inline

usually if we put an implementation of a non-virtual member function in the header file that function would be inlined. how about if we put the implementation of a virtual member function in the header file? I guess it would be the same as putting it in the cpp file because inlining and polymorphism do not work together. Am I right on this? Putting the implementation of a method in the header file doesn't make it inline. Putting it in the class declaration does. I'll assume that's what you meant from now on. What is important here is that declaring a function inline is only an information to

题意：给一张无向图，并不断加边 \((u,v)\) ，并询问 \(u,v\) 是否位于同一个双联通分量里，若位于同一双联通分量，输出这个双联通分量的 \(size\) 使用并查集+LCT维护。 有两套并查集： s1 是用来维护每个点归属哪一个强连通分量，每个点的祖先是这个强连通分量的代表节点，同时代表节点存储这个强连通分量的 \(size\) ； s2 是用来维护原始图的联通性的。 注意加边时 \((u,v)\) ，我们都是对两个点所在联通分量的代表节点进行操作。 我们加边 \((u,v)\) 时，首先若两个点所在的联通分量的代表节点本来不连通，那直接加边（指同时修改 s2 和 LCT）即可。 若原来两个点所在的联通分量的代表节点联通，那么我们 split(u,v) ，将这条链（当然链上的点可能是一个联通分量）的所有点缩成一个点，我们把所有遍历到的点的 s1 都指向 \(u\) ，使 \(u\) 作为新联通分量的代表节点。 #include<bits/stdc++.h> #define R register int using namespace std; namespace Luitaryi { inline int g() { R x=0,f=1; register char s; while(!isdigit(s=getchar())) f=s=='-'?-1:f; do x

A couple of questions on C# Does C# support runtime inlining? Does JIT's optimizate before or during the execution of the code? Can a virtual function be inlined? C# the language doesn't do inlining, but the .NET CLR JIT compiler can. Virtuals might be inline-able in a sealed class, but I'm not sure about non-sealed classes. I would assume not. JIT optimizes before the execution of the code, when a function is first called. Because before the JIT goes to work, you don't have any code to execute. :P JIT happens only once on the first call to a function, not on every call to the function. Note

This question is very much related to: A) How to separate CUDA code into multiple files B) Link error LNK2005 when trying to compile several CUDA files together Following advice from here: https://meta.stackexchange.com/questions/42343/same-question-but-not-quite and here https://meta.stackexchange.com/questions/8910/asking-a-similar-but-not-the-same-question I am asking a very similar question but I want to be absolutely clear about where is the difference between my question and the questions linked above. I was getting the linker errors from the title when including a header file, which

I have a problem, may be dumb. The thing is, I am unable to inline a constructor in a class. Consider I have a class called Foo. If I write the implementation of Foo something like this: class Foo { int p; public: Foo() { p = 1; } }; or even like this: class Foo { int p; public: Foo(); }; inline Foo::Foo() { p = 1; } The program won't compile. I use the class using the standard method: Foo obj; Now when I run g++ main.cpp foo.cpp, I get: /tmp/ccyVtxvp.o: In function `main': main.cpp:(.text+0x17): undefined reference to `Foo::Foo()' collect2: ld returned 1 exit status At the same time, when I

Inline Temp 概述 一个临时变量，只被一个简单表达式赋值一次，而它妨碍了其它重构手法。 动机（Motivation） Inline Temp多半是作为Replace Temp with Query的一部分来使用。惟一单独使用Inline Temp的情况是：你发现某个临时变量被赋予某个函数调用的返回值。一般来说，这样的临时变量不会有任何危害，你可以放心地把它留在那儿。但如果这个临时变量妨碍了其它重构手法---例如Extract Method，就应该将它inline化。 作法（Mechanics） 1、如果这个临时变量并未被声明为final，那就将它声明为final，然后编译。 这可以检查该临时变量是否真的只被赋值一次。 2、找到该临时变量的所有引用点，将它们替换为为临时变量赋值的语名中的等号右侧表达式。 3、每次修改后，编译并测试。 4、修改完所有引用点之后，删除该临时变量的声明式和赋值语名。 public class InlineTemp { //before inline-temp public double GetUserSalary(String name) { double salary = userSalary(name); return salary ; } //after inline-temp public double

I have some icons inside divs and needed to lay them out with a left-to-right structure instead of the default top-to-bottom layout that seems to come with divs. It's probably not news to most people who know CSS but I figured out (with a little help ) that I could cause the divs to layout left-to-right using either: float: left/right or display:inline. My question is - is one preferable over the other ? <div id="icons"> <div id="divtxt" class="divicon"> <img src="/icons/text.png" id="icontxt" class="icon"/> </div> <div id="divpdf" class="divicon"> <img src="/icons/pdf.png" id="icondoc" class=
