C++ :: Storing Accounts In A Text File

Feb 21, 2015

The problem that occurs is coming from the I/O I believe. I am creating a bank handling program and I am storing the accounts in a <map> and then I am storing the accounts in a text file. The problem I have is when ever I am closing the application and restarting it and want to read the text file I am getting nothing or I am getting really odd results. In the application it can be that it does not read anything or it could be that I get

Acc nbr: 0
Name: -47000300
Type: 12333993
balance: Å

But in my txt file its perfectly normal. Sometimes when Ive been trying to play around with the code the txt file changes the text to kanji signs. I've created an own implemented class that handles the account for example, deposition, overloading constructor of creating an account, withdraw, returning various information. The attributes are all public.the read file function:

void read_file(){
string name;
int pnbr;
int accNbr;
int balance;

C++ :: Creating Accounts And Stores It On CSV File

Jun 20, 2013

What I am trying to do is a small program that creates accounts (User name, age,...), and stores it on a CSV file. And later I can search for a user and edit some information about him (example, his age).

Here is my code:

#include <fstream>
#include <iostream>
#include <string>
#include <stdio.h>
#include <io.h>
#include <stdlib.h>
#include <string>

Looking at the "old code" ("void searchaccountold()"), I am sure the problem is on the "while" part ("while (myfile >> name >> age >> money)").

It should work, but it doesnt. I am almost sure the problem lies on the ";"... Because the CSV uses cells, and to pass to the second cell I would normaly need an ";" and in my case I have ">>". I have tryed to change them, to use getline, etc... and didnt work.

C++ :: Bank Accounts Program Using Structures

I have an assignment to write a program using structures, getting input from a .txt file and output in text file as well. I have written a program that only reads and prints the data. I am trying to test if it works fine or not. I always comment an unnecessary code but still it wont compile. Now whats wrong with this program?

/* Bank Accounts Program */
#include <iostream>
#include <string>
#include <fstream>
#include <cstdlib>//needed to use system() function
using namespace std;
const int MAX_NUM = 50;

Visual C++ :: Moment When All Interactive User Accounts Have Been Logged Out

Nov 17, 2013

I'm writing a Windows service using WinAPIs and C++. One of the options is that I need to send the system into sleep after all users are logged out. The log-out command is started from the UI (which can notify my service), the problem is knowing how long it takes for all user accounts to be completely logged out before putting the system to sleep.

I first thought to introduce an artificial delay from the moment when the log-out command is issued and before entering the sleep mode, but in a situation when some user account was configured with a roaming profile, the log-out process may well exceed my delay.

how to know if all user accounts are logged out "for sure"?

C++ :: Reading A File And Storing It In A String

Feb 7, 2013

I know how to do this in c++ with fstream and std::string and getline and so on and so forth. Im writing my code solely in c however. I can't get g++ installed so figured it was a good excuse to learn c instead of using the equivalent c++ abstracts.

My problem is, I'm making a game in c that I have made in c++ but have ran into an issue with my map. I want to read in my map from a file which just looks like this:
Name of Town
* * * * * * *
* * * * * * *
* * * * * * *
etc...

so i tried using fscanf to first read in the name of the town (stored in a char*) then read in the characters (in this case '*')(not including white spaces becuase i can just print those) into another char*. what is the better way to do this?

C/C++ :: Reading CSV File And Storing In Variables

Mar 16, 2015

how to read a csv file where the data is seperated with commas so the csv file looks like:

programming,03,60,141,01,W,2015
programming,03,60,141,30,W,2015
Algebra,03,62,102,02,S,2013
Religion,08,98,938,20,F,2014

So i need the name of the course in one variable, the course code (ex 0360-141-01 for line 1) in another variable and the term (ie W2015 for line1). So i got the name done but cant figure out the course code since i need more than one value that is seperated by a comma. my code is:

#include<stdio.h>
#include<string.h>
typedef struct CourseInfo {
int courseID;

C++ :: Reading And Storing A Sentence From TXT File

Dec 11, 2012

I've created a class that is supposed to store first name, last name, date of birth, date of death, and a fact about a person (all variables within the class). Im trying to fill these variables with a read function. it reads a .txt file like this

Firstname Lastname 1987 1988 this guy did this

The problem is, I don't know how to handle the last variable. the variable needs to hold the entire "this guy did this" sentence. i made it a string, just because i was clueless, and as expected, it only holds "this"

this is my .h:

#include <string>
#include <fstream>
#include <iostream>
using namespace std;
class Person {
public:
Person();
Person(const Person & person);

[Code] ....

Here is the read function in the .cpp:

bool Person::Read(ifstream & input) {
return (input >> fname >> lname >> dob >> dod >> fact);
}

Visual C++ :: Reading And Storing TXT File

Feb 12, 2014

I am trying to read and store a txt file with format below:

2.5;abc;2,4000
2.5;bef;3,2000
2.5;ref;3,1000

I try the fscanf( pFile, "%d;%s;%d,%d", buffer,buffer2,buffer3,buffer4 ); to store 2.5 to buffer, abc to buffer2, 2 to buffer 3 and 4000 to buffer 4 on first line.

However, it doesn't work. How can I achieve this? I want to read the 2nd line and so on.

Code:
char buffer[100]="";
char buffer2[100]="";
char buffer3[100]="";
char buffer4[100]="";
FILE * pFile=NULL;
pFile = fopen("C: est est.txt", "r");

C++ :: Reading Data From File Then Storing It To Reuse?

Mar 27, 2013

Im tasked with reading a data file, this is an example snippet

list of trophy winners

1960/61 Tottenham Hotspur Aston Villa Tottenham Hotspur Ipswich Town
1961/62 Tottenham Hotspur Norwich City Ipswich Town Liverpool
1962/63 Manchester Utd Birmingham City Everton Stoke City

The file starts in 1892 and is up to 2011/12, there is data missing for some years due to the wars etc,

once ive read the file, i need to store the data, for me to re-use.

There are a lot of useful link regarding reading data in, but they tend to be with very small files with say 10 lines of numbers.

C++ :: Reading Integers From File And Storing Into Array?

Oct 28, 2014

My main issue is that when I store just one value into a simple integer variable, it gives me a big negative number.

My goal is to store a file that reads like this into arrays:

2014 1 23
2012 2 15
2013 1 25
etc

Where I would have the first column in an array, the second in another and the third in third array since I am not allowed to use multidimensional.

C :: Storing File Data In A Structure Of Format Shown

Aug 5, 2014

I'm having trouble reading my data from a .txt file into a structure of the format shown in my code. I've made my student database in the program below based on user input and I didn't have a problem with that, but now it's come to input from a file it's making it difficult.

My three tasks are:

(1) A table containing 1 row per student, containing the student ID number and all of the student's marks.

(2) Another table, containing 1 row per student, containing the student ID number and the average mark obtained by that student.

(3) The average mark for each subject.

The assumptions to be made are: The student ID can begin with a zero, and should therefore be read in as a string.The test data will contain 20 students but the program should be able to deal with up to 100 students.Assume there are no more than 4 different subjects.

So based on the first assumption I've arranged the data in the file in an order in which the student ID begins with a zero:

003953 Computing 38
003953 English 88
003953 Mathematics 29
003953 Physics 83
073241 Computing 63
073241 English 99
073241 Mathematics 32
073241 Physics 73

...for twenty students, 80 lines of data. Now, on the assumption they must be read in as strings, this is what's making it tricky to store in the structure because, I've got 80 ID numbers but 20 repeat themselves 4 times. Once I've got this data in the structure below the tasks I won't have a problem with because I can just base it on a user input program but the data's already stored instead.

Below is my code for user input associated with task (1). In this example the IDs are stored as ints but for the file they will be strings. It compiles fine, displays the data as shown in the assignment sheet, but I don't know how to get the data into my structure. I can store the data in a structure of three arrays using fscanf() no problem, but it's not very "workable" for what I need to do with it.

Code:

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

C++ :: Reading File With Delimiter - Storing Data To Object

Dec 5, 2014

I am trying to read a file use the data line by line to create into an object. The current file I have is like this and the code reading the file will be found below.

1223 Fake1 Name1 60 70 80 24 89 add1 Male
1224 Fake2 Name2 61 70 81 80 24 add2 Male
1225 Fake3 Name3 63 70 82 80 89 add3 Male
1226 Fake4 Name4 63 70 83 80 88 add4 Male

The problem I am having is that I need to put delimiters in the file so that a person can have more than one name and also the address can now hold multiple strings until the delimiter.

I would like to change my file to this;

1223 : Fake1 Name1 : 60 : 70 : 80 : 24 :89 : This will be address1 : Male
1224 : Fake2 Name2 : 61 : 70 : 81 : 80 :24 : This will be address2 : Male
1225 : Fake3 Name3 : 63 : 70 : 82 : 80 :89 : This will be address3 : Male
1226 : Fake4 Name4 : 63 : 70 : 83 : 80 :88 : This will be address4 : Male

How can I update the code below so that it can use the delimiters to create an object?

void loadFile(Person people[], int* i) {
ifstream infile("people2.txt");
if ( !infile.is_open()) {
// The file could not be opened
cout << "Error";
