How do I scale down numbers from rand()?

Question

The following code outputs a random number each second:

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

    while (true)

If you are using C++ and are concerned about good distribution you can use TR1 C++11 .

#include 

std::random_device rseed;
std::mt19937 rgen(rseed()); // mersenne_twister
std::uniform_int_distribution idist(0,100); // [0,100]

std::cout << idist(rgen) << std::endl;
