C :: Command Line And Converts String From File Into A Linked List

Jul 10, 2013

My program takes in an input file from the command line and converts the string from the file into a linked list and then depending on the command it will manipulate the string to either reverse the list, print the list, or take a character out...I'm having trouble taking a character out, my code compiles fine but doesn't change the string at all

Code:

#include <stdio.h>
#include <stdlib.h>
#define SIZE 1024

[Code]....

C++ :: Using File From Command Line

Apr 13, 2013

I'm trying to read in a file specified in the command line but I'm having some trouble. The command line entry specifies the inputfile preceded by '<' and the output file preceded by '>' like so

./program -v < input_file.cmd > output_file.cmd

This is what I've got so far.

int main(int argc,char* argv[]){
string strv="-v";
string input="<";
string output=">";
string str;
string input_file;
const char* in=input_file.c_str();

[Code] .....

This compiles ok, but when i run it using :

./program -v < test1.cmd

I get a segfault, if i cout argc it returns '2' where i would expect for this command line entry, I 'd get 4.

I'm not yet outputting to file, just to the screen so im not specifying an output file yet.

C :: Reading A File Through Command Line

Jul 11, 2013

I'm currently working on making a program that is run through a GUI run through the command line. The program basically takes an app file and a boot file and runs it through a bunch of functions and generates a new outfile. Anyway I'm new to C and can't figure out how to code it so I can type the two file paths into the command line and read them into the function. Is it possible to do this within the "if else" statement?

Code:
int main(int argc, char *argv[]){
const char * const SrcFilePath;
const char * const SRecordPath;
const char * const FopIspFilePath;

[Code] ....

C :: Compile File From Command Line To A Different Path

Jun 28, 2014

I'm working on windows and I'd like to know how to compile the C file to a different path.

What I mean is : the basic compile command is :gcc Hello.c -o Hello_E

I'd like to create the "hello_E" in a different path.Something like this:

gcc Hello.c -o C:Program FilesPellesCC_programsExe_filesHello_E

C++ :: Reading Contents Of A File From Command Line

Feb 7, 2014

i would like to read the content of a text file data.txt (line by line ) directly from the command line using this command: a.exe < data.txt.

What could be the c++ code to read/get the content of these lines (without using ifstream). The treatment of the lines is not a problem for me but i really don't know how to access the content of the file from the c++ code

C++ :: Program To Search Index File Using Command Line In Linux

Oct 28, 2014

I have code that creates an index file created from a data file of records.

#include <iostream>
#include <fstream>
#include <map>
#include <sstream>
#include <string>
#include <iomanip>
using namespace std;
class Record {

[Code]...

I now need to write a second program that allows the user to enter a command on the Linux command line such as

search 12382 prog5.idx

and returns the information for the record with that key. The code I included for the index file is correct and works properly, but how to write the second program.

Here is the index file created by the first program:

8: blank 0 $ 0.00
12165: Item16 30 $ 7.69
12345: Item06 45 $ 14.20
12382: Item09 62 $ 41.37
12434: Item04 21 $ 17.30
16541: Item12 21 $ 9.99
21212: Itme31 19 $ 8.35
34186: Item25 18 $ 17.75
41742: Item14 55 $ 12.36

The top line is a dummy record, the first number is the size of the file.

Visual C++ :: Enter File Name By Keyboard Instead Of Command Line Arguments?

Mar 10, 2013

Actually the below program is for Dispersal Algorithm called Rabin-IDA; this algorithm divided the data into N pieces and then recombine it from M pieces (such that M<N).

Thus, the below program needs command line arguments,which entering by Project properties/Debugging. this argument is file name, where the program performing spitted the file into N files, and then recombine it from M divided files, and put it on another file which should also passing its name as argument .

Now my question is, How can i make this program enter the file name by keyboard??(i mean enter the files name by user from screen not as command line arguments) ... In another word, How I can exchange ?

Code:
argc == 3
and
Code:
argc == 2

To enter file name ? i mean what i should do to in

Code:
rabin.split(argv[1])

To pass my file name by use keyboard not Project properties/Debugging?)

the below code is just the main function of program, and the whole of it in this link [URL] .... Information Dispersal Algorithms Rabin-IDA.

Code:
#include "include.h"
void __cdecl _tmain(int argc, TCHAR *argv[]) {
DWORD ini=GetTickCount();
try {
if( argc == 3 ) //recombine

[Code] ....

I know I should use getline() function but how exchange argv[] ?

C :: Reading A File Line By Line And Storing It Backwards Into A List

Sep 25, 2013

So I'm reading a file line by line and storing it backwards into a list. So if the file has has this format...
1
2
3
4

The code should store each line in a list as such...
4, 3, 2 ,1

Instead the code will store the last variable in all nodes. So the final list will look like this...
4, 4, 4, 4

Here is my code...

struct node *head = NULL;
int i;
while(read(in, &i, sizeof(int)) != 0) {
struct node *temp = malloc(sizeof(*temp));
temp->line = &i;
temp->next = head;
head = temp;
}

C++ :: Read Line By Line From Text File To String

Jul 5, 2013

I have a text file (test.txt) with the following data:

01,05,25,20130728
01,06,25,20130728
01,07,25,20130728
01,08,25,20130728
01,05,25,20130728

01,05,35,20130728
01,05,25,20130728
01,05,35,20130728

I want to read this to one string called line. So far I have this code:

string line;
ifstream myfile ("/home/Test.txt");
if (myfile.is_open()) {
while (myfile.good()) {
getline (myfile, line);
for (int a = 0; a <= 335; a++) {
cout <<line.at(a);
} }
myfile.close();
}

so far its only printing the first line and then throwing an instance of 'std::out_of_range'

C++ :: String Operation While Reading Line By Line From A File

May 12, 2014

I have to read the information about logic gates from a file. The file format is shown below:

Code:
gateOne = NAND(inpA, inpB)
gate2=NAND(1,2)
3 = NAND(23,25,26)

As, it can be seen from the above structure that whitespaces are not same everytime. So, to deal with this situation, i am using boost library to remove all whitespaces from the line which is being read and then try to find the name of gate and its input. My code is given below which is able to correctly find the gate names and its first input...but my code is not able to find the second, third and so on input names.

Code:
//C
#include <stdio.h>
//C++
#include <iostream>
#include <sstream>
#include <fstream>
#include <string>
#include <cstring>
#include <boost/algorithm/string/erase.hpp>

C++ :: Get Last Line Displayed By Another Command Line Window

Apr 14, 2013

I write a program which now works perfectly well. However, I want to make it run at the right time automatically, instead of waiting for a user to start it when needed.

The basic problem is, that in a WinPE environment an exe is running. Unfortunately it would need critical input, which must be inputted perfectly. So, I wrote a program which gets the data and sends it to the other app, by bringing it to the front and presses the keys needed using SendInput().

However, this program should wait for it's cue, then get on the inputting part. It's cue should be the point where the program waits for the first user input with this displayed on the last line:

Text:

My question is: how to listen and check whether the last line displayed is "Text:"?

I've tried with AttachConsole(), but for some reason it opens a new console window. I checked and the PID I'm using is the console window's, so I don't know why that happens.

The few lines I'm trying with:

HWND hwnd = FindWindow(NULL, "Administrator: Command Prompt");
SetForegroundWindow(hwnd);
SetFocus(hwnd);
DWORD process_id;
GetWindowThreadProcessId(hwnd, &process_id);

[Code] ...

Please don't criticize the first line. I know it can be ambiguous, but I modified it, When actually using it, the exe name will be in the title, so it will be unique.

C# :: Linked List Storing String Values

Apr 8, 2015

I am creating a to-do list application and to store the tasks on the list, I am trying to create a linked list. the code for it so far is as follows:

public class Node //Class for nodes which make up a linked list {
//Declaring the data to be stored in each node and next variable to point to the next node
public string title;
public string description;
public string priority;
public string finish;
public string complete;

[Code] ....

The problem with this arises when I try to create a new node from another class like so:

createForm create = new createForm(); //Creates an object reference to createForm
create.ShowDialog(); //Shows the createTask form for creating a new task
//Declares variables and stores the return value of methods in createForm
string _title = create.getTitle;

[Code] ....

The variables _title etc.. all store values from text boxes as string. However, the code creating the object says the the variables cannot be implicitly converted from type 'string' to 'int'. Why this error is happening??

C++ :: Strcmp On Linked List Data And String Constants?

Sep 28, 2013

why strcmp() doesn't return true when comparing a string constant with a string that was acquired via a linked list. By the way, the data in the linked list was taken from a text file. Does that imply that there's a new line () character in the string from the linked list?

Code:
struct Node{
char ACNO[15];
struct Node *next;
