Programming :: Out Of Range Vector Iterator?

Mar 20, 2011

I'm not really a C++ noob at all, but I am a little rusty at the moment. Still, I CANNOT figure out what is wrong with the following code. I'm using Visual Studio 2010.

Code: #include <iostream>
#include <fstream>
#include <vector>
#include <string>

[Code]....

I THINK I got all of the pertinent code. Anyway, it fails at the *** line. I CANNOT figure out why. If I modify it to be linein.size()-30, it STILL gives me an error. That makes zero sense.

Programming :: Bash Script To Ping A Range Or Own IP-range?

Apr 11, 2011

I want to build a bash script, which can ping a range IP adresses which will be filled in by the admin. If there is no IP-adress filled in, then the script must ping the subnet where the system is logged on. So if my ip is 192.168.1.6, then the script must ping from 192.168.1.1 till 192.168.1.255 Or else, if there is given a beginning and ending ip it must ping that!

The first part of the bash script is to ping a given range (see below). But there is one problem, how can I tell the script to ping from $begin till $end, [..] is of course wrong! But what must be filled in there???

echo "Enter beginning IP-adres:"
read begin
echo "Enter ending IP-adres:"
read end
ping -c 1 $begin [..] $end

The second part is to find my own ip and ping the whole range.. How to do that? I only can find my own IP, but I cant ping the whole range,, how to do that?

#!/bin/bash
ifconfig | grep 'inet addr:' | grep -v '127.0.0.1' |
cut -d: -f2 | awk '{ print $1 }'

Programming :: Passing The Char * Vector Argument?

Jun 19, 2010

I am trying to simulate a shell. So what I do is checking of having the parameters from standard input, suc as "/bin/ls -l /home/france/Documents", and then passing them to function execute, which at some point calls execvp(argv[0],argv)The problem is that I don't succeed in using these arguments, while if I call execvp(paramList[0],paramList) it works!!!! Where paramList is exactly what I would put on standard input, but defined statically.

Code:

#include<unistd.h>
#include<stdio.h>
#include<stdlib.h>
#include<string.h>

[code].....

Programming :: Converting Vector Of Bytes To String C++

Mar 4, 2011

I have a vector of octets that needs to be converted to a std string. I'm currently doing it this way:

Code:
stringstream ss;
for (unsigned int i=0; i < data.size(); i++
{
ss << data[i];
}
string s_data = ss.str();

This works, but is there any better way to do it?

Programming :: How To Tell Java To Print 20 When Value Is In That Range

Jul 28, 2011

I've just started programming at my university and I'm finding it a bit hard to get started. I've been given this for homework.Given 2 integers, a and b, print their sum. However, sums in the range 10..19 inclusive, are forbidden, so in that case just print 20The problem I'm having is that i don't know how to tell java to print 20 when the value is in that range.

Software :: Gnuplot - Combining A Linear Range And Log-scale Range In The Same X-axis?

Apr 24, 2011

I want to plot a set of data in only one plot.The problem is that some points of the data should be better plotted in a linear scale (lets say 0 to 100,000) but there are other data points that, exceding the value 100,000, would be better plotted in a logarithmic scale, as they goes in the range 100,000 to 500,000,000. Let's say the data is:

Code:

X Y
0 100
10000 80
20000 75

[code]....

Is there a way to plot all these points in the same plot in only one X-axis showing two different ranges in that axis: linear: 0-100,000 logarithmic: 100,000 - 1,000,000,000?The axis would be read, for example, as:

Code:
|-----|-----|-----|-----|-----|-----|-----|-----|-----|
0 20k 40k 60k 80k 100k 1M 10M 100M 1G

(The abbreviations k-M-G are not the important point. Just shown for clarity)

Programming :: Sed Print Range From Pattern1 To Pattern2?

Jun 14, 2011

From a file I want to extract a range of lines by patterns. I've used variations on

Code:
sed -n -e '/^BashNotes/,/^EndOf[A-Za-z]*$/ p' -e '/^EndOf[A-Za-z]*$/ q' Notes

So, I want to extract lines starting from one whose first word is specified, in this case "BashNotes", and ending at the first line consisting of the single word "EndOf...", which in this case would be "EndOfBashNotes".

Either I get no output at all, or it prints from the start of file to the first EndOf..., so the problem has to be with "^BashNotes", e.g. remove the "^" and it accesses an earlier occurrence of "BashNotes" that is in the middle of the first line of the file, and prints to the first occurrence of "EndOf...".

So why should a "^" in the "from" pattern be objectionable, when it is acceptable in the "to" pattern and the "quit" statement?

Programming :: Shell: Give A Range Argument To 'for'

Feb 20, 2010

Feel free to just link to another thread where this is (pre)solved; I can't search the forum for the word "for," because it's too short (or maybe the search engine dislikes prepositions).

Is there a way to give the 'for' command a range? Here's what I mean:

Code:
#for i in (1-5); do echo $i; done
Certainly, meat space user; I understand exactly what you're thinking.
1
2
3
4
5
True, I realize I could use

Code:
COUNT=1 ; while [ $COUNT -lt 6 ]...

...but if I can avoid the extra preparatory step I'd prefer to do so.

Programming :: Bash Script - Test Variable Against A Range?

Jan 28, 2010

I am fairly new to bash scripting, and I am trying to test a variable against a number range (1-3). This is what I have used so far: The user enters a value, then

while [ "$PROV" != "1" ] && [ "$PROV" != "2" ] && [ "$PROV" != "3" ] && [ $COUNTER -lt 4 ] || [ -z "$PROV" ] && [ $COUNTER -lt 4 ]; do
clear
echo

Is there a cleaner way to do this? Something like:

while [ "$PROV" != "1-3" ]&& [ $COUNTER -lt 4 ] || [ -z "$PROV" ] && [ $COUNTER -lt 4 ]; do

Programming :: MySQL Year Field Range Too Limited

Jul 1, 2011

In the MySQL database for one of my programming projects, I used a "YEAR(4)", because I wanted the column to contain four-digit year values. I discovered, though, that this type only allows values from 1901 to 2155, which is not workable as some year values are previous to the twentieth century. But I do not want a "DATE" type because the month and day are of no interest to me. What type should I convert to that would be the least radical change in data type, while giving more range?

Programming :: Perl - Stop Range Search At End Of An Array?

Dec 7, 2010

I have data that looks similar to this -

Quote:

John Smith (Address)
123 Main St
Unit 1

[code].....

So I need everything between each name, but I am not guaranteed that each time I match a name that I will have the same amount of lines, so I do a range pattern search line this to get all lines, no matter if there is 5 or 10 or 15. I simply do a loop that goes through the whole array until I hit the match, and this is my search pattern.

Code:

if ($LINE =~ /^s+$SELECTED_NAME/ ... $LINE =~ /(Address)/) {
push @ADDRESS_INFO, $LINE;
}

This works perfectly... until I hit the end and it doesn't get its final pattern match because it's at the end and there is no next entry with a (Address) line. So as a 'hack', I ended up inserting a final scalar at the end of the array that just says (Address) so it knows it's at the end. Ideally though, I'd like to do an "or" statement that says search for Address || return true if I hit the end of the array. How would I match on "End Of Array" essentially?

Programming :: Getting Error 'couldn't Compile Regular Expression Pattern: Invalid Character Range'

Nov 19, 2008

I'm having a bit of trouble with a regular expression I'm trying to write and I'm not sure if it's something Tcl specific or my lack of regexp understanding.

[Code]...

I get a number of strings passed to a proc in the format 3|x where x is a number, either 0 or within the range 5-12. My understanding is that that regexp will match the literal '3' followed by a '|', the escapes the special meaning of |, and then 0 or, because of |, a number within the range 5-12. However I'm getting the error 'couldn't compile regular expression pattern: invalid character range'.

Slackware :: SVG Logo (GPL) Editable Vector Version?

I was fiddling with some svg icons and I needed a slack svg logo: looking on the propaganda page, I spotted this jpg that looked like a nice and clean candidate. So I fired up inkscape and tried to manually trace a (manageable) svg version out of it. Then I thought that maybe an editable vector version of it can be useful to someone else and, as asked by Pat, I release it here under the GPL. [URL]. (gotta say I haven't looked around if any other logo svg has been posted before, but, clicking on the "Click Here to Find Similar Threads" found this funny one )
