Replication of a DOS window?

I know this can be done, I've seen the code before... but I wanted to make my own without looking at anyone elses... you know?

I plan on taking inoput from the user and storing it into a string... then calling the system command with the string that holds the command...

Following? How is this done?

Take input from the user and store it in a string. Call the system() function with that string.

Nice signature.

Welcome to the boards.

Is there any specific type of string to use? Like a .. c string? maybe?

Obtain a string from the user (C++)

Other parts of the FAQ may help as well.

so it'd be like this:

Code:

---

#include <iostream>
#include <string>
using namespace std;

int main()
{
    string line;
   
    getline (cin, line );
    system( << line << );
 
}

---

or am I way off?

Close, but not quite (did you compile it and find out?) Normally you would just put line in the function call to pass it the string like this:

func(line);

With the system function, you can't pass a string variable, so you must do this:

system(line.c_str());

which passes a C-style string to the function. Also, you'll need to include the appropriate header to use the system function. In this case, that's <cstdlib>.

here's another part of the FAQ that may be useful: Run a program from within a program

just keep in mind that all somebody has to do is replace a program with their own and they can make your program run malicious code without even knowing it...

Thanks for the help guys
