Question

I’ve used

#include<stdlib>
#include<time>
using namespace std;
srand((unsigned)time(0));
int n=(rand()>>8)%4;

but what other random functions are there, or what other function could be used as random number generators?

EDIT: I don’t really have a particular reason for asking this question, I just wanted to know if C++ had any other random functions.

Answer 1

The rand() and srand() functions are all the C++ Standard specifies. And if it comes to writing your own, be aware of what John von Neumann said:

“Anyone who considers arithmetical
methods of producing random digits is
of course in a state of sin”
