In C++ sometimes in class definition public members are declared at first and privates later. But the variables or data members are normally private and used by the public methods. So, in this case variables are used but not even declared yet. Thus the code become difficult to understand. But I found renowned programmers, sites or books ...
I suspect that I'm missing something stupid, so feel free to blast me, but: I'm reading through Test Driven Development: By Example and one of the examples is bugging me. In chapter 3 (Equality for all), the author creates an equals function in the Dollar class to compare two Dollar objects: public boolean equals(Object object) { D...

This may be a daft question as I can see the security reason for it to happen the way it does... I have a licensing c# project, this has a class which has a method which generates my license keys.

I have a class that uses XML and reflection to return Objects to another class. Normally these objects are sub fields of an external object, but occasionally its something I want to generate on the fly. I've tried something like this but to no avail. I believe that's because JAVA won't allow you to access private methods for reflection....
There is a good generalized method for defining private and protected properties and methods in Javascript, here on the site. However, the current version of Prototype (1.6.0) doesn't have a built-in way to define them through its Class.create() syntax. I'm curious what the best practices are when developers want to define private and p...
Confession: I only use private and public visibility for my methods! I have a feeling this is a bad thing. But in Rails it just doesn't seem to come up as an issue. Does anyone have an example in Rails where it would be a big mistake not to use protected visibility? ...
I'm learning Java, and the book I'm reading has the following example on cloning. In clone(), my first instance is able to set buffer on the new object even though buffer is private. It seems like it should require the field to be protected for this to work. Why is this allowed? Does clone() have special privileges that allows it to acc...

When I am logged into WordPress (as the admin) and happen to also be browsing the Foo category page in a different tab in the same browser, I can see the private posts on the category page, with t...

In doxygen, I can create objective-c categories inside my implementation file to hide interfaces that shouldn't be accessed publicly. However, doxygen still documents the category as the members being "public". Even by adding the \protected or \private, this is still the case. Is there another method that I'm overlooking that would put...
I'm pretty sure there is no way, but i'm putting this out there for those expert beyond my knowledge. What i am looking to do is to somehow alter SELECT statements before they are executed, at the database level. For a seriously pared-down example, i'd like to do something like the following... when someone executes the following SQL ...

Hi all, In my continuing adventure with templates, I've templated my Container class not just on the ItemType it holds, but also on a Functor argument that determines how it should order the items. So far, so good. A little problem I've run into occurs when I want to copy the contents of one Container to another: If the two Container...

I want to have a class with a private static data member (a vector that contains all the characters a-z). In java or C#, I can just make a "static constructor" that will run before I make any instances of the class, and sets up the static data members of the class. It only gets run once (as the variables are read only and only need to be...

1) What's the policy for declaring a variable? Should you always use the keyword private, or is it OK to skip it? string MyVar1; vs. private string MyVar1; The only reason I see is that Microsoft one day can change the default access modifiers to public instead of private. Where does it say that private is optional? Any references...
