Programming :: C++ - Store A Text File In A Data Structure?
May 25, 2009I am writting a program that reads a text file (music.txt) & stores it in a Data Structure. I am a novice learning over the internet so I this is something I have never done. How do I do this?
Quote:
Write a program that reads the data from the music.txt file and store it in a data structure. To implement this data structure you must use an array of songs and each song must be represented by a struct with appropriate fields. So far all I can do is open to file to read it (very simple I know) but so far is it correct?
Code:
#include <iostream>
#include <fstream>
#include <strstream>

Programming :: How To Save Text Data In Binary Format Using C
Feb 20, 2010I have created a file using open() and written data to it. Data appears as normal characters in the file. How to save these characters in a binary format in that file using C language? Here I mean that the characters should be actually stored as 0 and 1. Do I have to convert the whole data using some function or there is some standard way to do it in Linux?

Nov 2, 2010I am trying to store the results of my code to a separate text file.But the problem is, as my results comes from a loop, my text file shows only the last result, not all of them.Like if the loop runs 5 time the text file shows the result for the 5th step.But i need to store all of them (1 to 5).Can I use awk to print the output field and store to another file and creat a new line so that the next output field goes to a new line?(just an idea, dont know).

Programming :: Store The Data In Program In A Map Of Priority_queues?
Jul 30, 2011I am trying to store the data in my program in a map of priority_queues an I am having a bit of trouble doing it. basically I am storing activities (ie watching tv, eating dinner, playing ping-pong, etc) and I want these event grouped by the day that they happened on.
my first thought was to use a multimap where the key is the date, and the value is the activity, however I would like to keep the activities in a specific order. I have tried to find the proper syntax for this but have frustratingly come up empty. Even google provided little assistance.

General :: Where Does ITunes Store Its Stuff - Copy Its Data Store To An External Drive
Dec 8, 2009I have two students whose windows laptops are riddled with malware and not working properly. They want me to help them install Linux (which we use in school), but they are concerned about their iTunes.
Having avoided iPods as "defective by design", I know nothing about iTunes whatsoever. However I remember reading about DRM locking and such problems that have me concerned that I won't be able to do it.
Where does iTunes store its stuff?
Can I copy its data store to an external drive, and then into a linux home?
Then will it work on wine, or can another manager (rhythmbox etc) access the itunes data?
Alternatively, if I partition the drive and install linux, can rythmbox/wine/something access itunes data on the win partition?
Supposing they are buying music through iTunes, what will happen to that account?
Finally, one of them has an iphone. Does that work with linux?
Ironic that an apple application is blocking migration away from windows.

How can I get this on a python program so I can manipulate it as an array?

Server :: File Server Machine To Store All Data So Being That Have Got Four Identical SATA Hard Drives?
Jan 25, 2011I've got 4 identical 1 TB drives and would like to use them in a software RAID configuration on my home server. I'm running Debian Linux using 'mdadm' utility to manage the software RAID. I don't know how much I've read is fact or dated or even false so I decided I would ask here to get help from people who know more about this than I do. This is essentially just a file server machine to store all my data so being that I've got four identical SATA hard drives, I was thinking about doing RAID level 5. I guess I'll start here and ask if that is the recommended level of RAID. I think RAID level 5 will be fine for my general server usage. My second issue is partitioning the four individual drives to get maximum performance / space from them. Basically just asking here how would you or you recommend I partition the drives? I was thinking about doing three seperate partitions per drive:
/dev/sda1 = 4 GB (swap)/dev/sda2 = 1 GB (/boot)/dev/sda3 = 995 GB (/)Now from that partition schema above, obviously all the types will be 'fd' for RAID and the partition for /boot is going to be bootable. My confusion is that I read Grub doesn't support booting from RAID 5 since Grub can't handle disk assembly. If /dev/sdx2 (sda2, sdb2, sdc2, sdd2) are partitioned for /boot (bootable), how would you guys configure this RAID to match up equally? I don't think I do a RAID level 1 on 4 identical partitions, right?
Programming :: Save / Load Data Segment Of Dynamically Loaded Shared Object Library?
Aug 25, 2010Our application uses a dynamically loaded shared object library (codec library) to compress and decompress audio streams.
There happens to be several static and global variables in this shared object library. Hence it is not possible to process two interleaved unrelated media streams using this shared object codec library because each stream corrupts/changes the contents of these static/global variables.
Is there a way through which a context save (save contents of data segment of shared object) and a context load (load previously saved contents of data segment of shared object)operation can be performed on the shared object library. This way the context for each media stream can be saved and loaded before and after processing the "other" media stream respectively.

Jan 13, 2010I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.

Programming :: Formatting Fields And Text Being Displayed From Text File?
Feb 9, 2011I want to display the contents of a particular log file (simple text file, I mean in Linux). But there is a problem: The contents need to be organized in a fixed format. Have a look at this log file:
sampleLog.txt
Code:
User Name: XYZ
Reported Problems Description: Blah! Blah! Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah!
[code]....
So, while displaying the contents of above file on a web page, I want to format the field names found in the log file: User Name:, Reported Problems Description:, and Remarks:. These fields may contain a variable length of text and no specific line number is assumed for them to appear on.
The desired output should look like this:
User Name: XYZ
Reported Problems Description: Blah! Blah! Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah!

Well, what I am trying to do may sound wierd to some of you. The filed "Reported Problems Description:" can possible contain text which embeds colon (.
