Re: I want to write a simple log file app in c++

I'm testing out the system() command. I coded the following. How can
I output the results into the given output file? Your help will be
appreciated.

/* system example : DIR */
//code based on:
http://www.cplusplus.com/reference/clibrary/cstdlib/system.html

#include <iostream>
#include <fstream>
#include <stdio.h>
#include <stdlib.h>
using namespace std;

int main ()
{
//opening the log file

   ofstream myLog;
   myLog.open("C:\\unisa\\MyFiles\\Test_bin\\myLog_test.txt");

//executing sytem() command

 int i;
 cout<<("Checking if processor is available...")<<endl;
 if (system(NULL)) puts ("Ok");
   else exit (1);
 cout<<("Executing command DIR...\n")<<endl;
 i=system ("dir"); //executing the DOS system command
 cout<<"The value returned was: "<<i<<endl;

//closing the log file

 myLog.close();

 return 0;
}
