Visual Studio Code – Can't call function from .dll created in C++

I’m able to call function from DLL created in C (.c file), but i can’t do it from DLL created in C++ (.cpp file). I want to find out why it doesn’t work in .cpp file.

I’m trying to call function printword() from a simple DLL, created with Visual Studio 2022:

// FILE: dllmain.cpp

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
        break;
    }
    return TRUE;
}


__declspec(dllexport) void printword() {
    std::cout << "word" << std::endl;    //with printf() doesn't work too
}

And when i call function the way like this:

int main() {

    HMODULE dll;
    if ((dll = LoadLibrary(L"D:\Visual Studio projects\Dll1\x64\Debug\Dll1.dll")) == NULL) {
        return GetLastError();
    }

    FARPROC func;
    if ((func = GetProcAddress(dll, "printword")) == NULL) {
        return GetLastError();
    }

    func();

    return 0;
}

GetProcAddress throws error ERROR_PROC_NOT_FOUND

But if i create DLL in file with .c suffix printword() function calls correctly (with same code above):

// FILE: dllmain.c

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
        break;
    }
    return TRUE;
}


__declspec(dllexport) void printword() {
    printf("wordn");
}
