this is my dungeonapp.rb file.I am using Ubuntu.Now how to execute this
code :
my_dungeon = Dungeon.new("Fred Bloggs")
my_dungeon.add_room(:largecave, "Large Cave", "a large cavernous cave",
{
:west => :smallcave })
my_dungeon.add_room(:smallcave, "Small Cave", "a small, claustrophobic
cave", {
:east => :largecave })
Question:
1.How to run this code from out of the file,like we do in java.Do I need
to go to irb prompt or usual command prompt for firing this code out of
the file.
2.When i copy the code of this file and directly paste on the irb prompt
it automatically add prefix "dungeonapp.rb" in each line! what is the
reason behind this.
Thank you guys.I need urgent help.
