    Use popen() to run a command, and collect the output of the command as if you were reading from a file opened with fopen().
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
