C vs Perl

[len v]

A recent (Oct 3) Fox Trox comic (Bill Amend ) got me thinking causing me to
edit the origional comic. Bill then had to write a patch, as most C
programers must do.( http://homepage.mac.com/billamend/images/patch.gif )

Where is the C++ version? I don't see it.

Where is the C++ version? I don't see it.

Don't know, but the original C code had an error. There was no new line, so it
would output the following;

I will not throw paper airplanes in class.I will not throw paper airplanes in
class.I will not....

Oh, here's a C++ version

#include <iostream>
#include <iterator>
#include <string>
#include <vector>
#include <algorithm>
using namespace std;

int main()
{
vector<string> v(500,string("I will not throw paper airplanes in class."));
copy(v.begin(), v.end(), ostream_iterator(cout,"\n"));
return 0;
}

Mine is better

#include <iostream>
#include <string>
#include <algorithm>
#include <iterator>
using namespace std;

int main ()
{
fill_n (ostream_iterator <string> (cout, "\n"),
500, string ("I will not throw paper airplanes in
class") );
}

Yes, and I could implement a language called FoxTrot that would have the
following program:

Do it

translate into code that wrote "I will not throw paper airplanes in
class" 500 times into stdout. But I wouldn't guarantee FoxTrot would be
useful for anything else.

IOW, one-off cases like these are useless for comparing elegance of
languages.

Hmm, there's more includes than lines, what's the world coming to

The author of the comic received the same ridicule regarding the
error.... --> http://homepage.mac.com/billamend/ Half way down you will
find his patch.


umm.... I don't think I can fit the c++ version on the chalk board.

What about Julian Albo's (sorry Julian, don't know how to put the accent on in Moz...)?

His is three lines shorter:
doesn't need #include <vector>
uses the implicit return 0 from main
doesn't need to declare the vector I used

Would that fit?

I just hate spilling errors.

Note to self. Find spell checker for vi.

Looks like I spelled it wrong on the web site too. I've always maintained
that a programmer does not have to spell correctly, just consistent, either
right or wrong - the syntax checker does not care.

That just might do it. I'll try and repost the link.

I wonder if I could fit COBOL, Fortran or Java code in there too. Ouch. My
brain just started to hurt. It's been awhile.

I see your point and that is exactly what Perl is all about. If your
FoxTrot implementation had something to offer the community then FoxTrot
would be added to Perl.

Perhaps you could help me out? I've been trying to remember my C and C++
code, it's been about 5 years. How do I swap the values of 2 strings?

Could you define "value of string", please?

Sure --
I was using a string (scalar) as an example, it could be any two basic types
(ex: int's, char's, float's, reference's, arrays etc.) However, in keeping
with the original question:

CString m_firstName;
CString m_lastName;

put the value of (contents of, address of) m_firstName in m_lastName and put
m_lastName in m_firstName.

Len

There is no CString in C, C++ or Perl.

To clarify my question:

char a[] = "C", b[] = "C++";

char *a = "C", *b = "C++";

Are a and b strings? What are their values?
How would *you* swap their "values"?

Perhaps I'm not reading it correctly:

A string would be a scalar. In Perl it would be $a and $b
http://www.perl.com/pub/a/2000/11/begperl2.html No need to declare the
type. Scalars can be a numbers, text, references to a scalar, references to
an array, or references to a hash, or references to a sub (a function or
method). And no need to pre-declare the variable prior to its' use.

Example of strings (scalars) in Perl:

$a = 'C';
$b = 'C++';

$tmp = $a;
$a = $b;
$b = $tmp;

However this is too much work for me, so I was thinking more like:
$a = 'C';
$b = 'C++';

($a, $b) = ($b, $a);

or

($a, $b) = ('C', 'C++');
($a, $b) = ($b, $a);

CString is part of MFC which is *not* part of C++.
Ever heard of std::string?

Example of strings (scalars) in Perl:

$a = 'C';
$b = 'C++';

$tmp = $a;
$a = $b;
$b = $tmp;

std::swap(a, b);

That is what I'm looking for. Thank you

My compiler really doesn't like it when I spell freind wrong.
