My .csv file is like:
Bone,origin,deep/superficial,location, action.
with list of 38 bones.
This is my main.cpp:
#include <iostream>
#include <fstream>
#include <sstream>
#include <vector>
#include <cstdlib>
#include "Action.h"
#include "Action.cpp"
[Code] .....
For action, if user enters action, it will output the bones involved with that action.
For strengthening, if user enters location, it will output bones involved with that location.
For dagnostic, if user enters bone, it will output location of bone and whether bone is deep/superficial.
How I could search in csv file for these.

The program then asks the user for a search string, which may contain white space. The program should search the file for every occurrence of the search string. When the string is found, the line that contains it should be displayed in the following format
nnnnn:Line Contents
That is the line number of the line, 5 columns wide, right justified, followed by a colon, followed by the contents of the line.
And this is what I've got so far:
Code:
#include<iostream>
#include<fstream>
#include<string>
#include<iomanip>
using namespace std;
int main(int argc, char *argv[]) {
ifstream inFile;
string fileName,
[code]....
But this doesn't work. It prints everything in the file, not just the lines where the string is found.

So I'm doing a kind of banking system. Atm I've got the user able to create an account and set the balance of it, which is written to a .txt file. However, I would like the user to be able to enter their account no. and the program to cout the account info on the screen. I will be adding more to the program later, but until I work out how to search for values in a .txt file, and print out values on that line I'm a bit stuck.
Code:
Main.cpp -
#include <iostream>
#include "create_account.h"
#include <fstream>
using namespace std;
int menuin;
int main() {
create_account creataccObj;
[Code] .....
Sample .txt file -
// Account_no - Balance //
1001 140500
1002 150600
1003 18600

This is line one
This is line two

How do I go about writing a program that will print a line of text (e.g. "This in line two" on the console screen?
All I can seem to do is display the entire text file.

The Objective Of This Program Is To Create A File To Write Text And Read Back The File Content. To Do That I Have Made Two Function writeFile() To Write And readFile() To Read.The readFile() function works just fine but writeFile() doesn't.
How writeFile() function Works? when writeFile() function Execute It Takes Characters User Type And When Hit Enter(ASC|| 10) It Ask "More?(Y/N)" That Means What User Want? Want To Go Next Line Or End Input?
If "Y" Than Inputs Are Taken From Next Line Else Input Ends.
But The Problem Is When Program Encounters ch==10 It Shows "More?(Y/N)" And Takes Input In cmd variable.If cmd=='Y' I Mean More From Next Line Than It Should Execute Scanf Again To Take ch I Mean User Input.But Its Not!!! Its Always Showing "More?(Y/N)" Again And Again Like A Loop.
Code:
#include <stdio.h>
void writeFile(void);
void readFile(void);
int main(){
[Code].....

I have almost a hundred names in a text file that I want to convert to email addresses and save to another file. I seem to have it working, but it doesn't print the full names in the email prefix. The output I'm looking for is Doe_John@livebrandm, but I'm only getting D_J@livebrandm. I'm not sure what I should specifically be reading up on that applies to this directly.
Code:
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
FILE *fpin=fopen("namesIN.txt", "r");
FILE *fpout=fopen("emailOUT.txt", "a");
char first[20],last[20],inbuff[1500];

I am writing a simple file/text parser to read a config file for some code I am working on. It's dead simple and not particularly smart but it should get the job done. The code reads a config file:
Code:
readlength=2500000
start=0
finish=25000000
cutoff=20000
samplingfreq=250000
poles=10
filterpadding=500
}
[code]....
Here is where it gets wierd. You'll notice that there is an unused variable (filepath) in the config struct. This variable is not referenced or used anywhere in the code, ever. Yet if I comment out the declaration of char filepath[1024], the code segfaults partway through the read_config() function.
My best guess is that there is a buffer overflow elsewhere and it just so happens that the memory allocated for filepath happened to be there to catch it up until now, but I can't work out where it might be happening. With the declaration commented out, the read_config() function gets as far as reading the "padding" variable before it crashes. Yet when the declaration is there, then all the variabled are read correctly and everything seems to work.

I have a .txt file which I want to read from and then write a new text file, this time with sorted lines. It is easy to sort one value, but what about sorting entire lines based on one value?
I want to sort the lines based on the FIRST value.
Example text file contents:
values;data
5.01 100
2.9 342
2.69 43534
10.1 43
6.8 45324
Output: Text file containing
2.69 43534
2.9 342
5.01 100
6.8 45324
10.1 43
It's easy to do this if there was only 1 number on each line, but I do I sort all the lines based on the first number in each line?

I have a very big xml file. I read it using by xmlReader. I have problem when i reach to next line:
<title>Abasia<nemod>(-astasia) (hysterical)</nemod></title>
How I can read all that content. I have to have next string at the end: "Abasia (-astasia) (hysterical)".
I tried to use ReadElementContentAsString() for all elements, but elements like this has exception, because it has child element.

WPF window I'm working on. I have a window that has a textbox to enter a name to search a database table for, and when the search button is clicked, the ID for that username will be returned to a separate textbox. The code I've written atm doesn't seem to be working, but it looks fine to me. Here's what I've got;
private void btn_SearchUsers_Click(object sender, RoutedEventArgs e)
{
if (!string.IsNullOrWhiteSpace(txtb_SearchName.Text))
{
SqlConnection sqlCon = new SqlConnection(conStr);
[Code] .....
So, I have the value entered into the textbox to be searched for stored in a variable, I'm selecting the ID from the table when the name in the variable is found, storing the result in a DataTable, and then in my foreach loop, if I find the name (the name column being index 1 in the table), I set set the ID result textbox to equal the ID for that name (the ID column being index 0 in the table). I think the foreach part is what's throwing me off. Maybe the column stuff? My Users table is like;
ID Name
1 John
2 Roger
3 Mike

I'm having a little problem with std:fstream - in my program, the user selects the location of a file which I want to remember. So, I have something like this:
Code: std::string fileLocation;
//Code here creates an 'open file' dialog box which lets the user choose which file to open.
//The string 'fileLocation' now contains the path to the chosen file.
std::ofstream prefs("prefs.txt");
if (prefs.is_open())
{
prefs << fileLocation;
prefs.close();
}
This works fine if the file chosen is in the same directory as the program, however, if they try to choose a directory outside of where the program is kept, it saves the text file into that directory instead of the same one as the program. So, it looks like outputting a directory into an ofstream actually changes the location to which the file is saved.
Is there a way to save the file directory to a text file using ofstream and still have the text file save in the same directory as the program?

I am trying to write a program to search a library file with the name of a book or author and return the books that match the searched string in some way. For instance, if I search "Develop" it should display Game Development Essentials(Novak) and Developing Games in Java(Brackeen) and tell me that 2 records were found. Currently, it shows all the records regardless of what i search for, even if it is jibberish. Am I missing something in my functions? should I include the code that accesses these functions?
//If the user chooses A or a
int showBooksByAuthor (int count, string name)
{
char choice;
int index = 0;
}
[code]....
