  if (n < 0)
  {
    printf ("error1!\n");
    System ("PAUSE");
    return 1;
  }
  else if (n <)
  {
    printf ("Equivalent 12-hour time:%2d:%2d am\n", N, m);
  }
  else if ((n >=) && (n <))
  {
    n =;
    printf ("Equivalent 12-hour time:%2d:%2d pm\n", n,m);
  }  
  else
  {
    printf ("error2!\n");
    System ("PAUSE");
    return 2;
  }
  System ("PAUSE");
  return 0;
}

I hope this article will help you with the C language program.
