  I have defined function which returns table with 2 columns. Can I rename these columns so that resulting table would be like: Press name | Sum of pages ?

  int, char and bool usually have different sizes. Where intcharbool, I suppose. But does the RAM even support this? How is it built up? Can it take advantage of bool being only 1 byte and store it in a small "register"?

• Access specifier's and classes and objects?

  - by TimothyTech

  Alright, im trying to understand this, so a class is simply creating a template for an object. class Bow { int arrows; }; and an object is simply creating a specific item using the class template. Bow::Bow(arrows) { arrows = 20; } also another question, public specifiers are used to make data members avaible in objects and private specifiers are used to make data memebers only avaialble inside the class?

• simple interview question

  - by calvin

  Input integer array: a[8] = { a1, a2, a3, a4, b1, b2, b3, b4 } Output array: a[8] = { a1, b1, a2, b2, a3, b3, a4, b4 } Forget all corner cases, make sure your solution works for any int array of size 2n. You can use one or two temp variables for looping or anything, but you shouldn't use any temp arrays/stacks/queues etc to store entire array or part of array. I'm able to get answer in O(n*log n), but I'm looking for better solution.

• Android - Add other values to websettings settextsize

  - by user1681477

  In my application I am using a webview, and in order to increase/decrease text size, I am using WebSettings().setTextSize method, but, this method is limited to 5 predefined enum sizes only (SMALLEST, SMALLER, NORMAL, LARGER,LARGEST). I know I can use WebSettings().setTextZoom(int), but my application is available for API Level 8 and above, and this method was introduced in API Level 14... My question is: Is there any way to add other sizes to webSettings().setTextSize? maybe by extending textSize enum, or define other sizes?

• Can this statement ever evaluate to FALSE?

  - by BojanG

  I stumbled upon this while doing a review and the author is not available: int n = Convert.ToInt32(text); if (((n > 0) || (n < 0)) || (n == 0)) { return 1; } The code in general looks solid and it's hard for me to believe that the only purpose of this snippet is to confuse reviewers, but I don't see a way for this condition to fail. Am I missing something?

• What is the purpose of using a reference to a reference in C++?

  - by SilverSun

  In my adventures studying the boost libraries, I've come across function signatures that have parameters which are a reference to a reference to an object. Example: void function(int && i); What is the purpose/benefit of doing it this way rather than simply taking a reference to an object? I assume there is one if it's in boost.

  How can I write a recursive search that I avoid cycles. My class is this: class Component(var name: String, var number: Int, var subComponent: Set[Component]) Now I need a way to check whether a component is contained within its subcomponent or between subcomponent of its subcomponent and so on.Avoiding possible cycles caused by other Component.

  I have been using this "logic" in C++ and VB with success, but am tied up in Java... Simply put, public void DataProviderExample(String user, String pwd, String no_of_links, String link1, String link2, String link3) { for (int i=1;i<=no_of_links;i++) { String link = "link"+i; System.out.println(link); } Now, if the variables link1, link2 and link3 have a value of "X", "Y" and "Z" respectively, upon running this program, I get the following output - link1 link2 link3 What I want is - X Y Z Any ideas?
