如何解决在 Visual Studio-2013 for C++ 中输入或编译后输出控制台消失的问题？

Question

我是 C++ 编码新手，在 Visual studio 环境中。我正在编译查找一个数字的 sqrt 的简单代码，甚至运行但是在将数字作为输入后控制台消失了，我留下了调试消息和程序的最终消息以退出代码 0 终止。基本上没有显示输出。

#include <cmath>
#include <iostream>

int main()
{
    double x{ 0.0 };

    std::cout << "Enter x-";
    std::cin >> x;

    if (x >= 0)
        std::cout << "\nSqrt(" << x << ") = " << std::sqrt(x) << std::endl;
    else
        std::cout << "\nWrong Value - cannot compute sqrt\n";
}

代码看起来不错，运行在线编译器上。我已经尝试从 Linker->System->Sub-system->Console (/SUBSYSTEM:CONSOLE) 检查 'console' 选项。但是没有任何效果。

似乎还生成了某些调试消息，其中一些我在下面显示 -

......

我尝试检查工具->调试->符号->Microsoft 符号服务器。找到了一些 PDF 文件，有些则没有。我想找到这个问题的根源，基本上让我的程序按照其编码的方式运行，输出控制台接受输入并显示结果。

可以在代码末尾临时加一行：

system("pause");

别忘了包括：#include <cstdlib>
