i just code a small program, it will tell you how many seconds will you
cost on using 10^9 times of additions.
the test result of my laptop(using the CPU of intel PM):
when my cpu running at 600MHz it takes 29.01s to finish it.
when it running at 1600MHz it takes about 5.22s to finsh it.
and i also find something strange. i use two kinds of compiler, one is VC6.0
another is GUN C++ to compile my addition code in C++. GUN C++ is about
3 times faster than the VC6.0. that is interesting.
the result above are using the program which compiled by GUN C++.
if anybody want to test it, just download my program from
www.i2mh.com/TestTime.rar
after you download it run the 'testall.bat'
and remember post your result from time.txt here

That is because you use the debug configuration,
it has no optimization by default.
Try the released configuration, which is maximized-speeded.
That would be much more faster, sometimes has better performance than GCC/G++

where can i find the 'released configuration' in vc6. thanks. btw: i hope
you can download my file and then test it. i want to know the result. thank you
very much!!
alec (AlecMonkeyKing) 于Fri Mar 26 21:01:15 2004提到：
I had set it to the maximized-speeded. but still the same. god we must use
the vc6.0 in the contest...

Where is your source code?
Dreamer (梦想的彼岸) 于Fri Mar 26 21:13:17 2004提到：
Really?
Give me your source code.I wanna have a try.

The code of my addition
#include <iostream>
using namespace std;
int main()
{
int i;
double k;
k=0;
for (i=0;i<1000000000;i++)
{
k=k+1;
}
cout << k;
return 0;
}
