I've reinstalled Visual Studio 2010 Professional several times to try to get it to work. I had to uninstall Visual Studio 2012 Professional because it wasn't compiling something we did in class.

我已多次重新安装 Visual Studio 2010 Professional 以尝试使其正常工作。我不得不卸载 Visual Studio 2012 Professional，因为它没有编译我们在课堂上做的事情。

I completely uninstalled everything including SQL Server..

我完全卸载了包括 SQL Server 在内的所有内容。

I went to VC/include and the iostream header file is not there.

我去了 VC/include 并且 iostream 头文件不在那里。

#include <iostream>

int main () {

cout << "hello";

system ("PAUSE");
return 0;
}

This is all I'm trying to do because nothing else is working.

这就是我正在尝试做的所有事情，因为没有其他任何工作。

It's really driving me crazy because I need to get it working so that I can do my project!!!

这真的让我发疯，因为我需要让它工作，这样我才能完成我的项目！！！

Every time I do; new project => empty project => add an item to source =>.cpp

每次我这样做；新项目 => 空项目 => 将项目添加到源 =>.cpp

I'm running windows 8.

我正在运行 Windows 8。

It just says Error cannot open source file Also, error cout identifier is undefined....

它只是说错误无法打开源文件此外，错误 cout 标识符未定义....

I'm wondering if I should do a system restore? Or if I should just completely reinstall windows 8 from my recovery media?

我想知道我是否应该进行系统还原？或者我是否应该从我的恢复媒体完全重新安装 Windows 8？

One problem is that you did not include the namespace std.

一个问题是您没有包含 namespace std。

This is what your code should look like:

你的代码应该是这样的：

#include <iostream>
using namespace std;

int main (void) {
    cout << "hello" << endl;
    system("pause");
    return 0;
}

or you could have done something like this: std::cout << "Hello" << std::endl;

或者你可以做这样的事情： std::cout << "Hello" << std::endl;

This may be a problem because you did not set your environment to C++. This is how you do it:

这可能是一个问题，因为您没有将环境设置为 C++。这是你如何做到的：

1. Go to Tools> Import and Export settings. If you cannot find it, just search for it in Quick Search
2. Then go to reset all settings.
3. Then simply select "Visual C++"
4. Restart.

1. 转到工具>导入和导出设置。如果找不到，只需在快速搜索中搜索即可
2. 然后去重置所有设置。
3. 然后只需选择“Visual C++”
4. 重新开始。

That should do the trick. If it does not, you might consider re-installing Visual C++ itself. For VS 2012. If that does not work, then re-install the program.

这应该够了吧。如果没有，您可以考虑重新安装 Visual C++ 本身。对于VS 2012。如果这不起作用，则重新安装该程序。
