system("")

[cdh473]

I was wondering, is there ANY safe place to use system("")?
I am wanting to detect the OS version in a Windows system, and here's the code I'm using:

#include <iostream>

int main() {
    std::cout<<"Your PC is running under ";
    system("echo %OS%.");
    std::cin.get();
    return 0;
}

It's only going to be used on Windows.

There's also 1 more:

#include <iostream>
using namespace std;

int main() {
    cout<<"Press enter to see your PC info."<<endl;
    cin.get();
    cout<<endl;
    system("set");
    cin.get();
    return 0;
}

I'm also using it w/ Windows, just to show the PC info.

Are these safe?

Use GetVersionEx [http://msdn.microsoft.com/en-us/library/ms724451%28VS.85%29.aspx].

Don't use system, it's bad luck.

Functions like above are usable all over to replace the original commands or are even used in the original commands (or at least I would think).
