error C4996: 'std::_Copy_impl': Function call with parameters that may be unsafe - this call relies on the caller to check that the passed values are correct. To disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to use Visual C++ 'Checked Iterators'

项目->project名称属性->c\c++ -> 预处理器 -> 预处理器定义 里添加
_SCL_SECURE_NO_WARNINGS 编译成功 ，
