当口头谈论方法时,我从不确定是否应该使用参数或参数或其他词。不管怎样,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?
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。
声明一下,我是自学的,没有计算机科学的背景。(请不要让我去读《代码完成》,因为我这么做是为了让那些还没有史蒂夫·麦康奈尔这本了不起的书的人受益。)
总结
普遍的共识似乎是,在团队环境中可以互换使用这些术语。除非你在定义精确的术语;然后你也可以使用“正式参数/参数”和“实际参数/参数”来消除歧义。
参数和参数
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.
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.
