Online C++ compiler with input stream?
提问by Xorty
I kinda like codepad online editor (supports C++), but I'd like to use some scanfs which is not possible with codepad.
我有点喜欢codepad 在线编辑器（支持 C++），但我想使用一些scanfs，这在codepad中是不可能的。
Is there some online C++ compiler that supports input streams? Is that even possible?
是否有一些支持输入流的在线 C++ 编译器？这甚至可能吗？

Getting very pedantic, you could stuff your input inside the source file by playing this dirty trick:
变得非常迂腐，你可以通过玩这个肮脏的把戏来把你的输入塞进源文件中：
/* just skip the first two (!!!) lines when reading from t.cpp

423.927317911
520.43881927

*/ // end of fake input
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
std::ifstream ifs("t.cpp");
std::cout << ifs.rdbuf() << std::flush;
}

Rextesterhas an input box as well and has a more usable interface than ideonewhich I have always felt was very clunky.
Rextester也有一个输入框，并且有一个比ideone我一直觉得非常笨重的更有用的界面。
Coliruallows you to use multiple files, so you can create an file with your data and do something like this to input into your program:
Coliru允许您使用多个文件，因此您可以使用您的数据创建一个文件并执行以下操作以输入到您的程序中：
g++ -std=c++11 -W -Wall main.cpp && cat /Archive/{{id}}/main.cpp | a.out
Note, LWSalso has a nice interface and an input box but has been in read-onlymode for a while now and it is not clear it is coming back online anytime soon if at all.
请注意，它LWS还有一个不错的界面和一个输入框，但现在已经处于read-only模式中了一段时间，目前尚不清楚它是否会很快重新上线（如果有的话）。

You can try http://optimizedbits.com. There you can also compile your code by providing your own stream of multiple inputs.
你可以试试http://optimizedbits.com。在那里，您还可以通过提供您自己的多个输入流来编译您的代码。
For just one input stream, simply write the input. For multiple input test cases, follow:
对于只有一个输入流，只需编写输入。对于多输入测试用例，请遵循：
input1
<TESTCASE>
input2
<TESTCASE>
....
Regarding the possibility of input stream: See no body builds a compiler on their own. Everybody utilizes some standards like gcc in the back-end. All online compiler websites work around a architecture which involves the following flow(example:C++):
关于输入流的可能性：看到没有机构自己构建编译器。每个人都在后端使用一些标准，如 gcc。所有在线编译器网站都围绕涉及以下流程的架构工作（示例：C++）：
1) read_code_user
2) Save it as variablename.cpp
3) Use a queuing framework. Then execute g++ variablename.cpp. Further, various libraries are utilized which can pipe stdin, stdout and stderr.
