warning C4996: 'strncpy' was declared deprecated

error C2653: 'iso_base' : is not a class or namespace name

error C2664: 'std::ios_base::fmtflags std::ios_base::setf(std::ios_base::fmtflags)' : cannot convert parameter 1 from 'std::ios_base &(__cdecl *)(std::ios_base &)' to 'std::ios_base::fmtflags'

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
这个warming c4996 为什么老出现 我已经包含了 #include<cstring> 了，我用VC6的时候 没这个警告
然后是是'iso_base' : is not a class or namespace name
我对过代码了，没发现问题在哪里！

希望能得到以上三个错误的 原因！！
谢谢！！！
