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
this is my C# code
System.IO.Directory.SetCurrentDirectory
("C:/Users/fahime/Documents/Visual Studio 2010/WebSites/MyWebSite/UserFiles/ProblemAnswers/");
Process.Start("cmd.exe", @"/k ""C:Program Files (x86)Microsoft Visual Studio 10.0VCvcvarsall.bat"" x86");

I want to compile my cpp code file with visual studio cmd
I am facing a problem in C++,I want to execute a command in Command prompt from a specific path.I am able o select a path and execute cmd.exe using the function ShellExecute but the problem is after selecting the path I am not able to execute the command, the command is appearing on another command prompt.

./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();

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.
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;

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
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

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.
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[] ?
I need to write a ANSI program to print out each command line argument on a separate line using a for-loop. also it need to print the name of the executable .so far I have

int i;
printf("")

l need to write a program which writes out its command line arguments in reverse order one per line. The output from the program should look like this:

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.
I am using visual studio 2010 c++ express for C/C++ programming but is novice here to take command line arguments..i did went to project->properties->debugging and specified there the command line arguments but it didnt work..i think i need to know the format to enter the arguments.

I am writing a c++ program in Linux.. I am reading a line from commandline at run time using "getline(std::cin,str);". now, what i want is if i left the commandline as idle (terminal as idle), then i want to know that the commandline is empty... is it possible ???

When you write and compile a program, on the right side (the "output" side), you can read this command line arguments:
$ g++ main.cpp -o demo -lm -pthread -lgmpxx -lreadline 2>&1
What is the meaning of the following arguments? -lm [link the math header file, right?]
-pthread
-lgmpxx
-lreadline
Any book (ebook, tutorial, printed book, whatever) where I can find all (absolutely all) these and other possible arguments?
I tried the exercise 5 on page 312 of King's Book C programming A modern approach second edition. Write a program named sum.c that adds up its command line arguments which are assumed to be integers . Running the program by typing :
sum 8 24 62 should produce the following input
Total : 94
Use the atoi function to convert each command line argument from string form to integer form
My solution is :
Code:
#include<stdio.h>
#include<stdlib.h>
int main(int argc , char *argv[])
{
int i , sum=0;
}
[code]...
It is running good without problems but I am wondering because it is very small solution with few lines of code.
I want to see how the command line arguments work. However I don't know how to enter this input. show me a method to see if my code works?
View 9 Replies View RelatedI have to make a c++ program, in which with an algorithm I have to code a text from a file and write it to another file. The input should like this: "code forCoding.txt toBeWritten.txt" ; or like this: "decode toBeReadFor.txt toBeWrittenIn". I have done everything except one thig: It is says I have to be able to input parameter.
How should i write this? I read [URL] ....., but still dont get. The input of my program has to have 3 strings, so I guess argc should be 3, but I dont really get it. What should I have in my main about this parsing command line parameters?
I am not sure how to enter command line arguments when I run the executable of the file below. I want check an make sure that only two arguments get into the main() before running the rest of the code. I'm using bash on linux.
An example that I have tried to test for 2 arguments in command line -arg1 arg2 > ./a.out This of course does not work
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>

I know you go the the debugger and pass them in. I just need to know the syntax. I know &(ProjectDir) goes first because the text file is in the project directory but how do I pass the text file in as well. The file's name is "tester.txt".
View 2 Replies View RelatedI know this works as expected if your command line arguments are strings.
#include <stdio.h>
int main( int argc, char *argv[] ) {
printf("Program name %s

if( argc == 2 ) {
printf("The argument supplied is %s

Would you be able to do something similar to this if you have integers or would you need to use the first method then convert it with atoi?
#include <stdio.h>
int main( int argc, int *argv[] ) {
printf("Program name %s
", argv[0]);
if( argc == 2 ) {

I have "hello world" set for command line args.
int main(int argc, char **argv) {

Why would it do that.
