There is NO excuse for writing ANYTHING in C these days.......none!
I disagree. While it is good to form an opinion and have a
favorite language, that does not mean other languages are useless.
C is, and has been useless ever since C++ became
standardized. and I'll say it again, There is NO point in
writing anything in C these days. C++ is simply a better language, period
C is, in fact, a very good language. It is often used for writing
device drivers, for example. Sure, one could also use C++, but C
is a perfectly acceptable choice.
Victor. Have you opinion but don't degrade the choices of others.
It isn't necessary.
I wasn't degrading anyone, and it's NOT an opinion, it's fact
No, Victor, your statement is NOT fact. Saying "There is NO excuse
for writing ANYTHING in C these days.......none!" is simply not
true. Sure, C++ may be a superior language to C but, if one does
not know how to program C++ yet they do know how to write code in
C, then C is a perfectly acceptable choice.
This forum is supposed to help those of us who do not currently
know C++ and would like to learn. Statements/attitudes like yours
make that process more difficult.
One has to question WHY they know C and not C++. Absent thousands
of lines of code in C to be maintained, there is no excuse for using
the language.
And why does one have to wonder why "they" know C and not C++? How
about "they" learned C long before C++ ever existed?
And what about the millions of lines of C code that currently exist?
One cannot simply throw it all away and re-write it overnight. It's
out there, in volume, and it's doing the job it was meant to do.
Perhaps your over-zealous acceptance of C++ over C is because you
never learned C. Good for you. Some of us aren't that fortunate.
And, perhaps you DID learn C first and then converted to C++. Also
good for you.
I am not a programmer/software developer by trade. I program because
I enjoy it. I started years ago programming in ALGOL then BASIC,
COBOL, Pascal, PL/1, and other languages. Eventually I learned C and
liked it far better than the previous languages I had worked with. I
still like it. It does what I need it to.
Agreed, I SHOULD learn C++. And I would like to do that, but I simply
don't have the time to devote to that effort full time. So I spend
time here reading the messages hoping to pick up some tips and ideas
about the C++ language. I've gone back to some of my old C code and
tried to re-write it in C++. But it's a slow effort given the time I
have to devote to it.
P.S. The program you wrote for me fails. I asked for a fix, but
received no reply.
then read your damned mail..... David gave the fix, and I replied to him
btw, sending a stupid .jpg file isn't the normal way to indicate a
failure.... there was NO text in the message, and I usually trash
EMails with no text and attached "pictures"
Victor,
Since you seem to be fixated on details, this is a message board,
not a mail system. Sure, I read David's comments on your code and
your reply to him. But the message was not directed to me and it
was not obvious that the <exception> -> <stdexcept> issue was
supposed to be the "fix" to your code I could not get to work.
I suspect you're the only person who didn't "get it" on David's fix.
Seriously? I doubt it.
That was a separate exchange between you and David. And, BTW, I
made that change. It now compiles without error, but it does not
run. Selecting "Run" (or double-clicking the program ICON) does
NOTHING. It does not even momentarily pop up a DOS command box.
Nothing. Nada. Zip.
I'm sorry, your IDE works differently than mine. The program is NOT
designed to be run by double clicking an ICON. It's a SHELL
program. So, you go the a command shell (DOS window to some folks,
though DOS is dead, thankefully, and has been for some time) and
type the name of yoru program followed by the words you want scored.
I tried several ways. I ran it from the IDE (Execute->Run), I tried
it from a command shell, and I tried double-clicking the program
ICON. In all cases, absolutely NOTHING happens. So, I'm not going to
worry about it.
Also, I put the JPG there because "a picture is worth a thousand
words" and it showed exactly what the errors were. I'm sorry if
that's not standard practice here. Calling it "stupid" has no positive benefit.
And there WAS text in that message. Quite a bit of text which you
ignored. I cut it from the previous message and I'll paste it here.
Maybe you can comment on it now?
You added NOTHING to the text in your reply with the .jpg, just a
replay of my message and a picture at the bottom (which shows up as
a link in my mail program (Eudora) and the name of the file fo rthe
picture is a0a602c.jpg hardly something to indicate it might
be related to the situation at hand.
Keep in mind, please, that I have extensive experience with C but
none in C++. I'm on this board to, hopefully, learn the workings of
C++. This board (and others) are meant to help, not degrade,
others. It seems many of your posts DO ridicule people who seem
"inferior" to you. And, when it comes to C++ coding I'm sure we
are. If you want to be a hotshot, fine. But why not use your
knowledge to help others rather than tell them how stupid they are?
That's why we are here. To learn from those who know.
I want to learn. I don't think I post stupid questions. I never ask
for someone to write my code.
Here are my comments from the prior post (sans the JPG). Comment
nicely, if you will, please. I honestly would like to learn. I
think you have the knowledge to help.
NO such comments as follow were in the message.
Actually, yes, I DID add the text. And, I also use Eudora as my mail
client. I could see the text in the post. That's where I got it from
when I copied it to paste back into the follow-up post. Look again.
It's there.
I'd be more than happy to do a screen shot of it and send it to you.
But, you don't like images. So ...
"Errr, Thanks, I think. It's no wonder I stick with C and not C++.
learn, and write better safer code.
I thought C++ was supposed to make things easier!
it does
But there are WAY too many things hidden here.
NOTHING is hidden
[It's frustrating for a beginner.] Some examples:
for_each(argv+1, argv+argc, score_word);
How do I know what score_word will be given as arguments?
well, you COULD read the comments I put before score_word
Let me rephrase this. As for_each runs, what does it feed to
score_word as its' arguments. This is what I mean by "hidden". There
are a lot of assumptions in that call that aren't obvious.
Nevermind. I give up. I guess I'd better go get a book and read it.
It'll be more friendly.
What if score_word took more than a single argument?
it can't (as the general case) for_each is "designed" to call a
single arg function for each element in the range.
How would the for_each function know?
see above
What would it pass?
see above
(Is for_each an internal, standard class?)
1st one presumes that you've actually read something about the
language. We have a list of books we recommend the 2nd one on the
list the ONLY "must have" covers this like a blanket. The list can
be found at http://rudbek.com/books.html
and no, for_each is not internal nor a class.
it is found in the standard header <algorithm> and it's an algorithm.
catch (not_a_letter& e)
{
/// output whatever error message decided at the
point the error was found
cout << e.what() << '\n';
}
Again. WHAT!? not_a_letter is defined as a structure.
not_a_letter IS a struct. Here it is used as a type to tell the
compiler what e is (well the & tells it's a reference to the struct)
The "catch" uses it with an argument e?
yes, catch (part of try/catch) takes an argument. The type of thing thrown.
and then cout uses the argument e. How am I supposed to know that
the argument e has a method what()? This is VERY confusing!
It's part of inheritance.... std::runtime_error has a what()
method, since not_a_letter publicly inherits from
std::runtime_error it also has a what()
Until I have the time to learn all the hidden classes, etc. I'll stick to C.
IMO, you're a fool to "stick with C" because you can't make the
effort to learn something new.
Thanks for the example, though.
DevC++ shows the folllowing errors. It even complains about struct
not_a_letter not having a member what, as I questioned...
I dug out my CevC++ (4.9.9.0) and it compiles just fine, and I can
