Adding C++ headers is breaking Visual studio project compilation

Question

I've an existing VS2017 project (Not sure if it's pure C or a C/C++ project) which compiles perfectly fine till i add the below C++ header files.

<string>
<vector>
<iostream>

The moment i add any of the below C++ header files, it starts throwing the errors as below:

Not sure how do I fix this. How can i make my VS2017 project consume C++ headers also ?

我可以通过以下方式解决这个问题：将宏 _XKEYCHECK_H 添加到预处理器定义中。
