Invoking DOS commands from C++

One quick question... how can I invoke some DOS commands from a C++ program ? Say I wanna do a "dir" or call some other executable from my C++ program. Is it possible ? How ?

Thanks.

#include <cstdlib>





int main()


{


System("dir"); // i forget if it is S or s in system on windows


return 0;


}

system not System

Thanks a lot ! That works ! But what if I wanna use the results for "dir" in my program ? Like how would I store a list of all the files and dirs in my program and then use it for some processing ?
