什么是参数和参数之间的区别？ [英] What's the difference between an argument and a parameter?

问题描述

在口头上谈论的方法，我无法知道是否使用这个词的参数或参数的或别的东西。无论哪种方式，其他的人知道我的意思，但什么是正确的，什么是术语的历史？

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?

我是一个C＃程序员，但我也想知道人们是否在不同的语言使用不同的术语。

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

有关记录我自学成才没有计算机科学的背景。 （请不要告诉我读 code完成因为我问这个的人谁不已经有史蒂夫·麦康奈尔的副本其他人的利益的奇妙的书。）

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.)

普遍的共识似乎是，它的确定在团队环境中交替使用这些术语。也许除了当你定义precise术语;那么你也可以使用正式的参数/参数和实际的参数/参数来消除歧义。

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.

推荐答案

一个参数是一个方法定义的变量。当一个方法被调用，参数是你传递给方法的参数的数据。

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);
