Before you dive into the technical details of passing by reference, it’s helpful to take a closer look at the term itself by breaking it down into components:Pass means to provide an argument to a function. By reference means that the argument you’re passing to the function is a ...
Pass-by-value: 複製參數的值傳入,所以原參數內容不會被影響。 Pass-by-reference: 傳入參數的參考,會影響原參數內容。 還有少數程式語言使用以下兩種傳遞方式: Pass-by-name: 將傳入的參數視為變數名稱或是字串,概念類似 string evaluation。 Pass-by-value-result: 又稱 copy-in, copy-out,不直接傳入變數的...

This all means that you don’t pass the reference to self in this case because self is the parameter name for an implicitly passed argument that refers to the instance through which a method is being invoked. It gets inserted implicitly into the argument list. How to Define a Function: Use...
