I'm writing a program that is supposed to take text of a png file name (including the file extension) and open it so that the program can read the data inside. I'm unsure what method I can use to open the file if I just have the file name.

I have a text file called (Test.txt) with the following text:
This is line one
This is line two
This is line three
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.
I have this code for a computer project... (store management) but the character strings are not copied on text file..

Now when i run the program, it gives a error :::

How can i write these strings to the 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(){

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 need to create a program which could create text files of the bits stored in avi file/binary file. My first requirement is to show 0s and 1s in the text representation . My second requirement is to create an avi file from this text file. I have tried few codings but either they give me error or they not playing the reconverted binary files.
View 6 Replies View RelatedI 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 program I have to do that counts the number of words in a text file. I have tried the code on 2 computers now since my programming teacher told me the code was fine. Here is my code:

using namespace std;
int main() {
ifstream infile;

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.
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?
Can i edit records stored in file without rewriting whole file again .?
View 1 Replies View RelatedI just wrote a program for Huffman Encoding, where I take a text file, encode it in the form of 0's and 1's, and save that as another text file. However, this does not solve my purpose as it is taking even more space.
So I want to know how do I convert a text file containing these 0'S & 1's to a binary format.
Here is my program:
#include <stdio.h>
#include <string.h>
#include<fstream>
#include<string>
#include<iostream>
using namespace std;
typedef struct node_t {
struct node_t *left, *right;
int freq;
char c;

C++ code that will take the existing comments from a arbitrary C file, and store those files in a text document?
View 4 Replies View RelatedI want to convert a text file into binary file. I should create the text file by myself. I also use a structure for the components:
struct Data
{
int num;
char name[30];
};
I write information in the text file like this:
Data d;
cin >> d.num >> d.name;
fstream file("Name.txt");
file << d.num << d.name << '
';
If I have entered:
3 Steve
is easy to get this data. I just make another variables and get the data in them:
int num2;
char name2[30];
file >> num2 >> name2;
And everything is done. But what if I have this:
cin >> d.num;
cin.getline(d.name, 100);
file << d.num << d.name;
and the input is:
5 Steve Brown
I can get the number easy like before but how can I get the whole name? If I use:
int num2;
file >> num2;
char a[30];
file >> a;
I get only the first name "Steve". Can I get somehow and the second name in the same variable?
getting hex from a text file and writing it to a different file. I made a program to dump hex from files into a text file and now I need it to save the hex to the original file. Here is my code to save the hex:
int main(int argc, char * argv[]) {
ofstream myFile;
ifstream file(argv[1], ios::in);
[Code].....
It never outputs the correct contents of the file that has been dumped. I've checked with other hex editors and the hex dumper is working correctly.
I'm trying to make a program that you input your login info and it writes that info to a text file. Then, later on once I get my problem fixed, the program will read the info to the user. my code is as follows(the input part is a bit lengthy):
// Password Log
#include <iostream.h>
#include <fstream.h>
#include <string>
#include <time.h>
using namespace std;
ofstream login;
[Code] ....
What my problem is when I choose "Input new login info" it automatically inputs I have no clue, and calls next program.
