C :: Merging All TXT Files In A Directory
Dec 6, 2013
I'm writing a program to merge all .txt files in a directory. I had the code working and then made small change. It started crashing and I couldn't get it back to working.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <dirent.h>
#include <unistd.h>
#include <string.h>
#include <sys/stat.h>
[Code] ....
It's crashing around the
Code: while(!feof(in)){ .
If I comment that section out, the code still works. But, I know that portion of the code works to copy text from one file to another! It's actually from the Schildt complete C reference and I have tested it several times on it's own.

I have come up with code for this, but am currently having issues finalizing it. It seems that it only puts out some of the numbers in a numerical order, but not all from both text files.
#include <iostream>
#include <fstream>
#include <cmath>

i need to write a c++ code which can merge contents of several .txt files into a single file. i used the following code , it works but after merging the result file contains the contents merged twice.I think it over writes the result.I want to do it without using command line.
#include<iostream>
#include<fstream>
using namespace std;
int main()
{
std::ofstream("merge.txt");
system("type *.txt >> merge.txt");
system("pause");
return 0;
}

The directions are to write a program that reads sorted integers from two separate files and merge the contents of the file to an output file (third file). The only standard output will be any errors to be reported and a “FINISHED” statement after all items have been processed.
file1.txt
2
4
6
8
10
file2.txt
1
5
11
12
15
Output.txt
1
2
4
5
6
8
10
11
12
15
This is the code I have so far, but it is not working, and I have put the two txt files in the same directory as my .cpp file. It is not working though still. What have I done wrong and how can I fix it to read these integers from the two numbers and merge the contents into a third file?
#include <iostream>
#include <fstream>
using namespace std;
int main() {
int num1;
int num2;
ifstream inputFile;

I'm trying to merge two files, The Adpoted.txt, and The Originals.txt, into one file, The Big Picture.txt. I'm compiling and getting an insane amount of errors, and am not even sure where to start with them :(. I'm getting errors for lines that don't exist. I suppose I should start with those that do!
#include <iostream>
#include <fstream>
#include <cstdlib>
using namespace std;
#define theAdopted "The Adopted.txt" //His family
#define theOriginals "The Originals.txt" //Her family
#define theBigPicture "The Big Picture.txt" //Our family
int merge(ifstream&, ifstream&, ofstream&);

Write a program that opens two text files (input1.txt and input2.txt) for input and one for output (output.txt). The program should merge the two input files in the output files. While doing the merge, it will read one line from input1.txt and one line from input2.txt and write those in the output file one after other. Then it will read the next line from input1.txt and next line from input2.txt and write them one after other in the output file.
This is my code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
ofstream myproject;
myproject.open("input1.txt");
[Code] .....
I need to:
1. how to get the second line in the input1.txt file and so on.
2. After the writing in output.txt, count the number of lines in output.txt.
3. write the number of times term ‘line’ appears in output.txt file.

I'm having an issue with merging two files. Basically, my instructor gave me pseudocode and two files to merge together. Each file (a male client and a female client file) has three names and id numbers inside. The finished MergedClients.rtf should have all six clients in ascending ID order. I wrote the C++ code and after combing through a couple times to fix a few errors, it finally ran. The problem is it starts the process, but it doesn't ever finish.
I tried changing some of the bool expressions thinking I mixed up the true and false parts. After that the program ran and it created the new output file, but the file was empty. So, I don't think I mixed any of those expressions after all.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main(){
ifstream inFile1;
ifstream inFile2;

I'm learning to merge files, but I think I'm getting it all wrong.I'm trying to merge two .txt files, and have them alphabetized on the output file. I'm getting a couple of error codes that I'm not sure of.
These are my errors:
Quote
73 no match for 'operator>' in '(&line)->std::basic_string<_CharT, _Traits, _Alloc>::operator[] [with _CharT = char, _Traits = std::char_traits<char>, _Alloc = std::allocator<char>](((unsigned int)k)) > nTemp'
77 cannot convert `std::string' to `char' in assignment

I'm using the following code to capture all files in a directory - but when I pass the "path" var such as "C:SomeDir" ffd.cFileName is just simply "SomeDir" and is seen as a valid folder and no more files are processed.. I'm trying to get the contents in that folder. I'm following this example here - [URL] .....
Code:
bool ListFiles(TCHAR* path) {
HANDLE hFind = INVALID_HANDLE_VALUE;
WIN32_FIND_DATA ffd;
TCHAR * spec = new TCHAR[_MAX_PATH];

I'm trying to output only a few files, using regex, from the current directory, this is my main code:
Code:
// main.cpp
{
char * _dir = new char[MAX_PATH];
getcwd(_dir, MAX_PATH);
unique_ptr<CExtractor> _ptr(new CExtractor(_dir));
delete[] _dir;
}
Code:
// CExtractor.cpp
DIR *pdir = NULL;
struct dirent *pent = NULL;
pdir = opendir(_cwd.c_str());
while ((pent = readdir(pdir)) && (pent->d_type != DT_DIR)) {
if (regex_match(pent->d_name, regex(".(in|txt)$"), std::regex_constants::icase)) {
cout << pent->d_name << endl;
}
}
closedir(pdir);
My code is compiled correctly, but when I run my binary, nothings is outputed..here are my files in the current directpory:
aclocal.m4 config.guess config.status depcomp m4 NEWS
AUTHORS config.h config.sub INSTALL Makefile README
autom4te.cache config.h.in configure install-sh Makefile.am src
ChangeLog config.h.in~ configure.ac libtool Makefile.in stamp-h1
compile config.log COPYING ltmain.sh missing
I have a few "in" files

write a code using vs studio 8 to read a diretory name as argument and then open the directory and read each file one at a time and find the match for a string passed as an nother argument in the lines of each file. When it matches create a file and write in that output file the file name whetre the match found, the line number and line which matched.
My vis does not have dirent.h. so please use another ways to read directory call witha system acll and then then extract the fienames in a file(use some primitive way to open the the directory)
I cant do this parts
(1) read a directory
(2) create a file with only file names
(3) read file names ans open the files one at a time till the end of the file reached

I've tried to form together the following code so that I can process multiple files from one user specified directory. However, when I run the program it works great for the first file, but all other files are blank. The problem starts on the following line:
while(FileIn.good())
//---------------------------------------------------
#include <fstream>
#include <iostream>

I need to write a program that acts as a file manager for all the files and folders in the directory given as an argv parameter and all of its subdirectories. This means be able to move, rename, delete the files in the sub directories. Also I need to be able to store the structure of folders and files in a binary tree adt (I have one already). But I'm not sure what libraries to use with this and how do I open a directory is it like a file with fopen?

i've just started learning building structures in c++ and they gave us an exercise of writing a recursive merge code of linked lists - just merging without sorting... i don't even know how to start this is how i started so far.... i know that the break in the recursive function is when i get to the end of the first list and then to start linking the second list..as you can see i wrote a function that uses recursive function...
LIST merge3(LIST lst1, LIST lst2) {
LNODE* curr1 = lst1.head;
LNODE* curr2 = lst1.head;
LIST mergeList;
mergeList.head = NULL;
mergeList.tail = NULL;

I have two std::sets S1 and S2 which I need to merge.
I know that the largest element of S1 is less than the smallest element of S2.
the additional information about S1 and S2 should enable me to do the insertion of each element in costant time instead of log(N).
what is the fastest way to calculate the union of the two sets?

I am having to write a program that takes 2 sorted linked lists (x and y) and merge those to sorted into a third one (z). This has to be done via recursion. I think I am close but there is a logic error.
Code:
void SortedMergeRecur(Node*& xHead,Node*& yHead,Node*& zHead)
{Node* temp = 0;
if(xHead == 0) {
zHead = yHead;
yHead = 0;
}
