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;
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?
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.
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:
% a.out Two roads diverged in a yellow wood wood yellow a in diverged roads Two
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 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 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
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".
I stumbled into this forum in frustration as I tried to pass a string with both quotes and spaces into a single variable. I have looked up a couple places online, and even saw an old post here (Handling spaces in command line arguments) However, I still cannot seem to get the following string (in between the ---'s) to stay in one command line argument.
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.
my professor just increased the problem by saying the time value should be passed as command line arguments can anybdy tell the code to parse time as command line arguments

/** 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?
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)?
How to get this thing to work. All i need to do is ask user to input a name and then it brings out the line from the .txt file containing the information.
For example in my case I'm doing a member search function I'm required to ask user to input the name of the customer and then print out all the details (which consumes 1 text line in the .txt file)
Here is the code, This is the write to text file method (100% working)
I am trying to create program which will process command line arguments and define which functions should be run, with specific order and specific arguments. This is my first problem:
Code: // proccessing_args.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <vector> #include <string> #include <iostream> #include <conio.h> using namespace std; int _tmain(int argc, _TCHAR* argv[])
[Code] ....
proccessing_argsproccessing_args.cpp(20): error C2143: syntax error : missing ',' before ':'
refers to the line with for. I copied the code form here [URL] .....
I'm just getting back into the swing of things after a long time of not programming. I'm trying to create a program which takes in command line arguments and prints the last one. My code is as follows:
#include <iostream> #include <vector> #include <string> using namespace std; int main() { string x; vector<string> arguments;
[Code]...
And the error message I receive, a simple but frustrating one, is as follows:
Enter arguments, enter STOP to stop: Segmentation fault...
