Re: OT: Why is C so popular?

Perl. I personally find it quicker to code a dirty fix in C than anything 
else and would not really consider shell programming for anything other than 
glue for a sequence of other commands.

Just my 2 bits.

 

Another great example on why the variety is a good thing. I agree on the 
C vs shell. The only way I write shell scripts is by example. I don't 
understand it well enough to write a script from a blank page. On the 
otherhand, I _so_ find myself wishing I could use regexp's this way in 
C/C++:

$email_in = 'Anawalt, Jacob; <[EMAIL PROTECTED],com>; runme&';
$vc = 'a-zA-Z0-9'; #Valid username and domain characters
$vd = '.-'; #Valid domain non-characters
$vu = $vd . '_'; #Valid username non-characters (domain plus an underscore)
$email_out = $email_in;
$email_out =~ s/,/./g;
# Look for just the [EMAIL PROTECTED] portion of the email
if($email_out =~ /([$vc][$vc$vu]*)\@([$vc$vd]*[$vc])?/) {
  #Match worked, email is just [EMAIL PROTECTED] portion
  $email_out = "[EMAIL PROTECTED]"; #$1 and  $2 are the patterns \1 and \2 matched 
from the regexp
} else {
  #Match failied, empty string;
  $email_out = '';
}

print "$email_out\n"; #Prints [EMAIL PROTECTED]

If somone else is happier writing a cool  class and some loops or 
figuring out a C++ regexp class to do this, or just some adept use of C 
string library calls, more power to you. :)
