Do you want the C++Builder project as well, or is this enough?

#include <windows.h>
#include <iostream>
int main(int argc, char* argv[])
{
LARGE_INTEGER Start, End, Temp;
    QueryPerformanceCounter(&Start);
    for (unsigned int i = 0; i < 1000000; ++i)
    {
        QueryPerformanceCounter(&Temp);
    }
    QueryPerformanceCounter(&End);

LARGE_INTEGER Frequency;
    QueryPerformanceFrequency(&Frequency);

double Time = (static_cast<double>(End.QuadPart) - Start.QuadPart) / Frequency.QuadPart;
    std::cout << Time << std::endl;
    return 0;
}
