Random Number

Expand Post »

Hey, I was just wondering how to get a variable assigned a random number within a certain range. I tried the rand, but I seem to get the same set of numbers everytime I run the code...

I did some research on random numbers in C++ and understand the whole pourpose of seeding random generation, but couldn't find anywhere that just gives me an example on how to do it. Does anyone know a website that could show me what to do? Or even show me here?

Thanks everyone,
-Matt

Re: Random Number

srand() seeds the random number generator, you should call srand() one time only and near the top of main(). Most of us use the time() function as the paramter to srand()

C++ Syntax (Toggle Plain Text)
int main()
{
   srand(time(0));
}
int main()
{
   srand(time(0));
}

Re: Random Number

Thank you, it worked good. Now I actually get different "random" numbers when the program runs each time.
