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

问题描述

当口头谈论方法时，我永远不确定是使用参数还是参数或其他词.无论哪种方式，其他人都知道我的意思，但什么是正确的，这些术语的历史是什么?

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?

我是一名 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.

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

为了记录，我是自学的，没有计算机科学背景.(请不要告诉我阅读代码完整 因为我是为了其他还没有史蒂夫·麦康奈尔 了不起的书.)

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.)

普遍的共识似乎是在团队环境中可以互换使用这些术语.除非您正在定义精确的术语；那么你也可以使用形式参数/参数"和实际参数/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

简单:

• PARAMETER → PLACEHOLDER(这意味着占位符属于函数命名并在函数体中使用)
• ARGUMENT → ACTUAL VALUE(这意味着函数调用传递的实际值)

• PARAMETER → PLACEHOLDER (This means a placeholder belongs to the function naming and be used in the function body)
• ARGUMENT → ACTUAL VALUE (This means an actual value which is passed by the function calling)
