Code:
#include <windows.h>
#include <stdio.h>

typedef BOOL (WINAPI *LPFN_ISWOW64PROCESS) (HANDLE, PBOOL);

LPFN_ISWOW64PROCESS fnIsWow64Process;

BOOL IsWow64()
{
    BOOL bIsWow64 = FALSE;

    fnIsWow64Process = (LPFN_ISWOW64PROCESS) GetProcAddress(
        GetModuleHandle(TEXT("kernel32")),"IsWow64Process");
 
    if (NULL != fnIsWow64Process)
    {
        if (!fnIsWow64Process(GetCurrentProcess(),&bIsWow64))
        {
            // handle error
        }
    }
    return bIsWow64;
}

void main()
{
    if(IsWow64())
        printf("Running on WOW64\n");
    else printf("Running on 32-bit Windows\n");
}
