If you catch the (...) exception, where was it thrown?

IUn that case, you cannot even legally test p!=0 (it is likely randomly initialized, anyway, and the compiler might generate code that causes an access violation at runtime).

EXP obj;
printf("obj.c1: 0x%p \nobj.c2: 0x%p \nobj.i1: 0x%p \n", &obj.c1, &obj.c2, &obj.i1);

#include <fstream>
wchar_t file_name[] = L"hello.txt"; // ... Your file name source.
// std::fstream f(file_name, std::ios::in | std::ios::out);
std::wfstream f(file_name, std::ios::in | std::ios::out);

But an existing file with Byte-order Mark (Ex: FFFE), will not open with the above code.

std::wifstream file(file_name, std::ios::in | std::ios::binary);
