How do you make the output of a c++ program be interpreted as a UNIX
command? Example, what would a program that executed ls look like?

You should probably use 'system' function.

#include <cstdlib>
#include <iostream>

int main()
{
int status = EXIT_SUCCESS;

if(system(NULL))
system("ls");
else
{
std::cerr << "Command processor not available\n";
status = EXIT_FAILURE;
}

return status;
}
