Description

   srand initializes the random number generator rand() with a seed number.
   If srand() is never called, then the default is as if srand(1) was
   called.

Example 

   #include <stdio.h>
   #include <stdlib.h>

   int main()
   {
       int i;
       srand(9);
       for(i = 0;i < 20;i++)
           printf("i: %d rand(): %d\n",i,rand());
       return EXIT_SUCCESS;
   }
