create a folder, or use any DOS commands, in C++

[metal]

I'm creating a simple console app in c++, what is the best way to create a folder from this application? Also, is there any way to use DOS commands from a c++ console app? If so, I could just use md or mkdir. Thanks for any help in advance.

#include <cstdlib>

system("mkdir test");

one more question, implementing the system("mkdir") is there any way to use a variable in the folder name? I need to create a new folder in a for loop, named "Client ".... to get Client 1, Client 2, Client 3, etc...can this be done?

You pass a string to 'system()'... if you build the string it works just the same...

Careful passing strings to a function like that. A user could inject some nasty commands into it. Parse an user input carefully, especially be careful to remove "&". But i guess thats being a little paranoid, its all about who is using the application and what context it is running in. If its running on a server, then that would be a major concern.

For example, if its running on the server and you input "myfolder && format C: /s" as the folder name, your program would be running whatever command the user wants. If its running on a users machine, then the user is just hurting themselves ;-)

thanks for all the input.
actually, this is just a program to generate the configuration files required to play duke nukem 3d over a network, so I don't think there's a security issue there.
