C++ :: Input Txt File Using Cmd Line Arguments

Apr 9, 2012

I am trying to use the command line to put a txt file in this code. I do Project->set project arguments in code blocks and nothing happens. How does one set up the arguments and where do i do it in codeblocks?

Code:

int main(int argc, char *argv[]) {
char name[20];
struct artist *ptr;
char lineBuffer[LINEBUFFERSIZE];
artistNodePtr startPtr = NULL; /* initially the artist list is empty */
FILE *musicFile;
char *artistTemp, *discTemp, *yearTemp, *trackTemp, *songTemp;

[Code] ....

C++ :: Record User Input But Combine It With Command Line Arguments?

Aug 15, 2013

I want to be able to write a program where I can record user input but combine it with command line arguments. For example I do a simple getline(); and the user types test how to combine it so it could be like test /q and it gives a different output depending on what additional input was added. Can this be done with lots of different inputs?

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++ :: Compiler Command Line Arguments

Jun 15, 2013

I have found this C++ online compiler (to use when I am at work): Compile and Execute C++ online

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?

C :: Simple Command Line Arguments

Jan 22, 2013

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.

C++ :: Entering Command Line Arguments?

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>

C/C++ :: Command Line Arguments With Integers?

Sep 10, 2014

I 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
", argv[0]);
if( argc == 2 ) {
printf("The argument supplied is %s
", argv[1]);

[code]...

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 ) {

[code]...

C++ :: Reading Command Line Arguments

Feb 7, 2012

I'm making a command line program for Maemo but have got a problem reading the args.

main.cpp

Code:
#include <cstdlib>
#include <string>
#include <sys/stat.h>
#include <sys/param.h>
#include <iostream>
#include "exceptions.h"
using namespace std;
struct settings {
//settings() : force(false), deps(false), repo(false) {}
[Code] ....

exceptions.cpp contains bodies of these functions.

Unfortunately the program doesn't seem to recognize the arguments

Code:
marcin@marcin:~/proj/meeinstall$ ./meeinstall -h
-h
Filename not provided.
Exiting...

How can I fix it?

C :: Incorporate Command Line Arguments Into Program?

May 26, 2014

In the following program, I have gotten it to work with IO redirection (not shown in this particular code), and have made some minor adjustments to get it to work with file processing. The only thing I have to do now is get it to work with command line arguments, and am slightly lost (and I have looked into it).

I basically just need to take a text file from a certain directory and send it to my program. Would need two files, an input and output file.

main.c
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "LAB_6B_7B.h"

Visual C++ :: Command Line Arguments To The Linker?

Sep 15, 2012

Code:

/** Add a feature to a (mutable) LV2 feature array. */
static inline void
suil_add_feature(LV2_Feature*** features,
unsigned* n,
const char* uri,
void* data) {
for (unsigned i = 0; i < *n && (*features)[i]; ++i) {
if (!strcmp((*features)[i]->URI, uri)) {

[Code] ....

suil_add_feature is used to add features to an existing array of pointers to type LV2_Feature. Initially, the array gets searched to see if the feature already exists. If it doesn't, the existing array gets increased by one element which then gets initialized to the new LV2_Feature value. Resizing is done using realloc()

I'm having a problem when I build a Debug version. The first 5 times I call suil_add_feature() realloc() ends up calling _realloc_dbg() (in dbgheap.c) and everything works fine. But on the sixth call, realloc() calls _realloc_base() (in realloc.c) which brings everything crashing down. I assume that _realloc_base() is intended for the normal (non-debug heap). So this particular app is somehow linking to both the debug and non-debug runtime modules.

If I was building using the VS IDE I could probably figure this out - but although my compiler is MSVC, my build environment is waf, which I'm a bit unfamiliar with. I'm guessing I need to add some lines to my waf script to let it know that it shuld ignore the non-debug runtime libraries when building a Debug version.

Can I achieve this by adding /NODEFAULTLIB to the linker options or is it more complicated than that?

C :: Function To Store Command Line Arguments In Array

Feb 1, 2015

In class, we have learned how to set up the main method so we can convert command line arguments to integers and utilize them. Here is an example of a method we learned to store command line arguments as integers in an array:

Code:
int main (int argc, constchar* argv[]) {int i;
int a[argc - 1];
// Fill the array with the arguments on the command line
for (i = 0; i < argc - 1; i++){
a[i] = atoi(argv[i + 1]);

[Code] .....

I understand that there are probably better ways to do it than using the atoi function, but for our purposes, the professor said this was okay.

Now, I am being asked to create a separate function to perform the same task (store integers in an array). I was told I would need to declare the array "out in the main program", and that the function would need to take at least 2 arguments: an array, and an array size.

Firstly, what should my return value be? My professor gave a hint that it would be important for me to figure out what the return value is, but I don't see why it would be anything else than void.

Also, wouldn't I need a third parameter? Perhaps the integers that are being stored in the array? (But how would I represent this as a parameter)?

Visual C++ :: Search Function - Ask User To Input Name And Brings Out Line From TXT File Containing Information
