assistant: Hello ``Richard
Replying to a message of ``Richard Claypool``  to ALL:
char ch
ch is a bucket in which to put some data.
ch = 'A'
ch now contains some data, the letter A
char *ch_p
ch_p is a bucket in which to put some data.  However, this data is usually an
address.
ch_p = &ch
ch_p now contains some data, the address of ch.  In other words, it points to
ch.
Both ch and *ch_p will now give you 'A'.
However, thinking of pointers as just containing addresses can be misleading.
 You can add 1 to a pointer and it will not neccessarily increment the
address by one.  For instance, if you have a pointer to an int, you don't
need to know how big an int is.  If an int is two bytes long or maybe 4 bytes
on another system, adding 1 to a pointer will move the requisite number of
bytes to contain the address of the next integer. It won't just add 1 to the
address.

Write your reply.

assistant: Hi All!
A while back I decided to take all the functions and bits of code I use most
often (such as showing and hiding the cursor, screen fading, my encryption
and decryption routines and other stuff I have developed) and put them into a
library file using TLIB. All good so far - everything works apart from:
One of my functions called clr_string needs to have the location of a string
passed to it. For example (I know this doesn't work!):
        test_str[] = "This is a test";
        ...
        ...
        clr_string(/* need to pass the location of test_str to function /*);
                   ^ What would I put here as an arg? char *, char &???
My guess is I do that with a pointer. I don't know a damn thing about
pointers!! Could someone help me out here, please? <I have Borland C++ 3.1
DOS and I'm not bothered about ANSI portability!>. Thanks.

assistant: Hi Simon,
This is not so good, malloc is a better way to reserve memory.
Shouldn't the while be: while( finished); or while( finished != 0); ?
Also using two fgets to get to the next available string is bad practice,
what if the t_pos results in a position half way through the last line?
I can't see anything else wrong at first glance. If it only crashes
occaisonally then it is like to be one of the above problems causing it.

 [3d rotation]
First one thing, don't swear. It may not bother you or me but some people
find it offensive and it is moe likely to get you shouted at than helped.
Do you want the equations or a mathematical dresciption of how they work? If
the latter I have no idea if the former then:
 C = COS( angle of rotation)      S = SIN( angle of rotation)
Rotation about the Z-axis:
 ( Xnew, Ynew, Znew ) = ( Xold * C - Yold * S,
                          Xold * S + Yold * C,
                          Zold )
about the X-axis:
 ( Xnew, Ynew, Znew ) = ( Xold,
                          Yold * C + Zold * S,
                          Zold * C - Yold * S )
about the Y-axis:
 ( Xnew, Ynew, Znew ) = ( Xold * C - Zold * S,
                          Yold,
                          Xold * S + Zold * C )
You could also use matrices but this way is easier. I don't think it's
neccessary to know how they work just how to use them, you could try
MATHS.ACA or MATH for an explanation of how they work.

Write your reply.

assistant: Hi Bill,
I picked up a tutorial on C++ the other day and I think I agree with you.
There are some nice features that should really have been included in ANSI-C
such as anonymous unions in structures, the '::' thing where you can have
global and local identifiers of the same name and the ability to declare a
variable anywhere. The new comment system is quite nice too. I see no
advantages in the class construct except that it does help to prevent sloppy
programming, and it does add overhead in terms of program execution speed. I
don't see how it can hasten application development.
That's my opinion anyway.

assistant: Hi Bob,
You wrote to Alan Clifford:
They can be required in invoice calculations though...
The most common occurance of fractional pence is in VAT ([Value Added
Tax] which is more or less equivalent to the US state Sales Tax)
calculations. The current UK rate is 17.5 per cent and the official
rules are that when it is calculated on a per line item basis either
calculate to 0.5p (round to closest value) or 0.1p (round down), with
any fraction of a penny in the final total being ignored.
It's amazing how many commercial accounting packages do not follow these
rules, and work totally in pence, with the result that the difference in
VAT charged from the amount that should be charged if it was calculated
correctly being several pence as a result.

Hello little meerkat.
Possibly - it was a few years ago when I last used it.
Not just the reason its slow - it's poorly opimized. When I switched to
TCC3, the speed increase in both compiling and execution was /huge/.
TCC's also Ansi compliant (to a degree) so when I ask for help in here,
I get suggested the functions that work.
Remember a few years ago I asked how to change a text colour? Everyone
suggested textcolor() or textattr(). PCC uses scr_attr(col). Makes
for hard work.
Not use it!
BTW, I do like PCC. I recommend it to anyone who's not sure if they

George...
  I included your whole message since someone else already called me on this
and I think it bears repeating. The way I do this sort of thing is (using
SNIPPETS)...
#include "snipmath.h"
        long sale;              /* expressed in pennies                 */
        double tax_rate;        /* expressed in decimal, e.g. 1% = .01  */
        sale = dbl2long((double)sale * (1.0 + tax_rate));
  Note that dbl2long() is a specialized version of the dblround() function
which always rounds doubles properly to the closest integer - see
DBLROUND.HOW, also in SNIPPETS, for more information on how it works.
  I find the use of dblround() and its related functions, such as dbl2long(),
to be invaluable in a lot of calculations involving floating point data. The
traditional macros (such as in SNIPPETS' ROUND.H) tend to be both inefficient
and subject to error at the limits of integral precision. The dblround()
function, OTOH, optimizes well and uses the information in float.h and
limits.h to assure proper operation over the entire range of floating point
values.
