如何在Visual Studio 2015中显示标准输出？

[英]How to display standard output in Visual Studio 2015?

原文 2016-01-13 19:01:34 6 1 c++/ visual-studio/ visual-studio-2015

Most IDE's I've seen (NetBeans, QtCreator, XCode, CodeBlocks, Eclipse) provide an out-of-the-box method to view standard output either in one of its embedded window or external console or in a log BUT Visual Studio. 我见过的大多数IDE（NetBeans，QtCreator，XCode，CodeBlocks，Eclipse）提供了一种开箱即用的方法，可以在其嵌入式窗口或外部控制台之一或日志中查看标准输出但是Visual Studio。

I really don't want to allocate a separate console as it is suggested at THIS question. 我真的不想按照这个问题的建议分配一个单独的控制台 。 I'd also prefer not to redirect it to a file as it is suggested at THIS question (output file is not created with the suggested console command ( 2>output.txt )). 我也不想将它重定向到文件，因为这个问题是建议的（输出文件不是用建议的控制台命令创建的（ 2>output.txt ））。 Please don't give answers that modify the codebase like using OutputDebugString . 请不要像使用OutputDebugString那样给出修改代码库的答案 。

If displaying standard output inside VS this way is not possible, a working solution of the other two alternatives would still be welcomed, namely using external console (which I tried using without seeing the output in it) or a log file. 如果以这种方式在VS内部显示标准输出是不可能的，那么其他两个备选方案的工作解决方案仍然会受到欢迎，即使用外部控制台（我尝试使用它而不看其中的输出）或日志文件。

If it is only for debugging purposes, you might find Debug Breakpoints/Tracepoint actions helpful. 如果它仅用于调试目的，您可能会发现Debug Breakpoints / Tracepoint操作很有帮助。 They enable to log custom strings with expressions (ie variables) to the visual studio console. 它们可以将带有表达式（即变量）的自定义字符串记录到visual studio控制台。

For a non-console windows application, by default (ie without changing your codebase, as you are requesting) all output to stdout is lost.. 对于非控制台窗口应用程序，默认情况下（即，无需更改代码库，因为您要求）所有输出到stdout都会丢失。
