HelloWorld.cpp无法编译

Question

我试图学习用C ++编程，因为我现在几乎不懂语言。我下载了Visual Studio Express 2017并制作了一个非常简单的HelloWorld.cpp文件，但是我收到了如下所示的错误。

我已多次检查语法，但我没有在代码本身看到错误，这让我相信安装本身可能存在问题。但是，由于我对VSE很新，我甚至不知道从哪里开始解决这个问题。如果你能伸出援助之手，那就太好了。

错误消息：

[3/24/2018 6:49:30 PM Error] System.ArgumentNullException: Value cannot be null.

代码本身，如果你想确认它没有任何问题：

// HelloWorld.cpp

#include <iostream>

int main()
{
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

问题不在于你的代码。安装也应该没问题。我相信你没有正确设置你的C ++项目。请参阅this tutorial，其中阐述了如何在Visual Studio 2017中生成有效的C ++ Hello World项目的每个步骤。
