After i type the above into

I am not sure which version of the course you are following, but in the 2014 version of cs50x breakout is pset4 (in 2015 has changed to pset3). And in order to play with staff's implementation you need to execute in a terminal.


But you need to be already in the pset4 directory in that terminal. So the current line in that terminal should look something like this:

jharvard@appliance (~/Dropbox/pset4): ~cs50/pset4/breakout
  • thanks, I can open this now :)
