How to transfer char [] to allocator < char > by cPP

Let yourself design a string-like type that requires a constructor that accepts parameters of type char*

class MyString {

MyString();
MyString(char*);    
allocator<char> alloc_char;

};

MyString::MyString ()
{
}
MyString::MyString (char* tc) {/ / pass a parameter of type char []. Class purpose: support a

                                //char[] string
int num = sizeof(tc);            //
vector<char> trans(tc,tc+num);    //allocator[]            
                                //vector[] 
//allocator<char> alloc_char;        //
auto const  p = alloc_char.allocate(num);    //
auto q = uninitialized_copy(trans.begin(),trans.end(),p);        
//auto q=p; 
//q


/*
{        //
}*/
while (q != p)        //q
    alloc_char.destroy(--q);
alloc_char.deallocate(p, num);
//auto tc_begin = tc.begin();

}

int main ()
{

NULL;


return 0;

}

I had hoped to transfer the char* to the Allocator [char] successfully before proceeding with other processes.?

actual error message:
error C 4996 "std::uninitialized_copy::_Unchecked_iterators::_Deprecate": Call to" std::uninitialized_copy" 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 CPP "Checked Iterators" (Line) 53

error location code (in the header file < memory >):
template < class _ InIt,

class _FwdIt> inline
_FwdIt uninitialized_copy(_InIt _First, _InIt _Last,
    _FwdIt _Dest)
{    // copy [_First, _Last) to raw [_Dest, ...)
_DEPRECATE_UNCHECKED(uninitialized_copy, _Dest);
_DEBUG_RANGE(_First, _Last);
const auto _UFirst = _Unchecked(_First);

return (_Rechecked(_Dest,
    _Uninitialized_copy_unchecked(_UFirst, _ULast, _UDest, _Ptr_copy_cat(_UFirst, _UDest))));
}

my Xiaobai doesn"t quite understand. It should be the initialization problem of allocator. Replace that line with auto qroomp; and it will work properly.
