其他答案中描述的区别用函数正文中使用的名称的形式参数和在调用站点提供的值的参数(形式参数和参数也是常见的)来更恰当地表示。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|181174|还请注意，在数学中，参数这个术语更常见，参数通常意味着完全不同的东西(尽管参数方程中的参数本质上是两个或多个函数的参数)。|181175|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

The terms are somewhat interchangeable. The distinction described in other answers is more properly expressed with the terms formal parameter for the name used inside the body of the function and parameter for the value supplied at the call site (formal argument and argument are also common).

Also note that, in mathematics, the term argument is far more common and parameter usually means something quite different (though the parameter in a parametric equation is essentially the argument to two or more functions).

They both dont have much difference in usage in C, both the terms are used
in practice.
 Mostly arguments are often used with functions. The value passed with the function calling statement is called the argument, And the parameter would be the variable which copies the value in the function definition (called as formal parameter). 

<pre><code>int main ()
{
 /* local variable definition */
 int a = 100;
 int b = 200;
 int ret;

 /* calling a function to get max value */
 ret = max(a, b);

 printf( "Max value is : %d\n", ret );

 return 0;
}

/* function returning the max between two numbers */
int max(int num1, int num2) 
{
 /* local variable declaration */
 int result;

 if (num1 &gt; num2)
 result = num1;
 else
 result = num2;

 return result; 
}
</code></pre>

In the above code <code>num1</code> and <code>num2</code> are formal parameters and <code>a</code> and <code>b</code> are actual arguments.

In editing, I'm often put off at how people forget: structure languages are based on natural languages. 

<h2>In English</h2>

A "parameter" is a placeholder. They set the response format, in spoken language. By definition, it's party to the call, limiting the response.

An "argument" is a position that is being considered. You argue your opinion: you consider an argument. 

<h2>Main difference</h2>

The thematic role of an argument is agent. The thematic role of parameter is recipient. 

<h2>Interactions</h2>

Think of the argument as the male part, making the parameter the female part. The argument goes into the parameter. 

<h2>Usage</h2>

A parameter is usually used in definitions. An argument is usually used in invocations. 

<h2>Questions</h2>

Finish the sentence to make it less dissonant.

(A) Speaking of a definition:

<ol>
<li>What argument will be used []?</li>
<li>What [] will this parameter []?</li>
</ol>

(B) Speaking of an invocation:

<ol>
<li>What parameter will you use, []?</li>
<li>What [] will be [] this parameter? </li>
</ol>

<h2>Answers</h2>

(A) 

<ol>
<li>on/in/against/with this parameter</li>
<li>argument(s) ... take </li>
</ol>

(B) 

<ol>
<li>and what are some example arguments</li>
<li>argument(s) ... used on/in/against/with</li>
</ol>

<h2>Overlaps</h2>

As you can imagine, after answering: in spoken language, these words will sometimes produce identical responses! 

So, as a rule: 

<ul>
<li>Usually if someone wants parameter information, they want to know more about the type, the variable name, etc. They may become confused if you only give example arguments. 

<ul>
<li>Usually if someone wants argument information, they want to know what value you passed to a function or its parameter(s).</li>
</ul></li>
</ul>

<h1>Simple Explanations without code</h1>

A "parameter" is a very general, broad thing, but an "argument: is a very specific, concrete thing. This is best illustrated via everyday examples:

<h3>Example 1: Vending Machines - Money is the parameter, $2.00 is the argument</h3>

Most machines take an input and return an output. For example a vending machine takes as an input: money, and returns: fizzy drinks as the output. In that particular case, it accepts as a parameter: money. 

What then is the argument? Well if I put $2.00 into the machine, then the argument is: $2.00 - it is the very specific input used.

<h3>Example 2: Cars - Petrol is the parameter</h3>

Let's consider a car: they accept petrol (unleaded gasoline) as an input. It can be said that these machines accept parameters of type: petrol. The argument would be the exact and concrete input I put into my car. e.g. In my case, the argument would be: 40 litres of unleaded petrol/gasoline.

<h3>Example 3 - Elaboration on Arguments</h3>

An argument is a particular and specific example of an input. Suppose my machine takes a person as an input and turns them into someone who isn't a liar.

What then is an argument? The argument will be the particular person who is actually put into the machine. e.g. if Colin Powell is put into the machine then the argument would be Colin Powell. 

So the parameter would be a person as an abstract concept, but the argument would always be a particular person with a particular name who is put into the machine. The argument is specific and concrete.

That's the difference. Simple.

<h3>Confused?</h3>

Post a comment and I'll fix up the explanation.

blocks|key|1180551|text|Oracle的Java教程定义了这种区别：“参数是指方法声明中的变量列表。参数是在调用方法时传入的实际值。在调用方法时，所使用的参数必须按类型和顺序匹配声明的参数。”|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1180552|参数和参数的更详细讨论：https://docs.oracle.com/javase/tutorial/java/javaOO/arguments.html|offset|length|1180553|entityMap|0|LINK|mutability|MUTABLE|url|https://docs.oracle.com/javase/tutorial/java/javaOO/arguments.html^0|0|C|1U|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

Oracle's Java tutorials define this distinction thusly:
"Parameters refers to the list of variables in a method declaration. Arguments are the actual values that are passed in when the method is invoked. When you invoke a method, the arguments used must match the declaration's parameters in type and order."

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

<code>data-type name of the method (data-type variable-name)</code>

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.

blocks|key|853326|text|参数是function.Hence接收到的变量，它们在函数declaration.They中是可见的，包含变量名及其数据类型。参数是传递给另一个函数的实际值。这就是为什么我们可以在函数调用中看到它们。它们只是没有数据类型的值。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|853327|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Parameters are the variables received by a function.Hence they are visible in function declaration.They contain the variable name with their data type.
Arguments are actual values which are passed to another function. thats why we can see them in function call. They are just values without their datatype

Parameters and Arguments

<blockquote>
 All the different terms that have to do with parameters and arguments
 can be confusing. However, if you keep a few simple points in mind,
 you will be able to easily handle these terms.
 
 <ol>
 <li>The formal parameters for a function are listed in the function declaration and are used in the body of the function definition. A
 formal parameter (of any sort) is a kind of blank or placeholder that
 is filled in with something when the function is called.</li>
 <li>An argument is something that is used to fill in a formal parameter.
 When you write down a function call, the arguments are listed in
 parentheses after the function name. When the function call is
 executed, the arguments are plugged in for the formal parameters.</li>
 <li>The terms call-by-value and call-by-reference refer to the mechanism
 that is used in the plugging-in process. In the call-by-value method
 only the value of the argument is used. In this call-by-value
 mechanism, the formal parameter is a local variable that is
 initialized to the value of the corresponding argument. In the
 call-by-reference mechanism the argument is a variable and the
 entire variable is used. In the call- by-reference mechanism the
 argument variable is substituted for the formal parameter so that
 any change that is made to the formal parameter is actually made to
 the argument variable.</li>

Logically speaking,we're actually talking about the same thing.
But I think a simple metaphor would be helpful to solve this dilemma. 

If the metaphors can be called various connection point we can equate them to plug points on a wall.
In this case we can consider parameters and arguments as follows;

Parameters are the sockets of the plug-point which may take various different shapes. But only certain types of plugs fit them. 
Arguments will be the actual plugs that would be plugged into the plug points/sockets to activate certain equipments.

The formal parameters for a function are listed in the function declaration and are used in the body of the function definition. A formal parameter (of any sort) is a kind of blank or placeholder that is filled in with something when the function is called.

An argument is something that is used to fill in a formal parameter. When you write down a function call, the arguments are listed in parentheses after the function name. When the function call is executed, the arguments are plugged in for the formal parameters.

The terms call-by-value and call-by-reference refer to the mechanism that is used in the plugging-in process. In the call-by-value method only the value of the argument is used. In this call-by-value mechanism, the formal parameter is a local variable that is initialized to the value of the corresponding argument. In the call-by-reference mechanism the argument is a variable and the entire variable is used. In the call- by-reference mechanism the argument variable is substituted for the formal parameter so that any change that is made to the formal parameter is actually made to the argument variable.

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 )

It's explained perfectly in <a href="https://en.wikipedia.org/wiki/Parameter_(computer_programming)#Parameters_and_arguments" rel="nofollow noreferrer">Parameter (computer programming) - Wikipedia</a>

Loosely, a parameter is a type, and an argument is an instance.

In the function definition <code>f(x) = x*x</code> the variable <code>x</code> is a parameter; in the function call <code>f(2)</code> the value ``2 is the argument of the function. 

And <a href="https://en.wikipedia.org/wiki/Parameter" rel="nofollow noreferrer">Parameter - Wikipedia</a>

In <a href="https://en.wikipedia.org/wiki/Computer_programming" rel="nofollow noreferrer">computer programming</a>, two notions of <a href="https://en.wikipedia.org/wiki/Parameter_(computer_programming)" rel="nofollow noreferrer">parameter</a> are commonly used, and are referred to as <a href="https://en.wikipedia.org/wiki/Parameter_(computer_programming)#Parameters_and_arguments" rel="nofollow noreferrer">parameters and arguments</a>—or more formally as a formal parameter and an actual parameter.

For example, in the definition of a function such as

<code>y = f(x) = x + 2,</code>

x is the formal parameter (the parameter) of the defined function.

When the function is evaluated for a given value, as in

<code>f(3): or, y = f(3) = 3 + 2 = 5,</code>

is the actual parameter (the argument) for evaluation by the defined function; it is a given value (actual value) that is substituted for the formal parameter of the defined function. (In casual usage the terms parameter and argument might inadvertently be interchanged, and thereby used incorrectly.)

++++}|853607|现在您知道了，当我们在代码后面的某个地方调用对象上的构造函数/方法时，我们传递参数而不是parameters.Hence参数仅限于定义逻辑对象的位置，但是当实际创建物理对象时会使用参数。|853608|entityMap^0|26|7|0|0|C|7|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|10|8|@$9|11|A|12|B|C]]|D|@]|E|$]]|$1|M|3|N|5|H|7|13|8|@]|D|@]|E|$I|J]]|$1|O|3|P|5|6|7|14|8|@]|D|@]|E|$]]|$1|Q|3|R|5|H|7|15|8|@]|D|@]|E|$I|J]]|$1|S|3|T|5|6|7|16|8|@]|D|@]|E|$]]|$1|U|3|-4|5|6|7|17|8|@]|D|@]|E|$]]]|V|$]]

You need to get back to basics.Both constructors and methods have parameters and arguments.Many people even call constructors special kind of methods.This is how a method is declared parameters are used:

<pre><code> type name(parameters){
 //body of method
 }
</code></pre>

And this is how a constructor is declared parameters are used:

<pre><code>classname(parameters){
//body
}
</code></pre>

Now lets see an example code using which we calculate the volume of a cube:

<pre><code>public class cuboid {
 double width;
 double height;
 double depth;

 cuboid(double w,double h,double d) { 
 //Here w,h and d are parameters of constructor
 this.width=w;
 this.height=h;
 this.depth=d;
 }

 public double volume() {
 double v;
 v=width*height*depth;
 return v;
 }
 public static void main(String args[]){
 cuboid c1=new cuboid(10,20,30);
 //Here 10,20 and 30 are arguments of a constructor
 double vol;
 vol=c1.volume();
 System.out.println("Volume is:"+vol);

 }
 }
</code></pre>

So now you understand that when we call a constructor/method on an object at some place later in the code we pass arguments and not parameters.Hence parameters are limited to the place where the logical object is defined but arguments come into play when a physical object gets actually created.

The C Programming Language (2nd Edition) by Brian W. Kernighan and Dennis M. Ritchie (April 1988):
<blockquote>
Page 25, Section 1.7 - Functions
We will generally use parameter for a variable named in the parenthesized list in a function definition, and argument for the value used in the call of the function. The terms formal argument and actual argument are sometimes used for the same distinction.
</blockquote>
ISO/IEC 9899:2018 (C18):

DEPRECATED: actual parameter
expression in the comma-separated list bounded by the parentheses in a function call expression, or a sequence of preprocessing tokens in the comma-separated list bounded by the parentheses in a function-like macro invocation.

DEPRECATED: formal argument
object declared as part of a function declaration or definition that acquires a value on entry to the function, or an identifier from the comma-separated list bounded by the parentheses immediately following the macro name in a function-like macro definition.

 }

 public static void main(String args[]){
 Test test = new Test();
 String myName = &quot;James Bond&quot;;

The method definition of hello(String name) declares a String parameter called name.
In the main method we are calling the hello method by passing the argument myName.
So parameter is the placeholder where as argument is the actual value for a method.

I'm still not happy with all these answers. They all start talking about 'function declarations' and my monkey brain has already wandered off and started thinking about unicorns. That doesn't help me remember at all, it's just the definition.
I want something that I can immediately and forever hold in my head.
The <a href="https://stackoverflow.com/a/156778/327074">only answer here</a> that I quickly understand is:
<blockquote>
&quot;Arguments are actual values that are passed in&quot;.
</blockquote>
Arguments are easier to define and as long as you know what they are then you know parameters are the other.
The other way I can think of it is:
<ul>
<li>Arguments are the variables outside the function</li>
<li>Parameters are the variables inside the function</li>
</ul>
Simplified down to:
<blockquote>
Arguments outside, parameters inside
</blockquote>
If any one wants to disagree with me, you can leave your arguments outside and bring your parameters in ;)

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 I mean, but what's correct, and what's the history of the terms?

I'm a C# programmer, but I also wonder whether people use different terms in different languages.

For the record I'm self-taught without a background in Computer Science. (Please don't tell me to read <a href="http://www.amazon.co.uk/Code-Complete-Practical-Handbook-Construction/dp/0735619670/" rel="noreferrer">Code Complete</a> because I'm asking this for the benefit of other people who don't already have a copy of <a href="http://www.stevemcconnell.com/" rel="noreferrer">Steve McConnell</a>'s marvellous book.)

<h3>Summary</h3>

The general consensus seems to be that it's OK to use these terms interchangeably in a team environment. Except perhaps when you're defining the precise terminology; then you can also use "formal argument/parameter" and "actual argument/parameter" to disambiguate.

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

在口头上谈论方法时，我从来不确定是使用参数、参数还是其他什么。不管是哪种方式，其他人都知道我的意思，但什么是正确的，以及这些术语的历史呢？我是一个C#程序员，但我也想知道人们是否在不同的语言中使用不同的术语。说句公道话，我是自学的，没有计算机科学背景。(请不要让我读，因为我这样问是为了帮助那些还没有那本绝妙的书的人。)...
