Is it possible to display data from a textfile and also save data in to a textfile, reason being is for me to create back-ups of data into a textfile hidden somewhere in a safe location in the local disk or server in case of database error and failure.
View 3 RepliesSo I'm really stuck trying to figured this bug on the program that is preventing me from displaying the text of my program..
#include <iostream>

I'm working on a program that can load all words from a dictionary "English2.txt" (it's attached to the post), then put every word into a 2-dimensional matrix (every line is reserved for one word) and display them. After loading every word into a matrix, when I try to display first 8 words with printf, I can't do it without '' at the end of a line. Otherwise only the 8th word is displayed... What's more, when I try to read the length of the first word with strlen, it says, that it has 4 characters (in fact there are only 3 and it's the word "AAA"). What could be the reason for that?
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdint.h>
int main()
{
FILE *fp;
char buffer[32];

My application requires the user to add sales to images, this is done by displaying the image for the GUI, and then the user would add sales using that images ID which is brought in from the database.
In part this is 2 questions, first question is what is the best way to generate a List for use when adding the sales to the database. The List would need multiple strings for each sale. So for example:
Image 1 (Sale)
- JPG ID
- Product ID
- Product Quantity
So i'm going to assume i'm best creating a new instance of a custom class for each sale, and then add each instance to a List<Sale>?
public class Sale
{
public int SaleID { get; set; }
public int JpgID { get; set; }
public int SaleQty { get; set; }
}
Then I need a decent way to update this List with the GUI controls. So maybe get the JPG ID and set name of the Sale Class Instance to the ID, in this way its unique and I can update that instance when it comes to increasing the sale of a product or decreasing it.
Second part comes to the design of the GUI of adding sales, when I made this using HTML/PHP that was easier. It looked something like this:
If I wrote some code to generate that kind of design again in C# it going to require many Controls, wouldn't that be a bit intensive on the system? I just want something which looks great but also functions good.
At some point I'm going to switch to WPF, but I just need to get a working prototype working now which my client can use, and then update it when I have more time as I have got other Web Related projects that need doing, so at the moment WPF is out of the question.
I've been trying to write my homework assignment (a list of countries, their codes and their capitals) and I've done most of it but I'm stuck at this: I have to open a file, read it and if there are data, add them to the list. So far I've created an element of the structure, queue list, printed the list on the screen and freed the memory. I thought that for reading the file and adding the data I could first open the file (of course) with fopen and after that use a for loop (i=0;i=!EOF;i++) to scan the whole file and fscanf(fp,"%s",result->country),etc in the loop to add the data to the structure of the element and finally insert that element to the queue list. However, when I try to do these operations, I only get to writing the name of the file and the program crashes.
Code:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
struct List {
char country[20];
char code[5];
char capital[20];
struct List*next;

I have a text file that is divided into blocks:
#1
1:animal
2:food
3:moves
4:oxygen
#2
1:eats:2
2:breaths:2
3:can:1
4:is a:1
#3
1:1:2
1:3:3
1:2:4
And the following program that displays block by block:
StreamReader streamReader = new StreamReader("G:LAB123LABWORK2.txt");
int block = 0;
while (!streamReader.EndOfStream) {
string line = streamReader.ReadLine().Trim();
if (line.CompareTo("") == 0)

My problem is am supposed to add a verification code so that if i put a string e.g 1:?:? it returns the block where the string is found and gives of all possible answers.

I'm making a very first program. It's very little more then a simplistic calculator, but i'm having a problem with the cout function. It won't display any text what could the reasons be?
#include <iostream>

#include <sstream>
using namespacestd;
int main () {
do {
int(a);

Oh and i'm aware it's still riddled with numerous problems, I just have been working on the cout thing first.
I wanna read data from txt file with space divided each value like

I know the size of the data is 2*500.
In matlab I can use like
fid = fopen('example.txt');
data = fscanf(fid,'%f,',1499500);
how should I write in C++?
I need to copy data from one text file to another.This is how data in file looks like:
2 -3 8 5 0
3 5 1
2 -2 3 1 7 6
5 -3 15 0 1
I succesfully managed to copy those numbers but with one mistake.The last number is written twice. My output file looks like this:
2 -3 8 5 0
3 5 1
2 -2 3 1 7 6
5 -3 15 0 1 1
This is my code:
int a;

read some information from a text file. The program I'm working on is like a simple betting program.
What I need to read are:
match_code - team1 - team2 - odd1 - odd0 - odd2
139 Atletico Madrid - Real Madrid 2.853.40 2.35
But the spaces between datas are not known. We only know that both team names may contain more than one word and there is one space, exactly one dash and one more space (" – ") between team names.
Also match_code is an int and odds are double values.
while(getline(input, line)) {
istringstream ss(line);
ss >> match_code >> team1;
string temp;
while(ss >> temp) {
[Code] .....
In that missing part, I need to get the second word of team name if there is one; and the three odds that are odd1 odd0 and odd2.
Each line of the text file has first name, last name, and a salary. Something along the lines of this:
john doe 4000
bob miller 9000
I want my program to take the first name, last name, and salary of each line and assign them to strings. I have tried this so far:
while (inFile){
inFile >> firstName;
inFile >> lastName;
inFile >> grossPay;
cout << firstName << " " << lastName << " " << grossPay << endl;
}
When it outputs the names and the salary, the last line of the text file gets output twice by the program.
Requirements in filtering the text file.
1. first my professor required me NOT to change the MAIN function(because he made it)
2. I have to make 3 getlogs() STRING FUNCTIONS:
a. string getlogs(); - accepts no paramters, SHOWS ALL THE CONTENTS OF TEXT FILE
b. string getLogs(const string & a); - accepts 1 parameter -SHOWS ONLY THE LINE WHICH CONTAINS THE SPECIFIED DATE FROM MAIN FUNCTION which is "2014-08-01"
c. string getLogs(const string & b, const string & c); - accepts 2 parameters, SHOWS ONLY THE LINES FROM THE DATE START to DATE END specified at THE MAIN FUNCTION which is date start-"2014-08-01";DateEnd = "2014-08-10";
3. all COUT should be in the MAIN FUNCTION
TEXTFILE CONTAINS:
2014-08-01 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-02 06:13:14,Name,4.5,CustomUnit,CustomType

How to get a txt Outfile to display a Checksum.
Code:
ChecksumFileDisplay = fopen(ChecksumFileDisplayPath, "r");
fprintf(ChecksumFileDisplay, BigEndianChecksum);
That's what I have but it doesn't like the fprintf function because BigEndianChecksum is an unsigned int and it wants a pointer to a const char. Is there a function similar to this that will display an 8 digit integer in a txt outfile?
Provide three menu options to format the text entered in QTextEdit to
(1) display the letters in capital letters
(2) display the text in red
(3) align the text in the center
I did the 2nd and the 3rd part but I can't find the capital letter part
Code:
if (name == "Color") {
textEdit->setTextColor("red");
}
if (name == "Capital") {
textEdit->??????;
}
if (name == "Center") {
textEdit->setAlignment(Qt::AlignHCenter);
}
I'm still learning intro to C language. Currently I'm having problem with my code. The task is to ask user to input information about staff and write them into a text file. The problem occur when:
1) output in text/.exe file display random characters.
2) Data obtained from New_Staff unable to pass into Export_Profile.
3) a new output will overwrite the existing information in the text/.exe file
4) the delete function unable to delete correctly after the first time i delete a staff information in text file.
The code is as follows:
#include <stdio.h>
#include <stdlib.h>
void Menu();
void New_Staff();
void Delete_Staff();
void Export_Profile();

& Also how to read data from this file.
I have a program that saves all information temporarily into memory (into the array), however, I need a permanent save solution. I have the full program working correctly, formatted perfectly, but it's missing the file array to file output.
Essentially, whenever I'm presented with the menu I'll be able to add entries, search by last name, show the entire list, and exit and save. Whenever I select option 4 the program should save to a file "address_book.txt". Whenever I reload the program, it should load from "address_book.txt" and populate the array with the preexisting data.
My question is focused on how and where I should implement the file output. What I have thus far:
#include <iostream>
#include <string.h> //Required to use string compare
#include <fstream> //Eventually used to store array into file
using namespace std;

I am currently working on a project that requires me to "load the data in the file into array at the beginning of the program."
I have a text file with data, and I need to populate an array with the information. From then on, I am supposed to be able to add, display, and search that array. However, I can't figure out how to add the data from the file into an array. I was trying to find out how to search the text file itself. So it threw me off balance and I've been staring so long at the screen I can't really focus.
I am trying to read an array values from Tmin.txt file. I take array size from user viz. number of raw & column and then, read the following data from Tmin.txt file which look like this:
20 40 20 25 30
20 30 40 20 25
20 40 20 25 30
20 30 40 20 25
30 40 40 30 40
I am using getline, and then converting it to int by using atoi. But my code is not working.
