Hi, I have a text file that contents a list of email addresses like
this:
"foo@yahoo.com"
"tom@hotmail.com"
"jerry@gmail.com"
"tommy@apple.com"
I like to
1. Strip out the " characters and just leave the email addresses on
each line.
2. extract out the hotmail addresses and store it into another file.
The hotmail addresses in the original file would be deleted.
Thanks for any help |

To get you started, assuming there are no escaped quotes in between:
while (m!"([^"]+?)"!g) {
if ($1 =~ m!\@hotmail\.com!) {
... do something with $1
}
else { ... }
}
Or if you are using an array:
foreach my $email (map { s!"([^"]+?)"!$1!g; $_; } @email_list) {
if ($email =~ m!\@hotmail\.com!) {
...
}
else { ... }
}
(Note, untested, but should give a starting point.)

You're probably not including the reqired headers. Try
#include <sys/types.h
#include <sys/socket.h
#include <netdb.h

The OP probably is including the required headers, or the compiler would
also have complained without the --std-c99 option. The answer is simply
that getaddrinfo is not a C99 function, and is therefore not declared by
the library when asking for a C99 implementation. |

You have perl solutions so you won't need this. But was an interesting
little snippet:
/* Sort email addresses (possibly for some nefarious purpose) from file
"input" */
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
void error(void) {puts("File error"); exit(0);}
int main(void) {
char line[200];
char *p;
int n;
FILE *in,*hot,*nothot;
in=fopen("input","r");
if (in==0) error();
hot=fopen("hotmail","w");
if (hot==0) {fclose(in); error();};
nothot=fopen("nothotmail","w");
if (nothot==0) {fclose(in); fclose(nothot); error();};
while (1) {
fgets(line,sizeof(line),in);
if (feof(in)) break;
n=strlen(line);
p=line;
if (line[n-1]='\n') {line[n-1]=0; --n;};
if (n) {
if (line[n-1]='""') {line[n-1]=0; --n;};
if (*p=='"') ++p;
if (strstr(p,"@hotmail.com"))
fprintf(hot,"%s\n",p);
else
fprintf(nothot,"%s\n",p);
};
};
fclose(in);
fclose(hot);
fclose(nothot);
}

And you are aware that gcc (no matter what version) is not a fully

Not even with --std=c99.

No I didn't know that. I guess you learn something new everyday.

No problem. They are really just text files, obeying some
formatting rules. fopen, getc, and fclose can access them all.

I think you're right. That seems like a terrible misfeature of gcc. If I
have a C program and I include a POSIX header, I damn well want the
functions from that header, in just the same way as if I include my own
header file then I want access to those functions, without the compiler
getting all holier-than-thou and telling me my functions aren't
mentioned in the C standard.
One solution is to add -D_POSIX_C_SOURCE=200112L as a command-line
option. |

Ever heard of mathematics? Number systems?
A typical number system consists of:
1) Radix = the amount of different symbols
2) The actual pictures that represent the symbols
Let's take the "octal" number system:
1) Radix = 8
2) Symbols = 0 1 2 3 4 5 6 7
If you want to represent a number that is greater than or equal to
radix, then you need more than one digit. So in octal, the number
eight is written as:
10
And nine is written as:
11
Here, the "11" is equal to:
1 multiplied by (8 to the power of 1)
+1 multiplied by (8 to the power of 0)
Try another octal number: 2763
2 multiplied by (8 to the power of 3)
+7 multiplied by (8 to the power of 2)
+6 multiplied by (8 to the power of 1)
+3 multiplied by (8 to the power of 0)
Try think now, if you had a number in decimal such as 34, then what
would you do to it to get the first digit and the second digit? I'll
give you a clue, it involves using the radix, i.e. 10, in conjunction
with a mathematical operation such as division. |
