Command Prompt Emulator

Hey a couple weeks back I had an idea of making a program that emulates command prompt. So it will be like a stand alone command prompt. I made that except I do not know how to make it give more than 1 word. I tried strings but it won't work. I tried doing 2 chars but i dont know how to do that. I tried thinks like system(c + d), where c and d are both chars i get from the user. How would I do this?

Here is a typical session:

I type in 'net user'
it gives the output of what i'd get when i would type just net by itself.

I need help!

Use an input command that allows for spaces (i.e., a line-based command).

Negative, after the space you get the next char value. How would you put both char values into command prompt?

post the code you have thus far.

Code:

---

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

int main()
{
    string hi;
    while (1)
    {
    cout << ">";
    getline(cin, hi);
    system (hi); //ERROR ZONE
   
    }
   
   
    system ("PAUSE");
    return 0;
}

Error: cannot convert `std::string' to `const char*' for argument `1' to `int system(const char*)'

And what does system(hi.c_str()) do for you?

Nothing.

maybe your program needs another while loop.

Tried. It doesn't. Why would it?

Let me be more specific: what does putting system(hi.c_str()); in place of the line system(hi), saving your source file, and recompiling do for you?

Hint: the answer is, "it fixes my problem."

It doesn't work. I'm using Dev-C++ compiler.

So am I. It does work, or at least this code does:

Code:

---

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

int main()
{
    string hi;
    while (1)
    {
    cout << ">";
    getline(cin, hi);
    system (hi.c_str()); //ERROR ZONE

    }


    system ("PAUSE");
    return 0;
}

Be sure to hit Ctrl-F11 to rebuild all. But it compiles clean and runs exactly like what you want. If you're getting compile errors, post them and we'll tell you what you've done wrong.

tabstop's right.
His code DID work, and thanks PRO for this code, it's gonna be helpful at school since they don't allow the use of cmd. :)
