Normally you could do:

#include <windows.h>
#include <shlwapi.h>
#include <iostream>
int main()
{
    DWORD Size;
    char Buffer[1024];
    AssocQueryString(0, ASSOCSTR_EXECUTABLE, ".htm", "Open", Buffer, &Size);
    std::cout << "Assoc: " << Buffer << std::endl;
}

But the default version of windows libraries and headerfiles
shipped with Digital Mars does not have shlwapi.h, so you
will need to do some tricks.

In some cases ShellExecute is the answer.

One that works with Digital Mars:

#include <cstdlib>
#include <string>
#include <windows.h>
#include <iostream>

typedef DECLSPEC_IMPORT HRESULT WINAPI (*AssocQueryStringType 
)(DWORD,DWORD,LPCSTR,LPCSTR,LPSTR,DWORD*);

int main()
{
    HMODULE Module = LoadLibrary("shlwapi.dll");
    AssocQueryStringType AssocQueryString = 
(AssocQueryStringType)GetProcAddress(Module, "AssocQueryStringA");
    if(AssocQueryString)
    {
       char Buffer[1024] = "";
       DWORD Size = sizeof(Buffer);
       AssocQueryString(0, 2, ".htm", "open", Buffer, &Size);
       std::cout << "Assoc: " << Buffer << std::endl;
    }
    else
    {
       std::cout << "No Such proc" << std::endl;
    }
}

You could use dl_call (from the STLSoft sub-project, WinSTL;
http://stlsoft.org/), for simpler syntax:

#include <winstl/dl/dl_call.hpp>
#include <winstl/error/error_desc.hpp>
#include <iostream>

int main()
{
    try
    {
        char    Buffer[1024]    =   "";
        DWORD   Size            =   sizeof(Buffer);
        HRESULT hr;

        hr = winstl::dl_call<HRESULT>("SHLWAPI.dll",
"stdcall:AssocQueryStringA", 0, 2, ".htm", "open", &Buffer[0], &Size);

        if(SUCCEEDED(hr))
        {
            std::cout << "Assoc: " << Buffer << std::endl;
        }
        else
        {
            std::cerr << "Failed: " << winstl::error_desc(hr) << std::endl;
        }
    }
    catch(winstl::windows_exception& x)
    {
        std::cerr << "Error: " << x.what() << std::endl;
    }

    return 0;
}
