shell to be able to execute the most recent command and also be able to execute a specified command from the history. I have the printHistory function working properly. That is, when the user enters "history" it gives a list of the last ten commands entered. I need to add when the user enters "!!" to execute the most recent command and when the user enters "!n" n being an integer between 1 and 10, the specified command executes.
