Simple, compile the program and pipe the output to sh or any shell.
Tested on a Red Hat Linux 7.3 bash shell.
The shell outputs are given below
-----------------------Shell outputs start--------------------------
[venkat@eagle venkat]$ cat test.cc
#include <iostream.h>
int main()
{
cout << "ls -l";
}
[venkat@eagle venkat]$ g++ -otest test.cc
[venkat@eagle venkat]$ ./test | sh
