问题 (Related to a previous unanswered question I asked). I want to implement a function which can be called only with vectors of related classes as parameter. For eq if we have class A; class B: public A; class C: public A; class D then it should be possible to call function with vector<A*>,vector<B*> or vector <C*> but not vector <D*> Any suggestions 回答1: I guess you already tried to create a method like void doSomething(std::vector<A*>& things) { } and tried do pass std::vector<B*> bList = ...;

问题 I've been looking at the implementation and I don't understand why there is an offset. I assume it is important. I'm taking an Algorithms course taught by Sedgewick, and we're talking about Strings now. In lecture he briefly discussed the String implementation, but he doesn't go over why there is an offset (Note, if lectures were not online, I would definitely have asked). It seems when one makes a String that within the implementation, it is given an offset, and I can't seem to understand

问题 I am a C# programmer but I have to work with some VB.Net code and I came across a situation where I have two methods on an interface with the same name but different method parameters. When I attempt to implement this interface in a class, VB.Net requires explicitly declaring "Implements MethodName" after the method signature. Since both method names are identical, this is confusing the compiler. Is there a way to get around this sort of problem? I suspect this must be a common occurrence.

问题 Is a standard-conforming C++ implementation allowed to implement some behavior that is said to be implementation-defined in the standard in such way that it is different between different runs of the same compiled once program with the same input data? For example, is an implementation allowed to say "the behavior is this on weekends and that otherwise" and implement behavior according to such statement? 回答1: Of course, if the implementation documents when exactly the behavior changes with

问题 I'm not sure if its the right title but ill explain what i mean. I'm making more than one android application, but they have the same structure sliding menu , list view , about me , costume dialog with (copy,share,like) with some modifications in the styles (colors, backgrounds , fonts , menu strings ) my qustion is : is there any way to use the structure as library or implemntation or anu other way insted of coping the same codes in every projects ? 回答1: Basically what you want to do is to

I am looking for internal implementation of a random number generator in C/C++.Basically I am interested to know, what exactly happens when rand() is called. After all machine follows definite set of instructions, how can it be random! Edit: Want to know how can I implement one in C/C++. 回答1: They're pseudo-random number generators, not truly random ones. This is often a

问题 Iota is a ridiculously small "programming language" using only one combinator. I'm interested in understanding how it works, but it would be helpful to see the implementation in a language I'm familiar with. I found an implementation of the Iota programming language written in Scheme. I've been having a little trouble translating it to Haskell though. It's rather simple, but I'm relatively new to both Haskell and Scheme. How would you write an equivalent Iota implementation in Haskell? (let

问题 first off I should ask: Does anyone knows of a current implementation 128b UINT for Java? I need something to hold natural cardinal values. ie: A huge counter. I know of BigIntegers, which are slow and immutable. A 128b UINT makes sense ... I was thinking about implementing an OWORD, using a pair of primitive longs. Overflows would throw an Exception and not Wraparound. What example sourcecode/blogs should I look to for implementing the workings of this class? 回答1: I would use 32 bit integers
