Till now i was using the rand() / (RAND_MAX / X); style that the others
suggested but as i thought it for a while i discovered that with this type
the possibility of all numbers is not the same (the largest number is very
seldom to occur). So my new implementation is:
// Assuming C++
#include <iostream>
#include <cstdlib>
#include <ctime>
int main()
{
using namespace std;
srand(time(0)); // With this we feed srand() with a different seed every
time.
while(true)
{
// suppose we want a value between 0-X
const int X=2;
int number=rand() / (RAND_MAX / (X+1));
if(number==X+1)
continue;
cout<<number<<' ';
}
}
