Write your reply.

assistant: Hi Auke,
    Well spotted! The disgusting thing is that it compiled and ran when
tested .... :-(
    I give in. Where is it? :-) Presumably it should have said:-
int cprintf(char *format, ...) {
    int c;
    va_list arg_ptr;
    va_start(arg_ptr, format);
    c = vfprintf(stdout, format, arg_ptr);
    va_end(arg_ptr);
    return c;
}
    If there are any readers who can't put these two messages together, then
I am not going to do it for them. However some implementations of cprintf()
do much more than this, and some do it differently.
    _getch() is just:-
int getch(void) {   return _bdos(7,0,0); };
    or the local equivalent (hardware/os/compiler) as far as I can see.
    All I can say is that cprintf() was in the book like that, so I'm not the
only one whose brain occasionally switches off. :-) No excuse, Guv!
Best wishes,
Bill.

Write your reply.

assistant: Hello Mark,
    I've had another fiddle with the TSRs for PCC. Once they're brought up to
date for a recent version of MsDos they start working again.
    Since PCC is a bog standard K&R compiler, the routines
can be modified for any MS-Dos compiler. Whether it's worth it is for you to
decide.
    There's little point posting them here even though they are public domain
because interest in TSRs is marginal, and they're long and full of inane
comments. Tell me where to send them. :-)
Best wishes,
Bill.

On 09 Apr. 98   2:46 Kurt Kuzba wrote to Russ Wuertz...
     Your opinion is that getStream(1) as defined in stdio.h cannot
     be used to capture those ANSI escape sequences so that I can
     print out with cprintf.   I have cprintf here in its C function
     form so that I could change it around (re-compile it and put it
     back into my lib).
         I realized I did not have enough understanding of how
     #define stdout getStream(1)  worked to filter my input through
     that stream.
         The problem with using anyone elses ANSI program to decode
     excape sequences is portability.  Line feed charactors, screen
     width and other little things like that keep showing up.  "If there
     is a fuction already USE IT."  Isn't that what supervision always
     says?  I will have to look over Vidmgr.c again in Snippents.

assistant: Hello Bob, I am getting unexpected results with editgets. When I
  set the cursor at the start of a line and call it with
  editgets(event_header.Event_Title, 80, NULL);
  then the cursor is on the line below the default string, while if I
  call it with a length of 79,
  editgets(event_header.Event_Title, 79, NULL);
  then the cursor stays on the same line. Is there any simple way to
  use it with strings of 80 or more characters, with it not shuffling
  the cursor down in that fashion?

user: You are replying to Bob Stout & Auke Reitsma about "Stucture tags".

Write your reply.

assistant: Hello Bob & Auke, the basics of a structure and accessing it are
  not too difficult, but I have some questions about some of the
  parts.
  I have given the struct both a stucture type name and a structure
  variable, and then give the working instance in the program yet
  another name which is an array of structs. What is necessary, and
  some of the simpler why? I can initialise it with a series of calls
  to memset, but is it possible to do so more elegantly? I tried
  using the sizeof() operator, but got a compilation error from my
  efforts.
struct STAGE_DATA
{
    char stage[10],        /* stage number (letter for transport) */
         scoring[10],      /* score or not */
         open[10],         /* time stage opens */
         duration[10],     /* allowed time for scoring */
         length[10],       /* road distance in Km */
         passages[[10],    /* number of passage controls */
         informations[10], /* informations on stage */
         max_speed[10],    /* for speed limited transports */
         restrictions[10]; /* other restrictions */
}   stage_data;
  While the above example has all the character strings of uniform
  length, that will change as I find what lengths are actually
  needed. I will have another structure with binary data, but I
  expect to store to disk as text that can be proofread with almost
  any file viewer.
  I need meaningful names of reasonable length, but I do not want to
  have to devise more than I really need. What does the structure
  type name give me that the structure variable does not and vice
  versa.

assistant: Hi Tom,
You wrote to David Noon:
As there is no need to compare an element with itself you can remove a
redundant check from the start of the inner loop and a redundant outer
loop by changing the loop parameters to:
for (i1=0; i1<limit - 1; i1++)
   for (i2=i1+1; i2<limit; i2++)
      if (elem[i1]>elem[i2])
Indeed it does :-)
With my change the total number of compares for 5 elements is
4 + 3 + 2 + 1 = 10, or 1/2 * n * (n-1) which can be re-arranged
to 1/2 * n**2 - n.
This is the number of compares Knuth gets in his analysis of "Straight
Selection sort", which has the same loop construct (page 141 of Vol 3).
So we have the support of a published analysis :-)
This is also the upper bound (or without the early exit flag the actual
number) of compares in bubble sort.

Hi George,
Can't see, actually. [Literally. I hadn't treated my contact lenses when I
read Tom's message, so I was "flying blind" so to speak.]
I "saw" the inner loop starting from zero.
We open a whole new can of worms once we introduce multiple sort keys.
Especially if some are ascending and some are descending. This makes custom
comparisons worthwhile. The efficient implementation of same will be worthy
of another message thread, same time next year. ... :-)

Yes. It depends on the amount of disturbance to the data set (the
crossover point for data set size varies in inverse proportionality to
the amount of disturbance), but for small disturbance (<2.5% elements
displaced @ 250 elements) it is faster. I've tested shellsort (ssort()
in SNIPPETS) against the fully tweaked quickersort (qsort() from
SNIPPETS) and both have similar timings on already ordered data.
I need to do more work on my test harness before I post it. I know of
some structural changes to make it postable, there is some poor codeing

It's not "better than qsort()", in certain circumstances it's faster
than the basic quicksort algorithm, but with all the "tweaks" to the
algorithm applied, to get "quickersort", there are very few
circumstances where shellsort is faster than quickersort.
