I 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?

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>

I'm wondering how it is possible to read each line from a text file, and then store each line separately in a list, using C++?

I have an old C application in which i am trying to include some STL cointainers. When i use the STL container alone it works fine, but when i include it into a C struct i have segmentation faults errors. I know that it is not a good idea to mix C and C++. Considering this code:
Code:
typedef struct{
int shmid;
...
APPLSPACETYPE applSpace;
[code]...
and how to make a malloc for this issue; something like :
Code:
mem->applSpace.rData.completeGroups2zeroGroup=(map_completeGroups2zeroGroup_type *)malloc((sizeof(map_completeGroups2zeroGroup_type)+1)* sizeof(char ));

View 1 Replies View RelatedI 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.

View 2 Replies View Relatedi have a loop which produces new value everytime it runs. i want to store the results in an array. how can i do dat??
loop is like:
a=0
declare v
while ((....))
do
v[$a]="$r"
let a=a+1
done
while doing this it is not treating v as array but as variable and it is overriding the value and old value is lost..i am using bash shell version 3.00.15
Code:
ls Again the command can be stored in a variable and then executed. Like
Code:
var=ls
&var
The above two codes are the same. The problem occurs when we try to pipeline it. Consider the following problem:
Code:
ls | grep *
works fine...but when we try to store it in a variable and run the command there is an error.
Code:
var="ls|grep *"
$var
how to store this kind of commands in a variable?

View 2 Replies View RelatedI 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.
How do I do this? I wish to store the pictures via a "Browse" button on the webpage, and later display them on a particular page on the site.

View 1 Replies View RelatedSuppose I want to account number of files beginning with abc , I can use "ls 'abc* | grep abc | wc -l", this will return me a number.
I want to store this number in a variable, say var1, so I tried
1. "ls 'abc* | grep abc | wc -l |read var1", but this didn't work as var1 has no value somehow.
2. var1='ls 'abc* | grep abc | wc -l', this just assign the entire string "ls 'abc* | grep abc | wc -l" to var1, which is not I wanted.
I don't want to store the value to a temporary file and then read the value from that file. I think there should be a direct way to get the value, but don't know how. I know in tcsh, one can just use set var1='ls 'abc* | grep abc | wc -l', but it also doesn't work in bash. Can anyone give any clue about this?

I am adding inventory control to our online store here at work and I'm not sure of the best approach.Let's say Customer A and Customer B are both looking at the product page for Product X at the same time, and there is only 1 left in stock. What should happen if both click "add to cart" at (more or less) the same time?hould the last Product X get put "on hold" for one of the customers, and then decremented once the sale is complete? Or should the database decrement the product count, and then increment it if the sale doesn't go through successfully?Is it still possible for both to add it to their cart? Are there any mysql features I can use to ensure both cannot purchase the last product?
