#include <windows.h>

#include <conio.h>
#include <string>
#include <sstream>
#include <iostream>
using namespace std;
 
int main()
{
 
FILE *fp = popen("cmd.exe", "r+" );
char buff[50];
char command[50];
 
while (fp != NULL)
{
while ( fgets( buff, sizeof buff, fp ) != NULL ) 
{
  cout << buff;
}
cin.getline(command, sizeof command);
fputs(command, fp);
}
pclose( fp );
 
getch();  
 
}

#include <windows.h> #include <stdio.h> #include <conio.h> #include <string> #include <sstream> #include <iostream> using namespace std; int main() { FILE *fp = popen("cmd.exe", "r+" ); char buff[50]; char command[50]; while (fp != NULL) { while ( fgets( buff, sizeof buff, fp ) != NULL ) { cout << buff; } cin.getline(command, sizeof command); fputs(command, fp); } pclose( fp ); getch(); }

From this, I only get "Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp." when it starts, while I should also be getting the "C:\documents and settings\...." after it.
