I use this header dirent.h to get list of files in directory
[URL] .....
I am using code::blocks on windows XP.
Directory "kernels_source" is placed in project's directory where I am running the code.

#include "include/types.h"
#include "include/gaussian.h"
#include <stdio.h>

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 tried listing files using the code given in "[URL] ..." the program listed all the files present in the current dirctory but if i change the drive and the directory to such as
"C:UsersBaaooDownloadsdirect.h function"
the program does not list files name.
#include <iostream>
#include <dirent.h>
using namespace std;
int main() {
DIR* dir;
dirent* pdir;

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];
static std::stack<TCHAR*> directories;
[Code] .....
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

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:

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?

How can i resolve this?

View 3 Replies View RelatedI am trying to compile some code under opensuse 12.2. The code compiles fine under cygwin and CentOS. Under suse, I get the error "directory name must immediately follow -I"
This is the place in make where the error happens.
Code:
g77-3.3 -I ./src/src_common_depend/ -O2 -DVERNUM=6 -c -o bld_dir/FortranA.o src/src_client_main/FortranA.FOR
f771: error: directory name must immediately follow -I
The includes are specified in the make file with,
SOURCELOC = ./src
INCLUDES = -I ${SOURCELOC}/src_common_depend/
These are common includes that are used by more than one applications and so are stored in a common location.
I have tried leaving off the ./ and the trailing /
SOURCELOC = src
INCLUDES = -I ${SOURCELOC}/src_common_depend
And various similar combinations, including parenthesis instead of the curly braces.
I'm not sure why gcc under suse would be particular about this syntax when gcc under other distros seem to think it's fine.
This is the compile rule that g77 is implementing where the error occurs:
# compile src fortran objects with fortran preprocessor
$(BDIR)/%.o: $(SOURCELOC)/src_client_main/%.FOR
$(FCOMP) $(FCFLAGS) $(VFLAGS) -c -o $@ $<

It has something to do with the lines at the bottom of the code. It doesnt cout anything. The program just crashes upon execution. First, it asks me the amount of students i want to handle. I enter '1'. Then it asks me if i want to read in from external file and i enter 'Y'. then the exe just crashes

I have to write a program that sorts names and grades from a file and output them to another.
For example:
Name: Peter Parker
Exam 1: 95
Exam 2: 90.625
Exam 3: 91.20
Name: Mary Smith
Exam 1: 65
Exam 2: 79.1234
Exam 3: 70.24
Becomes something like this in the output file:
Name: Parker, Peter
Average Score: 92.28
Grade: A
Name: Smith, Mary
Average Score: 71.45
Grade: C
I know I'm supposed to read the whole file, but I'm getting really confused on how to take the name of each student separately without recording Exam 1, 2, and 3. I'll be able to do the average score and grade on my own.
Is there a way to indicate how many records exist in a given file? For example, vectors have the vector.size() command to show the number of given elements. Is there a such command for files and records?
View 6 Replies View RelatedThe 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.

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;
[Code] ....
My question portion is attached. The code I have written is below.
#define _USE_MATH_DEFINES // for C++
#include <cmath>
#include <iostream>
#include <iomanip>
[Code].....
I'm messing around with reading and writing files. The first file creates a small txt file. Simple enough
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main(){
string name;
string desc;
[Code] ....
It does what it should. It creates a text file "items.txt" .... It reads as such:
dagger,a dagger,15,10,0,1,3,1,0,0,0,1,0,0,0,0,0,1
The second file is meant to read the file and place the data back into the variables. This happens, but the data crams itself into the first variable, and the rest of them collect the trash that's in memory.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
string name,desc;
[Code ....
I need to get "dagger" into name, "a dagger" into description, and each value with their perspective variable. I'm sure I need some type of "separator". Hopefully I can use the comma. Before it's over, I will have about a hundred items that will need to be read into a class of items.
My assignment was to take numbers from two different files, and merge them into a third file in numerical order. I have everything working well, but the output shows the lowest number everytime and i'm not sure why. logical error ....
Sample:
File1 File2 File3
10 12 10
20 25 12
30 37 10
40 49 25

Here is my code as well
#include <iostream>
#include <fstream>
#include <cstdlib>
using namespace std;
int main() {
ifstream File1, File2;
ofstream Output;
[Code] ....
Code:
struct magic {
char windowsheader[2];
} magicnumbers;
struct bmp {
unsigned int sizeofthefile;
short int applicationspecific1;
[Code] .....
When I run this program, seems like it is working,at least I am sure that it gives the right file size. But if I don't use struct magic and instead use:
Code:
struct bmp {
char windowsheader[2];
unsigned int sizeofthefile;
short int applicationspecific1;
short int applicationspecific2;
//same lines with above
} bitmap_header;
And if I don't use first fread:
Code:
fread(&magicnumbers,sizeof(magicnumbers),1,fp);
Then the values which structure "bmp"'s variables get become wrong. Of course I change the related printf to:
Code:
printf("
windowsheader:%d %d
",bitmap_header.windowsheader[0],bitmap_header.windowsheader[1]);
Why does the problem happen,what is the difference between them?Why do I have to use separate structs?
reading fasta formatted files. Usually ppl from computation biology know what that is but for those that are not here is a quick guide :
Fasta formatted file:
Code: >header
seqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseq
seqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseq
seqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseq
seqseqseqseqseqseqseqseqseq
>header1
seqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseqseq
seqseqseqseqseqseqseqseqseqseq
... so a very simple file format. and what i need to do is to read that into memory (vector of strings) so that header info and seq info is in two different vectors. for that i am using the following function :
Code:
sequence and headers vectors are class variables:
template <typename TStr>
template <typename FS>
void FastaSeq<TStr>::ReadFasta(FS& fs){
string line;
string seq;
while (fs >> line){
if(line.c_str()[0] == '>'){
[code].....
this code does what is suppose to do but it is EXTREMELY slow. it takes me exponentially more time to read the seq in memory then to process it. when compared to c style alternative that reads character by character it takes 13 sec with this function to do the same job that my c function does in 0.03 sec. How to improve upon this function to make it comparably fast (also i am using optimization) ?
I want my program to be able to read text files in the format:
number number
number number
number number...
and so on, so there are two columns of values. The problem I'm having is, there are a lot of numbers in the file, and it can vary. The program needs to read the numbers, put one column into one array, and the other in another, perform some operations on it all, and eventually pop out two different arrays. In other words, after I've got these arrays, I don't need them for much longer. I was hoping I could dynamically allocated some arrays to store the numbers and just free them as soon as I'm done with them.
If the file wasn't of such variable size or if it was guaranteed to be under a certain number of variables, I would have used:
Code:
while ( fscanf(input, "%lf %lf
", &col_1[], &col_2[]) == 2 )
{
no_rows++;
}
The problem is I want to allocate "no_rows" as the array size, which I don't have until after I have read the file.
