C++ :: Data File Handling Error - Character Strings Not Copied On Text File
Nov 24, 2013I have this code for a computer project... (store management) but the character strings are not copied on text file..
#include<iostream.h>
#include<conio.h>
#include<fstream.h>
class Store {
public:
char *item_name[5];
store()
[Code] .....
Now when i run the program, it gives a error :::
ERROR
address 0x0
How can i write these strings to the text file?
C/C++ :: Pass Path In File Handling To Create Or Open A File?
Jul 14, 2012I have a folder "pics" in g: drive. There I want to create some text.txt file. Thus, the final path is "g:pics ext.txt".
How can I do that?
C++ :: File Handling - Program To Read Inputs In TXT File
Mar 26, 2013I've written a program to read inputs in a text file. The file named Input.txt contain integers 2 3 and 4. My program is as follows:
#include<iostream>
#include<cstdlib>
#include<fstream>
using namespace std;
int main (){
int x,y,z;
[Code] ....
the program is outputing x=2293616 , y=0 and z=0 instead of x=2, y=3 and z=4.
C :: File Handling Sorting
Mar 6, 2015I am accepting the word from user and arranging it in ascending order like in dictionary in a file . I am doing this by comparing the user entered word from existing word in the file . All the word which is smaller then user entered word is copied to another file "temp.txt" , then the user word is printed and then the remaining word ( which are larger) from "abc.txt" to "temp.txt" . But program close as soon as i enter the second word
Code:
#include<stdio.h>
#include<string.h>
main() {
FILE *fp,*ft ;
fp = fopen("abc.txt","r+");
ft = fopen("temp.txt","r+");
[Code]....
Both file are already created before /
C :: WAV File Handling And Filtering
Dec 29, 2013I got this issue to tackle which consists of using an FIR LPF filter to filter a wav file using C programming.
Till now I managed to tackle the filter part following this link: Implementation of FIR Filtering in C (Part 1) | Shawn's DSP Tutorials (I have my own filter co-efficients which have been produced using FDAtool on MATLAB and some other minor changes have been applied to match my requirements)
Now, the link shown does not compensate for files having a header. I have three wav files which need to be filtered. Thus I need to first extract the data from the header .. this was done using RIFFpad. Now that I have the data
Info from RIFFpad:
fmt -
Offset=20
ID=fmt
[Code].....
I've got this hint to start with: Each audio datasample inside the wav_files can be made up of a number of bytes and these bytes arestored in the little-endian order. Inside your program you have to change this to a big-endian order.
C :: Using File Handling With Tree
Apr 8, 2014I'm given a project in college to use trees(AVL tree, to be specific) and file handling(not very conversant with it). But I'm not able to relate the two.
I only know that files can be used to store data. But in what way can trees and file handling be connected? I know how to implement trees but how to store it as such in files?
C++ :: File Handling Vs Shared Memory?
May 27, 2014In interprocess communication(IPC) when processe have to share data among each other,why cant they all connect to one single file and share data with basic file handling functions such as read and write?
Why do we need
shared memory(shmget shmat(),shmdt()..etc)
and
mapped memory(mmap(),munmap()..etc)
concepts?
C++ :: File Handling Inside A While Loop?
Aug 5, 2013I have two files like original.txt and replace.txt which has equal nbr of lines in both of them.
I need to loop through these two files line by line and replace the line in original.txt to the line in replace.txt
eg :
output.txt :
1|raj|65.4|Y|
1|ramesh|65.4|Y|
replace.txt :
1|raj|65.4|Y|
Cannot be processed|1|ramesh|65.4|Y|
What I need here is when reading of output.txt reaches second line of file "1|ramesh|65.4|Y|", it has to be replaced with the second line in replace.txt "Cannot be processed|1|ramesh|65.4|Y|".
1|ramesh|65.4|Y| --> Cannot be processed|1|ramesh|65.4|Y|
After the end of loop the contents of two files should be like :
original.txt :
1|raj|65.4|Y|
Cannot be processed|1|ramesh|65.4|Y|
replace.txt :
1|raj|65.4|Y|
Cannot be processed|1|ramesh|65.4|Y|
The files can have variable number of lines but both will have same number of lines each.

C/C++ :: Error Handling For File Opening And Reading
Apr 23, 2014I am writing to write a program and performs the following tasks
- Reading a file (txt file contains some temperature values)
- Display the temperature values (contents of the file)
- Calculating the average of the temperature values in the file.
- finds the maximum and minim value of temperature in the file.
The program is user interactive and waits for the user input and process according to his input (choice)
I have managed to complete the program and covered all the expect except the error handling for file opening and reading, although I have managed to do it for the part one part (i.e for the choice == 1)
I can repeat it for the other choices (i.e for 2, 3 ) but I do not want to repeat the code and do it in a different function or do it once for all. While making an attempt I can not handle the rest of the program and all the program turns into a mess.
#include <iostream>
#include <fstream>
#include <iomanip>
int menu();
int myChoice(char);
char inputValidating();
[Code] .....
Need Error handling for file opening and Reading that is used once, So far I have managed to do it for choice 1

C++ :: I/O Text File Handling And Dynamic Memory Allocation
May 19, 2014I am working on an OOP assignment (text handler) which part of its description is:
Some lines of text as a story which the delimiter between each story is %%%%%
Each text loaded should only occupy the space needed for the text to fit.
It's required to use dynamic variables of type char*. To be more detailed, the text-handler must contain a vector of such char-pointers (i.e. c-strings), and the parameter in the constructor indicates how many pointers (c-strings) to be contained in the vector. Each loaded text will be represented by a number, so that the first text in the file gets number 0 and the next one gets number 1 ... etc. When you want to access a text, you request the text with a certain number, and then get a pointer in return that may be used to output the text on the screen.
My problem is first to allocate a dynamic memory like char** without defining the number of array elements (Each text loaded should only occupy the space needed for the text to fit. )and then store each story from text file (comprise of a few lines of text) into that dynamically located memory(char **)to be able to do some operation on it later.

C++ :: How Exception Handling Works
Oct 25, 2014I know how exception handling works, but how should I actually use it in action? Let's say I have something like this:
Class X

//Pre-condition: example can't be 3.
void number(int example);

If I know that the exception can only happen at the beginning of the function, is it okay to catch it right away?

Visual C++ :: Handling CDialogs In MFC App?
Apr 12, 2013I have a MFC app developed in VS 6.0
User can open multiple dialogs in this app. Is there a way of keeping track of how many dialogs are open at a given time?
Also, is there a way of getting the handle to each dialog from a central location?
Because the dialogs are opened from different parts of the app, i.e., different files its hard to keep track of all dialogs.
C++ :: Handling Multiple Connections?

My Questions
1. What these lines is doing
Code:
newsockfd = accept(m_sockfd, (struct sockaddr*) &cli_addr, &clilen);
Code:
close(m_sockfd);
Code:
close(newsockfd);
2. And why there is no create(), connect(), read(), write() methods for client
C++ :: Handling More Than One Exception At A Time
Feb 12, 2015It is advisable not to throw the exception from destructor. Because if exception happens stack unwinding happens. suppose the destructor again throws the exception then on part of first exception again one exception is thrown and exceptions can not be handled at same time. This is what i read from stack over flow.

C :: Pages Handling In Embedded Source
Jul 9, 2013I'ma firmware writing, and usually use only C language (not my decision, unfortunately!).In many application we've only a text display (2 rows 16 columns ascii char, or 4x20 or something else). But the question can be used also for semi graphics panel and so on.
I'm looking for an example / library / sourcecode to handling all the pages in the project. When the program start you've a 1st page (wth info abt release, hallo screen and so on), then with a arrows buttons you can navigate throught many pages. Some of these can be called by SW (or HW) events. (Button, alarm, end of job ...) In abt 20 year of experience3 I?ve seen many type of different code.
