Execution speed test in c++

i have a c++ and java program which both work. I know what i need to do in java now but not c++. The program gets the work done, but how can i time it? All examples i seem to be getting to test the speed are unix specific. This is my program

Code:

#include "stdafx.h"
#include <set>
#include <iostream>

using namespace std;

class RInteger {
private:
        int i;
public:
        RInteger(int v) { i = v; }
        friend ostream& operator <<(ostream& o, const RInteger &ri);
        inline friend bool operator <(const RInteger a, const RInteger b);
};

ostream&
operator <<(ostream& o, const RInteger &ri)
{
        cout << ri.i;
        return o;
}

inline bool
operator <(const RInteger a, const RInteger b)
{
        return (b.i < a.i);
}

int main(int argc, char *argv[])
{
        set <RInteger> s;
        int i;
        int rand = 10;

        for (i = 0; i < 1000000; i++) {
                s.insert(RInteger(rand));
                rand = rand * 1103515245 + 12345;
        }
        set<RInteger>::const_iterator si;
        for (i = 0, si = s.begin(); si != s.end(); i++, si++)
                if (i % 100000 == 0)
                        cout << *si << '\n';
        return 0;
}

So somehow i need to print out the starting time, and the ending time of this program. How would i add this to my program which would work? (using windows vista, visual c++ 2008).
cheers

You could use standard C functions in time.h like time() or clock(), but they probably aren't fast enough for your purposes.

In that case, I will suggest this solution. It's accurate to a few milliseconds, but it's Windows-specific. Displaying Function Run Time
