Puzzle R1

Print N random integers, one per line

[E-2] Write a main() program that prints N random integers one per line. Write the integers to standard output. On a Windows machine, write the integers to the DOS window. Here is the output of one run of the program:

  4068
   213
 12761
  8758
 23056
  7717
 15274
 24508
  4056
 13304

Copy-and-paste the following program into a source file and finish it.

/* Puzzle R01 -- print N random integers */

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

int main(int argc, char *argv[])
{
  int j;
  int limit = 25;            /* Print this many random integers */
  unsigned int seed = 123;   /* Initializer for rand() */

  /* Use command line parameters if supplied */
  if ( argc == 3 )
  {
    limit = atoi( argv[1] );
    seed  = atoi( argv[2] );
  }

  /* Initialize the random number generator */
  srand( seed );

  /* Loop limit times, printing one random integer per iteration */
  . . . .

  printf("\n");
  
  return 0;
}

In this program, the limit and the seed are command line parameters (although default values are supplied). See the answer to puzzle L22 for an explanation of these.
