VS2012出现“cannot open source file "iostream"”

1、创建或打开一个控制台应用

2、点击“Property Manager”--->右击“Debug|Win32” ---->点击“Property”----->点击“VC++ Directories” --->Executable Directories 选择“Edit” ----> Uncheck the "Inherit from parent or project defaults" option--->Recheck it and click "Ok".
- Repeat this for the includes, library directories, etc. -Click on "Apply" and "Ok" - Rebuild the project and check if this worked.
