参数和参数有什么区别？(What's the difference between an argument and a parameter?)

在口头谈论方法时，我永远不会确定是使用单词参数还是其他参数 。 无论哪种方式，其他人都知道我的意思，但是什么是正确的，这些术语的历史是什么？

我是C＃程序员，但我也想知道人们是否使用不同语言的不同术语。

为了纪录我自学，没有计算机科学的背景。 （请不要告诉我阅读代码完成，因为我问这个是为了没有Steve McConnell的奇妙书的其他人的利益。）

概要

普遍的共识似乎是可以在团队环境中互换使用这些术语。 除了定义准确的术语之外， 那么你也可以使用“ 正式参数/参数”和“ 实际参数/参数”来消除歧义。

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 Code Complete because I'm asking this for the benefit of other people who don't already have a copy of Steve McConnell's marvellous book.)

Summary

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.

最满意答案

参数是方法定义中的变量。 当调用一个方法时，参数是传递给方法参数的数据。

public void MyMethod(string myParam) { } ... string myArg1 = "this is my argument"; myClass.MyMethod(myArg1);

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);
