------ foo.cpp ------
#include <cstdlib>
#include <iostream>
using namespace std;
int main ()
{
  cout << rand() << endl;
  cout << rand() << endl;
  return 0;
}
---------------------


// g++ version 3.3.3 (cygwin special)

$ g++ foo.cpp

The program below generates the following output:
-----------
0
1481765933
-----------

First pseuso-random number is 0.

Is it by purpose?
