RunOtherProgram

If you want your program to run another program and use that program's output. The code below executes the MS-DOS command 'dir' (similar to Linux 'ls') and puts the output of this command in a std::vector. Then it displays the output on screen.

Assumes you have already declared the FileExists and FileToVector functions.

Code in plain text can be found here.

#include <cstdlib>

#include <vector>

#include <fstream>

#include <string>

#include <cassert>

#include <iostream>

int main()

{

//From http://www.richelbilderbeek.nl/CppRunOtherProgram.htm

//Silenty executes 'dir' and writes the output to the file "temp.txt"

std::system("dir > temp.txt");

//Read "temp.txt" in a std::vector<std::string>

const std::vector<std::string> file(FileToVector("temp.txt"));

//Display the file

typedef std::vector<std::string>::const_iterator Iterator;

for (Iterator i = file.begin(); i!=file.end(); ++i)

{

std::cout << *i << std::endl;

}

//Wait for key press

std::cin.get();

}
