How do I scale down numbers from rand()?

The following code outputs a random number each second:

int main ()
{
    srand(time(NULL)); // Seeds number generator with execution time.

    while (true)
    {
        int rawRand = rand();

        std::cout << rawRand << std::endl;

        sleep(1);
    }
}

How might I size these numbers down so they're always in the range of 0-100?
