Thread: Random Numbers :: C++

Hi.
I am experience recursive random number. It seems that only happens when rand() is in a loop.

For example:

--------------------------------------
srand(time(0));
int tempNUM = 0;

for (int i = 0; i < 1000; ++i)
{
tempNUM = 1 + rand() %9999999;
cout << tempNUM + 1;
}
--------------------------------------

In a program I am working on with a similar code to the one above, the program generates duplicates random numbers. It seems I have to *wait* one second clock until it generates a something new. Does that have something to do with time(0)?

I would like something that can generate a completely random number almost instantaneously even when it is in a for loop like the one above.

Thanks,

When I compile this program, it works fine. A different number every cout. I am using Dev-C++, though. What compiler are you using?

I am using VC++ 6.0.

Try using the function GetTickCount() in place of time(0). It should update pretty fast.
