srand()                  Set Random Starting Point
 
 #include   <stdlib.h>                   Required for declarations only
 
 void       srand(seed);
 unsigned   seed;                        Seed for random-number generation
 
    srand() provides the starting point for the series of pseudorandom
    integers generated by the function rand().  The generator is
    reinitialized by calling srand() with 1 as the 'seed' argument; any
    other value of 'seed' sets the generator to a random starting point.
 
    Returns:    There is no return value.
 
  -------------------------------- Example ---------------------------------
 
    The following statements generate 10 random numbers.
 
           #include <stdlib.h>
           #include <stdio.h>
 
           int i, seed = 20;
           int num;
 
           main()
           {
                srand(seed);
                printf("     RANDOM NUMBERS \n");
                for (i = 1; i <= 10; i++)
                    printf("index: %d,  random number: %d \n",i,rand());
            }
