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
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?
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
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:
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.
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
Code:
#include <stdio.h> int main(int argc, char **argv) { 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:
% a.out Two roads diverged in a yellow wood wood yellow a in diverged roads Two
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.
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.
int get_command_line (char * sa) { char * s; char * l = fgets(s, 300*5, stdin); int i = 0; int j; int n;
[Code] ....
The aim is to have the function return the number of arguments made after assigning each of the arguments to a c string stored in an array of five pointers. This is how I declare this:
int main(void) int n; char s0[300]; char s1[300]; char s2[300]; char s3[300];
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 ???
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 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
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'm fairly new to C++ and have been understanding until Ive hit this rock. Im trying to figure out how to indicate whether or not a first command line argument interpreted as an integer is a multiple of the sum of its own digits. I understand that logic as if you type 20 = 2(2+0) where 2 is a multiple and 3113 = 8 which is not a multiple but i feel hopeless trying to set it up. And here is my code.
Code: #include <iostream> using namespace std; int main(int argc, char*argv[]) {
