Visual Studio - 如何在非控制台应用程序中查看cout输出？ [英] Visual Studio - How can I see cout output in a non-console application?

问题描述

输出到调试窗口似乎相当冗长乏味。如果我正在写一个非控制台信息，在哪里可以找到 cout 输出？

It seems rather tedious to output to debug window. Where can I find cout output if I am writing a non-console information ?

Like：

double i = a / b;
cout << b << endl;//I want to check out whether b is zero. It seems the output cannot be found anywhere.

推荐答案

要将字符串输出到调试控制台， code> OutputDebugStringA 。请参见 http：// msdn。 microsoft.com/en-us/library/windows/desktop/aa363362%28v=vs.85%29.aspx

To output a string to the debug console, use OutputDebugStringA. See http://msdn.microsoft.com/en-us/library/windows/desktop/aa363362%28v=vs.85%29.aspx

要将变量值输出到调试控制台，使用 std :: ostringstream ，将字符串发送到 OutputDebugStringA 。

To output variable values to the debug console, using std::ostringstream, the send the string to OutputDebugStringA.

过多的输出语句将导致程序严重减慢。但是，它是一个很好的技巧，抓住调试器有问题，如实际的孩子成员在玩基本指针时。

Excessive output statements will cause the program to severly slow down. However, it is a good technique to catch things the debugger has a problem with, such as the actual child members when playing with base pointers.
